生产环境下MySQL服务配置优化参考样本/CentOS 6.x MySQL 5.1.73

这里有mysql配置文件,分别是实体机生产环境下与vps下的两个版本;后面有二进制日志相关的配置。

注意事项:如果修改了innodb_*参数,尤其是修改了innodb_log_file_size ,启动前要删除/var/lib/mysql/ib_logfile{0,1}两个文件,启动后一定要检查一下mysql日志,是否有相关错误或警告消息。

环境 CentOS 6.x 自带的MySQL 5.1.73

在原始配置文件  /etc/my.cnf 基础上,在 [mysqld] 节内增加配置参数。实际应用中,请按硬件及负载酌情修改。

二进制日志的定期清理或手工清理

定时清理。通过参数 expire_logs_days 指定过期天数,过期自动清理;具体天数据按实际情况定(空间与同步延迟等)。该参数可运行时设定。

expire_logs_days = 10 

手工清理。root登录mysql客户端,执行purge命令。

> PURGE {MASTER | BINARY} LOGS TO 'log_name'
> PURGE {MASTER | BINARY} LOGS BEFORE 'date'

其中 log_name是show master logs; 显示的日志文件名,如 mysql-bin.000001. 应用举例:

> PURGE MASTER LOGS TO 'mysql-bin.000003';  //清除mysql-bin.000003(含)之前的日志
> PURGE MASTER LOGS BEFORE '2016-11-05 10:00:00';   //清除2016-11-05 10:00:00前的日志
> PURGE MASTER LOGS BEFORE DATE_SUB(NOW(),INTERVAL 3 DAY);
  //清除3天前日志,使用BEFORE函数计算日期,变量的date自变量还可以为'YYYY-MM-DD hh:mm:ss'格式。详查手册

清理二进制日志的影响。如果当前服务器有一个活跃的从属服务器,该从服务器当前正在读取您正在试图删除的日志之一,则本语句不会起作用,而是会失败,并伴随一个错误。不过,如果从属服务器是休止的,并且您碰巧清理了其想要读取的日志之一,则从属服务器启动后不能复制。当从属服务器正在复制时,本语句可以安全运行。您不需要停止它们。(参考

 

centos服务器安装后一系列配置参考(centos 6.x)

iptables

centos 6.x的iptables默认配置文件,开启必要的ssh,icmp/ping,不接受其它连接,有需要开放的端口再做手工开启;这是科学的。

不过,似乎,有些vps等环境下默认是空的,即接受任意连接;甚至没有安装iptables。这时,建议自行yum安装,并使用如下的默认配置文件,写入到 /etc/sysconfig/iptables,然后重启iptables。

# Generated by iptables-save v1.4.7 on Sat Dec 17 10:11:38 2011
# Manual customization of this file is not recommended.
*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

注意:默认拒绝FORWARD转发,果真有需要请自行开放。

sshd: 端口

ssh的服务器端,重要性不需多讲。

其主配置文件 /etc/ssh/sshd_config  (注意不是 /etc/ssh/ssh_config),下面sshd相关配置都在该文件上修改

改一下监听端口,虽然刻意扫描你,还是没的跑,但起码隐藏了一点点。大概13行,Port指令,默认是注释掉的,取消注释,将其后端口号22改成你想要改的,下面以12345为例。注意不要超过65535,不要使用其它已监听端口

Port 12345

[至关重要] iptables里打开相关端口,不要断开当前连接、重启sshd 服务,保存iptables配置到磁盘(以备下次开机时自动生效)

# iptables -I INPUT 4 -m state --state NEW -p tcp --dport 12345 -j ACCEPT
# /etc/init.d/sshd restart
# /etc/init.d/iptables save

再开一个ssh客户端测试连接,确保改后的端口可以连接。(即使已改过端口,当前连接也还是会保持的)

指定自定义端口的ssh连接: ssh -p 12345  username@your.host.ip

sshd: 用户白名单

限制一下允许通过ssh远程登录的用户名(白名单),可以在文件结尾增加如下一行

AllowUsers user1 user2 user3

其中的user1 user2 user3 是允许通过ssh远程登录的用户,多个用户使用空格分隔。当然,你要事先创建这些普通用户,不然下次就连不上了。

sshd: 禁止root用户直接通过ssh登录

被暴力破解root密码是一件经常遇到的事情,所以严重推荐禁止掉,尤其是使用默认22端口时。增加下一行配置

PermitRootLogin no

日期时间的自动同步

首先确保rdate已安装,使用美国授时中心服务器,加入到crontab,每周日同步一次

# crontab -e
* * * * 0 rdate -s time.nist.gov

详细可参考 linux下日期时间自动同步设置(rdate,ntpdate两种方法)

yum源

epel

似乎centos 6.x的某一个版本起,其官方yum默认包含了epel-release的yum源,直接安装即可。

yum install epel-release

nginx

如果使用nginx的话,可以使用nginx的官方yum源。当然里面只有nginx,没有别的包,所以不会破坏centos原装包的依赖关系。

rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

详细参考nginx官方yum源说明 http://nginx.org/en/linux_packages.html#stable

selinux

这货很强悍,然而有时也很麻烦,尤其是不够熟的时候,可以考虑关闭,配置在文件 /etc/sysconfig/selinux

SELINUX=disabled
或
SELINUX=permissive

apache/httpd

取消默认欢迎页,/etc/httpd/conf.d/welcome.conf 注释掉相关配置行,但不建议删除该文件。因为yum update更新后,这个文件可能被自动恢复。

添加文件 /etc/httpd/conf.d/vhost.conf, 配置虚拟站点,但建议第一个设置成空站点。因为第一个VirtualHost是默认站点,没有匹配的host主机名,都会被apache丢给默认站点。

NameVirtualHost *:80
<VirtualHost *:80>
        ServerName default.host.com
        DocumentRoot "/var/www/html/default/html/"
        <Directory "/var/www/html/default/html/">
                AllowOverride None
                Order allow,deny
                Allow from all
        </Directory>
        <IfModule mod_php5.c>
        php_admin_value open_basedir "/tmp/:/var/www/html/default/html"
        </IfModule>
</VirtualHost>

<VirtualHost *:80>
        ServerName www.vhost1.com
        DocumentRoot "/var/www/html/vhost1.com/www/"
        <Directory "/var/www/html/vhost1.com/www/">
                AllowOverride All
                Order allow,deny
                Allow from all
        </Directory>
        <IfModule mod_php5.c>
        php_admin_value open_basedir "/tmp/:/var/lib/php/session:/var/www/html/vhost1.com/"
        </IfModule>
</VirtualHost>

启用http压缩,gzip压缩是否有必要启用,观点并不一致(CentOS默认配置是不启用的),如需启用,确认一下 apache主配置文件中(大约1011行)已经启用了mod_deflate.so模块,新增文件 /etc/httpd/conf.d/http_gzip.conf ,内容如下

<ifmodule mod_deflate.c>
#压缩率, 6是建议值
DeflateCompressionLevel 6
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/atom_xml
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE image/svg+xml
</ifmodule>

禁止添加默认页面编码的http头,大概 759行

AddDefaultCharset UTF-8

最好注释掉,让浏览器自行选择编码,而不是弄巧成拙的强制UTF-8编码,造成非UTF-8页面全部乱码掉

MySQL-Server

CentOS 6.x/apache 2.2下php多版本共存探索(模块及fastCGI)/mod_fcgi,mod_proxy_fcgi实现

在apache下整合fastCGI模式运行的php-fpm,似乎网上很少相关材料,就连英文版材料也少。只要是php-fpm,基本上都是与nginx搭配。查了一大批相关资料,写本文总结一下。

apache下有多个fastCGI的支持方案:至少有mod_fcgimod_fastcgigit)、mod_proxy_fcgi等。这两个模块都有点老,尤其mod_fastcgi自从2007年以来就没有更新,略掉不谈,事实上没用过用。mod_proxy_fcgi模块是httpd 2.4+的版本正式引入,通过简洁的一行 ProxyPassMatch 指令即可。

mod_fcgi

mod_fcgi模块本身是做fastCGI进程管理的,使用它就不需要使用php-fpm管理进程了。核心配置参数

LoadModule fcgid_module modules/mod_fcgid.so
<VirtualHost *:80>
    DocumentRoot "/var/www/html/site_1"
    ServerName "www.yourhost.com"
    DirectoryIndex index.html index.php
    #php.ini的存放目录,Linux下通常不需要
    #FcgidInitialEnv PHPRC "D:/php"
    # 设置PHP_FCGI_MAX_REQUESTS大于或等于FcgidMaxRequestsPerProcess,防止php-cgi进程在处理完所有请求前退出
    FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 1000
    #php-cgi每个进程的最大请求数
    FcgidMaxRequestsPerProcess 1000
    #php-cgi最大的进程数
    FcgidMaxProcesses 3
    #最大执行时间
    FcgidIOTimeout 600
    FcgidIdleTimeout 600
    #php-cgi的路径
    FcgidWrapper /usr/local/php7/bin/php-cgi .php
    AddHandler fcgid-script .php
    FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 1000
    <Directory "/var/www/html/site_1">
        Options +ExecCGI
    </Directory>
</VirtualHost>

其中粗体着色是必须参数,其它几个Fcgid*指令,是优化之用,这里仅示例,要按实际情况调整数值。具体参看mod_fcgi官方文档

使用mod_fcgid的几个特点

  1. php-fgi进程是由apache模块启动并管理,不需要配置php-fpm
  2. 在php-cig进程以apache用户身份运行,php程序写的文件,其权限为apache用户(而不像php-fpm下写文件为php-fpm用户所有,默认是nobody),这样在目录权限管理方面一致性高些。

mod_fastcgi

虽然CentOS 6.x下是apache 2.2,但所幸已经有人成功移植: https://github.com/ceph/mod-proxy-fcgi 我们可以直接使用;更幸运的是它已经进入epel源,直接yum安装即可;不想匹配epel源的,直接下载rpm包安装也可以(示例 http://mirrors.ustc.edu.cn/epel/6/x86_64/

当然可以重新编译安装apache 2.4, 这样直接有mod_proxy_fcgi可以使用,但这里还是保持原版本不变,省掉编译的工作量。

参考mod_proxy_fcgi官方文档,整合php-fpm的配置指令

ProxyPassMatch "^/myapp/.*\.php(/.*)?$" "fcgi://localhost:9000/var/www/"

语法很简单,跟配置反向代理类似,可以按实际需要做修改。事实上与mod_proxy模块语法一致的,不同处是将http协议改成fcig协议。

以上是apache整合php-fpm模式运行的fastCGI,接下来要对yum安装的php做下配置修改。

yum安装的php配置文件 /etc/httpd/conf.d/php.conf ,其中有如下一行

AddHandler php5-script .php

我们要对不同的站点启用不同的php,上面一行是对全局的.php文件分配给php模块处理,我们把这一行注释掉。而是在每个站点启用不同的php运行模式。

以上即是处理方式。

[已知问题]:裸目录地址转发

有一个困扰的问题没有解决,感觉有点像模块bug:

对于配置了DirectoryIndex index.php的目录,如果其子目录没有index.php,上述ProxyPassMatch还是会做fastCGI转发,这时会看到php-fpm的404响应,而不是apache的响应403页面。但前面的规则并不转发这裸空目录的url,所以感觉像bug

再者就是,对于ProxyPassMatch匹配的目录,apache自动索引功能失效。(当然如果不开启autoindex就无所谓了。生产环境下通常不开启的)

其它,似乎也没有什么严重后果,或者我没还意识到(?)。

解决方法:每个目录下,都放置一个index.html,避免fpm-php处理空请求

 

linux/centos上安装配置gitosis(git服务器端)

gitosis长期没有更新了,换gitolite吧,或gitlab也行

[个人按本文方法是可以安装gitosis的,但在客户端git clone总是失败,也无法成功创建repo,所以个人改用gitolite,感觉比gitosis简单一些,而且一安装就可以正常工作]

安装gitosis,因为centos/redhat官方源不带gitosis,所以需要先添加EPEL软件仓库,或者手工下载gitosis的 rpm包及依赖包并手工安装。

gitosis rpm包安装后,会自动创建一个gitosis用户,为了简化其见,手工对其改名,改成git,涉及以下四个文件/etc/passwd, /etc/shadow, /etc/group, /etc/gshadow . 默认情况下,git用户(即改名前的gitosis用户)的home目录为 /var/lib/gitosis

这是git用户是作为git的管理账号之用。因为此时git用户没有设置登录密码,我们也不需要其密码,而是使用ssh密钥登录。但对gitosis的设置还是使用git用户登录比较方便。可以切换到root用户,然后 su git .

为git用户设置ssh密钥登录。上传一个ssh公钥,建议使用你的常用账号下的ssh公钥。并将其加入git用户的authorized_keys

sh-4.1$ cd ~/.ssh/
sh-4.1$ cat id_rsa.pub >>authorized_keys

确认可以使用公钥通过ssh登录。关于使用公钥自动登录ssh主机,更多可以参看这里 ssh无密码登入设置(完全版)/linux下免输入密码ssh登录

下面初始化gitosis . 要使用git用户执行下面命令

gitosis-init < [path of your id_rsa.pub]

结果大致如下

sh-4.1$ gitosis-init < id_rsa.pub
Initialized empty Git repository in /var/lib/gitosis/repositories/gitosis-admin.git/
Reinitialized existing Git repository in /var/lib/gitosis/repositories/gitosis-admin.git/
sh-4.1$ ls
gitosis  repositories

可以看到被创建的两个目录,gitosis与repositories .

运行 git clone git@localhost:repositories/gitosis-admin.git 即可把git管理配置文件的目同步到本地。需要修改配置,就在本地修改,然后git commit;git push同步到服务器上即可以即时生效了

关于gitosis资料,参考 http://linux-wiki.cn/wiki/zh-hans/%E9%85%8D%E7%BD%AEgitosis%EF%BC%88%E4%BB%A5CentOS%E4%B8%BA%E4%BE%8B%EF%BC%89

设置ssh自动登录远程主机的配置要点

本地生成的的RSA密钥传需要传到远程主机相应用户家目录下的.ssh子目录下,注意该子目录的权限设置是有严格要求的:其所属用户当然是该用户,其权限应该是700, 即不允许其它用户进入并访问该目录;否则,无法自动登录的。

这种情况下,使用ssh 的-v参数显示详细消息大致如下:

mysql修改配置参数innodb_log_file_size后不能正常工作,在phpmyadmin中innodb表状态为“使用中”

问题:修改mysql配置参数innodb_log_file_size 后,可能无法正常启用,或者innodb表将不能工作,在phpmyadmin中显示为“使用中”

解决方法:先停掉mysql,然后删掉旧innodb日志文件后,再启动mysqld就可以正常启用了.innodb旧日志文件位于mysql data 目录下的ib_logfile0, ib_logfile1 文件

innodb日志文件在linux下的典型位置为 /var/lib/mysql
在windows下则默认位于安装目录下的data子目录里。

原因:是旧的innodb日志文件,与改后的innodb_log_file_size不匹配,所以造成mysql不能正常工作。

从某主机商的虚拟主机上拷出来的apache 主配置文件

从美橙互联虚拟主机上拷出来的apache 主配置文件/etc/httpd/conf/httpd.conf

#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See for detailed information.
# In particular, see
#
# for a discussion of each configuration directive.
#
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "/etc/httpd" will be interpreted by the
# server as "/etc/httpd/logs/foo.log".
#

### Section 2: 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# definition. These values also provide defaults for
# any containers you may define later in the file.
#
# All of these directives may appear inside containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed. This address appears on some server-generated pages, such
# as error documents. e.g. admin@your-domain.com
#
ServerAdmin root@localhost

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work. See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make
# redirections work in a sensible way.
#
#ServerName www.example.com:80

#
# UseCanonicalName: Determines how Apache constructs self-referencing
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client. When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/var/www/html"

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#

Options FollowSymLinks
AllowOverride None

#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# This should be changed to whatever you set DocumentRoot to.
#

#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.

#
# UserDir: The name of the directory that is appended onto a user's home
# directory if a ~user request is received.
#
# The path to the end user account 'public_html' directory must be
# accessible to the webserver userid. This usually means that ~userid
# must have permissions of 711, ~userid/public_html must have permissions
# of 755, and documents contained therein must be world-readable.
# Otherwise, the client will only receive a "403 Forbidden" message.
#
# See also: http://httpd.apache.org/docs/misc/FAQ.html#forbidden
#

#
# UserDir is disabled by default since it can confirm the presence
# of a username on the system (depending on home directory
# permissions).
#

#
# To enable requests to /~user/ to serve the user's public_html
# directory, remove the "UserDir disable" line above, and uncomment

# TypesConfig describes where the mime.types file (or equivalent) is
# to be found.
#
TypesConfig /etc/mime.types

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain

#
# The mod_mime_magic module allows the server to use various hints from the

# HostnameLookups: Log the names of clients or just their IP addresses

# EnableMMAP: Control whether memory-mapping is used to deliver
# files (assuming that the underlying OS supports it).
# The default is on; turn this off if you serve from NFS-mounted

#
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a
# container, that host's errors will be logged there and not here.
#
ErrorLog logs/error_log

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.

# The following directives define some format nicknames for use with
# a CustomLog directive (see below).

LogFormat "%h %l %u %t \"%r\" %>s %b" common

# requires the mod_logio module to be loaded.
#LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio

#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a
# container, they will be logged here. Contrariwise, if you *do*
# define per- access logfiles, transactions will be
# logged therein and *not* in this file.
#
#CustomLog logs/access_log common

#
# If you would like to have separate agent and referer logfiles, uncomment
# the following directives.
#
#CustomLog logs/referer_log referer
#CustomLog logs/agent_log agent

#
# For a single logfile with access, agent, and referer information

#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory

#
# Aliases: Add here as many aliases as you need (with no limit). The format is

### Section 3: Virtual Hosts
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
#
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#

firefox弹出窗口错在新标签里打开/phpMyAdmin

使用phpMyAdmin,打开编辑sql语句,正常情况下是在新窗口中打开的,但突然变成新标签了,而且firefox的主窗口大小变成sql语句编辑窗口那么大小,很是难受。

之前也遇到过这种情况,当时是把当前用户目录下的firefox文件全部删掉(或者移走),这样对当前用户而言firefox就成了第一次使用,要重新配置,重新安装插件(当然也可以从备份文件里拷回相应目录、文件),这是一件很麻烦的工作。

这种问题出现过几次了。上次通过删除部分文件的方式,找到问题在于文件prefs.js。该文件里面很多配置项目,似乎是about:config配置项目保存的地方。但没有找到具体是哪一行或几行。

这次就单独针对本文件处理,折半法,删除一半,找问题在于哪一半,然后在有问题的一半里再删除其中一半....如此循环(或许叫递归),最终发现问题在于这样的一行:

user_pref("browser.link.open_newwindow.restriction", 0);

把这一行删掉,就可以了。不过这一行什么时候被添加上,什么时候会出现这样的问题,还不清楚。

phpMyAdmin配置:操作栏只显示“浏览,结构,编辑”等图标不显示文字

phpMyAdmin的强大便捷作用这里就不赘述。下载了phpMyAdmin 3.4.2,最新版本,界面有很大改变,比之前的花哨很多,包括大量的ajax应用。但它默认把操作一栏下的操作图标旁加入了文字,浪费屏幕宽度,使用其自带的config/配置一下,可以只显示图标,具体位置在

自定义主框架 -标签 -

$cfg['PropertiesIconic'] = true;

作相应修改,即可。
