编译安装基于 fastcgi 模式的多虚拟主机的wordpress和discuz的LAMP架构

实现CentOS 7 编译安装基于 fastcgi 模式的多虚拟主机的wordpress和discuz的LAMP架构

准备环境：

两台主机：
    一台主机：httpd+php(fastcgi模式)
    一台主机：mariadb 服务器

准备软件版本：

mariadb-10.2.27-linux-x86_64.tar.gz 通用二进制格式
apr-1.7.0.tar.bz2
apr-util-1.6.1.tar.bz2
httpd-2.4.41.tar.gz
php-7.4.0.tar.xz
wordpress-5.3-zh_CN.tar.gz
Discuz_X3.4_SC_UTF8【20190917】.zip

主机名修改用以区分

# 作为httpd和php服务器使用
[root@centos7 ~]$hostname websrv
[root@centos7 ~]$exit
[root@websrv ~]$

# 作为数据库使用
[root@centos7 ~]$hostname mysql
[root@centos7 ~]$exit
[root@mysql ~]$

数据库服务器

实现数据库二进制安装（并加上LAMP需要的配置）

1. 准备好二进制mariadb安装包

[root@centos7 data]$ll
total 449668
-rw-r--r-- 1 root root 460459738 Sep 12 09:08 mariadb-10.2.27-linux-x86_64.tar.gz

1. 解压安装包

[root@centos7 data]$tar xvf mariadb-10.2.27-linux-x86_64.tar.gz
[root@centos7 data]$ll
total 449668
drwxrwxr-x 12 yang yang       282 Sep 10 02:02 mariadb-10.2.27-linux-x86_64
-rw-r--r--  1 root root 460459738 Sep 12 09:08 mariadb-10.2.27-linux-x86_64.tar.gz

1. 把解压后的数据库目录移动到usr/local下统一管理

[root@centos7 data]$mv mariadb-10.2.27-linux-x86_64 /usr/local/  # 移动
 
[root@centos7 local]$ln -s /usr/local/mariadb-10.2.27-linux-x86_64/ /usr/local/mysql  # 创建软连接
[root@centos7 local]$ll /usr/local/mysql
lrwxrwxrwx 1 root root 40 Dec 15 14:44 /usr/local/mysql -> /usr/local/mariadb-10.2.27-linux-x86_64/

1. 创建服务用户，并修改mysql目录下的权限。

[root@centos7 data]$useradd -s /sbin/nologin -d /data/mysql -r -u 306 mysql   # 创建服务用户

[root@centos7 local]$chown -R root.root mysql/*   # 修改为root
[root@centos7 local]$ll mysql/

1. 创建数据库

[root@centos7 mysql]$/usr/local/mysql/scripts/mysql_install_db --datadir=/data/mysql --user=mysql
Installing MariaDB/MySQL system tables in '/data/mysql' ...
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
# 创建数据库时缺少包（libaio）

[root@centos7 mysql]$yum install libaio -y  # 下载依赖包

[root@centos7 mysql]$/usr/local/mysql/scripts/mysql_install_db --datadir=/data/mysql --user=mysql  # 创建数据库（/data下没有这个目录会自动创建）

[root@centos7 mysql]$ll /data/
total 449668
-rw-r--r-- 1 root  root 460459738 Sep 12 09:08 mariadb-10.2.27-linux-x86_64.tar.gz

drwx------ 2 mysql mysql       20 Dec 15 14:55 performance_schema
drwx------ 2 mysql mysql       20 Dec 15 14:55 test

1. 准备配置文件(指明数据库路径)

[root@centos7 ~]$cp /usr/local/mysql/support-files/my-huge.cnf /etc/my.cnf -b  # 找到解压目录下的配置文件替换掉/etc下的配置文件并备份
cp: overwrite ‘/etc/my.cnf’? y
# 原系统/etc下就有一个my.cnf的配置文件但是需要改配置


[root@centos7 mysql]$vim /etc/my.cnf
[mysqld]
datadir=/data/mysql   # 加上这一行就够了 （需要启用二进制日志啊之类的根据需要启动）

如果上一步cp没做直接用的自带的文件，注意sock路经。（服务可能起不来是因为启动过一次之后系统建立了一个sock路径但是用的是系统自带的配置文件建立的路径。你在拷贝配置文件过去后一定要确保没有启动过服务。如果启动过请重启电脑或删掉旧的配置文件建立的sock文件再启动服务）

1. 制作启动服务（类似于centos6的启动脚本）

[root@centos7 mysql]$cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld  # 拷贝目录下的server启动脚本到

[root@centos7 mysql]$chkconfig --list    # 查看注册了哪些服务

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

netconsole      0:off   1:off   2:off   3:off   4:off   5:off   6:off
network         0:off   1:off   2:on    3:on    4:on    5:on    6:off

[root@centos7 mysql]$chkconfig --add mysqld   # 添加服务

[root@centos7 mysql]$chkconfig --list   # 再次查看

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off
netconsole      0:off   1:off   2:off   3:off   4:off   5:off   6:off
network         0:off   1:off   2:on    3:on    4:on    5:on    6:off   # 添加上了

1. 添加PATH变量

[root@centos7 ~]$echo "PATH=/usr/local/mysql/bin:$PATH" > /etc/profile.d/mysql.sh 
[root@centos7 ~]$. /etc/profile.d/mysql.sh

1. 创建部署软件需要的数据库和用户并授权

# 创建数据库

1. 合并三个目录一起编译

[root@centos7 data]$mv apr-1.7.0 httpd-2.4.41/srclib/apr
[root@centos7 data]$mv apr-util-1.6.1 httpd-2.4.41/srclib/apr-util

1. 下载相关依赖包

[root@centos7 data]$yum install gcc pcre-devel openssl-devel expat-devel -y

1. 进入目录下进行编译安装

[root@centos7 data]$cd httpd-2.4.41/  # 进入目录
[root@centos7 httpd-2.4.41]$./configure \
> --prefix=/app/httpd24 \
> --enable-so \
> --enable-ssl \

> --with-zlib \
> --with-pcre \
> --with-included-apr \
> --enable-modules=most \
> --enable-mpms-shared=all \
> --with-mpm=prefork

[root@centos7 httpd-2.4.41]$make -j 4 && make install   # 制作安装

1. 准备PATH变量

[root@centos7 httpd-2.4.41]$echo 'PATH=/app/httpd24/bin:$PATH' > /etc/profile.d/lamp.sh  # 添加变量
[root@centos7 httpd-2.4.41]$. /etc/profile.d/lamp.sh   # 加载变量

[root@centos7 httpd-2.4.41]$echo $PATH  # 查看变量
/app/httpd24/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

1. 创建apache账户

# 工作中最好指明UID，UID要统一.
[root@centos7 httpd-2.4.41]$useradd -s /sbin/nologin -r -u 88 apache

1. 修改httpd配置文件

[root@centos7 httpd-2.4.41]$vim /app/httpd24/conf/httpd.conf

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.  
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User apache   # 默认为daemon监管改为apache
Group apache  # 同上



# 网站主页面定义为/data/（随自己需求）
DocumentRoot "/data/"

1. 启动服务

[root@centos7 httpd-2.4.41]$apachectl restart

1. 修改ServerName配置不在提示

[root@centos7 httpd-2.4.41]$vim /app/httpd24/conf/httpd.conf
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName www.example.com:80   # 这一行取消注释，名字是什么都可以。

[root@centos7 httpd-2.4.41]$apachectl restart   # 不在提示
[root@centos7 httpd-2.4.41]$

1. 修改为event模式

[root@centos7 httpd-2.4.41]$vim /app/httpd24/conf/httpd.conf 
#  默认centos7为prefork模式，所以需要修改
LoadModule mpm_event_module modules/mod_mpm_event.so    # 取消注释启用
#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so # 加上注释禁用
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

[root@centos7 httpd-2.4.41]$apachectl restart

1. 可以根据需求调节这些配置对应生产调到生产中最大值

[root@centos7 httpd-2.4.41]$vim /app/httpd24/conf/extra/httpd-mpm.conf
# event MPM
# StartServers: initial number of server processes to start
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestWorkers: maximum number of worker threads
# MaxConnectionsPerChild: maximum number of connections a server process serves
#                         before terminating

    StartServers             3
    MinSpareThreads         75
    MaxSpareThreads        250
    ThreadsPerChild         25
    MaxRequestWorkers      400
    MaxConnectionsPerChild   0

现在httpd服务已经可以访问了！

web界面测试访问(it works! 是默认显示)

# 拷贝过去作为启动文件
[root@centos7 php74]$cp /data/php-7.4.0/sapi/fpm/php-fpm.service /usr/lib/system
d/system

# 重新加载服务
[root@centos7 php74]$systemctl daemon-reload

1. 修改配置httpd 支持php-fpm

# 启用代理
#LoadModule remoteip_module modules/mod_remoteip.so
LoadModule proxy_module modules/mod_proxy.so    # 启用
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
#LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
#LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so  # 启用

# 添加index.php

    DirectoryIndex index.php index.html


# 添加这三行
AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    ProxyRequests Off

# 多虚拟主机和status启用

servername wordpress.atotaobao.org
documentroot /data/wordpress

require all granted

ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/data/wordpress/$1

ProxyPassMatch ^/(status|ping)$ fcgi://127.0.0.1:9000/$1
CustomLog "logs/access_wordpress_log" common



servername discuz.taotaobao.org
documentroot /data/discuz

require all granted

ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/data/discuz/$1
CustomLog "logs/access_discuz_log" common

1. 创建部署软件需要的目录并建立一个测试php文件测试使用

[root@centos7 php74]$mkdir /data/wordpress
[root@centos7 php74]$mkdir /data/discuz

[root@centos7 php74]$vim /data/discuz/test.php


[root@centos7 php74]$cp /data/discuz/test.php /data/wordpress/

• windows更改host文件
  
• 添加这一行对应虚拟主机的域名和虚拟机ip
  
• web界面测试
  
• web状态页测试
  
• web界面ping测试
  

1. 准备opcache加速

• 查找opcache.so模块路径

[root@centos7 wordpress]$locate opcache.so
/app/php74/lib/php/extensions/no-debug-zts-20190902/opcache.so   # 这个是opcache加速模块 
/data/php-7.4.0/ext/opcache/.libs/opcache.so
/data/php-7.4.0/modules/opcache.so

# 这三个文件是一样的只是在不同目录里作用不同
[root@centos7 wordpress]$ll /app/php74/lib/php/extensions/no-debug-zts-20190902/opcache.so
-rwxr-xr-x 1 root root 2491984 Dec 15 17:15 /app/php74/lib/php/extensions/no-debug-zts-20190902/opcache.so
[root@centos7 wordpress]$ll /data/php-7.4.0/ext/opcache/.libs/opcache.so
-rwxr-xr-x 1 root root 2491984 Dec 15 17:15 /data/php-7.4.0/ext/opcache/.libs/opcache.so
[root@centos7 wordpress]$ll /data/php-7.4.0/modules/opcache.so
-rwxr-xr-x 1 root root 2491984 Dec 15 17:15 /data/php-7.4.0/modules/opcache.so

• 准备加速插件文件（用来加速php处理动态资源）

[root@centos7 wordpress]$mkdir /etc/php.d/
[root@centos7 wordpress]$vim /etc/php.d/opcache.ini
[opcache]
zend_extension=opcache.so
#zend_extension=/app/php74/lib/php/extensions/no-debug-zts-20190902/opcache.so
opcache.enable=1   # 1 启用   0 关闭

# 路径以写全也可以只写模块名都可以找到。

[root@centos7 wordpress]$systemctl restart php-fpm.service  # 重启服务

部署wordpress和discuz

1. 解压wordpress

[root@centos7 wordpress]$rm -rf /data/wordpress/   # wordpress 不用准备目录里面的所有文件都需要

-rw-r--r--  1 root root 12423575 Dec 12 14:18 wordpress-5.3-zh_CN.tar.gz

1. 解压discuz

[root@centos7 data]$unzip wordpress-5.3-zh_CN.tar.gz   # 解压没有这个解压软件
-bash: unzip: command not found
[root@centos7 data]$yum install unzip    # 下载解压软件

[root@centos7 ~]$unzip Discuz_X3.4_SC_UTF8【20191201】.zip -d /opt  # 指定目录安装因为有的东西不能放在网站主页目录下

[root@centos7 ~]$rm -f /data/discuz/test.php   # 删除之前的测试文件
[root@centos7 ~]$mv /opt/upload/* /data/discuz/  # 把upload下的所有文件移动到discuz目录下

1. 修改权限

[root@centos7 ~]$cd /data/
[root@centos7 data]$chown -R apache.apache discuz/ wordpress

web界面测试wordpress






web界面测试discuz

测试性能

1. 找一台虚拟机当客户端，现在客户端添加主机头解析。

[root@centos ~]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.39.7 wordpress.taotaobao.org discuz.taotaobao.org  # 添加这一行就行了

1. 使用ab命令测试

# 如果没有这个命令下载这个包
[root@centos ~]# yum install httpd-tools

[root@centos ~]# ab -c 10 -n 100 http://wordpress.taotaobao.org/  # 测试
