  欢迎访问我的个人博客：www.zhangkangjia.info

2 环境准备

一台主机：

• httpd+php(fastcgi模式)
• mysql服务器

软件版本：

• CentOS 8 Steam
• mysql-8.0.19-linux-glibc2.12-x86_64.tar.xz
• apr-1.7.0.tar.bz2
• apr-util-1.6.1.tar.bz2
• httpd-2.4.43.tar.gz
• php-7.4.33.tar.gz
• wordpress-6.1.1-zh_CN.zip
• Discuz_X3.4_SC_UTF8_20220811.zip
• install_mysql5.7or8.0_for_centos.sh
  

3 实现步骤

3.1.1 二进制安装

install_mysql5.7or8.0_for_centos.sh编译安装mysql脚本

#!/bin/bash
. /etc/init.d/functions 
SRC_DIR=`pwd`
MYSQL='mysql-8.0.19-linux-glibc2.12-x86_64.tar.xz'
COLOR='echo -e \E[01;31m'
END='\E[0m'
MYSQL_ROOT_PASSWORD=123456
ln -s /usr/lib64/libtinfo.so.6.1 /usr/lib64/libtinfo.so.5
ln -s /usr/lib64/libncurses.so.6.1 /usr/lib64/libncurses.so.5

check (){

if [ $UID -ne 0 ]; then
  action "当前用户不是root,安装失败" false
  exit 1
fi

cd  $SRC_DIR
if [ !  -e $MYSQL ];then
        $COLOR"缺少${MYSQL}件"$END
		$COLOR"请将相关软件放在${SRC_DIR}目录下"$END
        exit
elif [ -e /usr/local/mysql ];then
        action "数据库已存在，安装失败" false
        exit
else
	return
fi
} 

install_mysql(){
    $COLOR"开始安装MySQL数据库..."$END
	yum  -y -q install libaio numactl-libs   libaio &> /dev/null
    cd $SRC_DIR
    xz -dk  mysql-8.0.19-linux-glibc2.12-x86_64.tar.xz
    tar xf mysql-8.0.19-linux-glibc2.12-x86_64.tar -C /usr/local/
    MYSQL_DIR=`echo $MYSQL| sed -nr 's/^(.*[0-9]).*/\1/p'`
    ln -s  /usr/local/$MYSQL_DIR /usr/local/mysql
    chown -R  root.root /usr/local/mysql/
    id mysql &> /dev/null || { useradd -s /sbin/nologin -r  mysql ; action "创建mysql用户"; }
        
    echo 'PATH=/usr/local/mysql/bin/:$PATH' > /etc/profile.d/mysql.sh
    .  /etc/profile.d/mysql.sh
	ln -s /usr/local/mysql/bin/* /usr/bin/
    cat > /etc/my.cnf <<-EOF
[mysqld]
server-id=1
log-bin
datadir=/data/mysql
socket=/data/mysql/mysql.sock                                                                                                   
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
[client]
socket=/data/mysql/mysql.sock
EOF
    mysqld --initialize --user=mysql --datadir=/data/mysql 
    cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld
    chkconfig --add mysqld
    chkconfig mysqld on
    service mysqld start
    [ $? -ne 0 ] && { $COLOR"数据库启动失败，退出!"$END;exit; }
    MYSQL_OLDPASSWORD=`awk '/A temporary password/{print $NF}' /data/mysql/mysql.log`
    mysqladmin  -uroot -p$MYSQL_OLDPASSWORD password $MYSQL_ROOT_PASSWORD &>/dev/null
    action "数据库安装完成" 
}
check
install_mysql

3.1.2为wordprss和discuz应用准备数据库和用户帐号

mysql -uroot -p123456
mysql> create database wordpress;
mysql> create database discuz;
mysql> create user wordpress@'IP或网段' identified by '密码';
mysql> grant all on wordpress.* to wordpress@'IP或网段';
mysql> create user discuz@'IP或网段' identified by '密码';
mysql> grant all on discuz.* to discuz@'IP或网段';

3.2 编译安装 httpd 2.4

#安装相关包
yum install gcc pcre-devel openssl-devel expat-devel -y

#编译安装httpd
tar xvf apr-1.7.0.tar
tar xvf apr-util-1.6.1.tar
tar xf httpd-2.4.46.tar 
mv apr-1.7.0 httpd-2.4.46/srclib/apr
mv apr-util-1.6.1 httpd-2.4.46/srclib/apr-util

cd httpd-2.4.46/

./configure \
--prefix=/apps/httpd \
--enable-so \
--enable-ssl \
--enable-cgi \
--enable-rewrite \
--with-zlib \
--with-pcre \
--with-included-apr \
--enable-modules=most \
--enable-mpms-shared=all \
--with-mpm=event

make && make install

编译完成：

准备PATH变量：

vim /etc/profile.d/lamp.sh
PATH=/apps/httpd/bin:$PATH
 . /etc/profile.d/lamp.sh

创建和配置用户和组:

useradd -s /sbin/nologin -r -u 88 apache

编辑配置文件:

vim /apps/httpd/conf/httpd.conf
user apache
group apache

修改为event模式,编译时已指定，此项不再需修改，可选:

vim /apps/httpd/conf/httpd.conf

LoadModule mpm_event_module modules/mod_mpm_event.so                             
     
#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

httpd -M |grep mpm
mpm_event_module (shared)

启动apache：

apachectl start

修改为以下内容：

[root@VM-0-3-centos ~]#vim /usr/lib/systemd/system/httpd.service
[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
Documentation=man:httpd(8)
Documentation=man:apachectl(8)
[Service]
Type=forking
#EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/apps/httpd/bin/apachectl start
#ExecStart=/apps/httpd/bin/httpd $OPTIONS -k start
ExecReload=/apps/httpd/bin/apachectl graceful
#ExecReload=/apps/httpd/bin/httpd $OPTIONS -k graceful
ExecStop=/apps/httpd/bin/apachectl stop
KillSignal=SIGCONT
PrivateTmp=true
[Install]
WantedBy=multi-user.target

启动成功：

3.3 编译安装 fastcgi 方式的 php 7.4

#安装相关包,依赖EPEL源

• php 7.4 相关包
  yum -y install gcc libxml2-devel bzip2-devel libmcrypt-devel sqlite-devel oniguruma-devel
  启用PowerTools源安装oniguruma-devel
  php7.4 编译

#解压
tar xvf php-7.4.33.tar.gz
#进入php目录
cd php-7.4.7/

./configure \
--prefix=/apps/php \
--enable-mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-openssl \
--with-zlib \
--with-config-file-path=/etc \
--with-config-file-scan-dir=/etc/php.d \
--enable-mbstring \
--enable-xml \
--enable-sockets \
--enable-fpm \
--enable-maintainer-zts \
--disable-fileinfo

编译安装
make && make install

准备PATH变量:

• 创建启动变量脚本

vim /etc/profile.d/lamp.sh
PATH=/apps/php/bin:/apps/httpd/bin:$PATH

• 初始化启动脚本

 . /etc/profile.d/lamp.sh

查看php版本，检查是否安装成功
php --version

准备php配置文件和启动文件

cp php.ini-production /etc/php.ini
cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/
cd /apps/php/etc
cp php-fpm.conf.default php-fpm.conf
cd php-fpm.d/
cp www.conf.default www.conf

修改进程所有者

vim /apps/php/etc/php-fpm.d/www.conf
user apache
group apache

支持status和ping页面

vim /apps/php/etc/php-fpm.d/www.conf
pm.status_path = /fpm_status
ping.path = /ping

支持opcache加速

mkdir /etc/php.d/
vim /etc/php.d/opcache.ini
[opcache]
zend_extension=opcache.so               
opcache.enable=1

初始化启动

systemctl daemon-reload
systemctl status php-fpm.service 
systemctl enable --now php-fpm.service

验证9000端口是否启动

可以看到9000端口已经启动！

3.4 修改配置 httpd 支持 php-fpm

vim /apps/httpd/conf/httpd.conf

• 取消下面两行的注释

• 修改下面行

<IfModule dir_module>
DirectoryIndex index.html
</IfModule>

更改为：

• 在文件最后面加上下面两行

AddType application/x-httpd-php .php
ProxyRequests Off

• 在文件最后面加上下面内容

#实现第一个虚拟主机
<virtualhost *:80>
servername blog.test.org
documentroot /data/wordpress
<directory /data/wordpress>
require all granted
</directory>
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/data/wordpress/$1
#实现status和ping页面
ProxyPassMatch ^/(fpm_status|ping)$ fcgi://127.0.0.1:9000/$1
CustomLog "logs/access_wordpress_log" common
</virtualhost>
#第二个虚拟主机
<virtualhost *:80>
servername forum.test.org
documentroot /data/discuz
<directory /data/discuz/>
require all granted
</directory>
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/data/discuz/$1
CustomLog "logs/access_discuz_log" common
</virtualhost>

• 创建主文件夹

mkdir /data/wordpress
mkdir /data/discuz

• 重新启动apache

apachectl restart

3.5 准备wordpress和discuz! 相关文件

• 准备wordpress程序文件

upzip wordpress-6.1.1-zh_CN.zip
mv wordpress/ /data/wordpress/

#准备discuz!程序文件

unzip  Discuz_X3.4_SC_UTF8_20220811.zip
mv upload/* /data/discuz/

chown -R apache.apache /data/*

3.6 测试访问

vim /etc/hosts
ip地址 forum.test.org blog.test.org

打开浏览器访问 http://blog.test.org 和http://forum.test.org 分别进行初始化和安装
云服务器一定打开3306端口，否则数据库会连接不上

3.7 安装成功

博客安装成功！

论坛安装成功！
