1. 源码安装mysql

鉴于前边的文章已经详细说过mysql的源码安装 可以点击基于LAMP的Discuz论坛的实现（源码安装）自行查看 这里为了节省时间 用一个shell脚本进行mysql的源码安装 用到的mysql依然是5.6.46 没有源码包的同学可以点击 【mysql-5.6.46.tar.gz 提取码：nli5】进行下载

[root@localhost ~]# cat my.sh 
#!/bin/bash
yum -y install bison cmake ncurses-devel openssl-devel perl-Data-Dumper 
tar -zxf mysql-5.6.46.tar.gz 
cd mysql-5.6.46
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all
make -j4 && make install
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib
ln -s /usr/local/mysql/bin/* /usr/local/bin/
useradd -M -s /sbin/nologin mysql
chown -R mysql:mysql /usr/local/mysql/
cd support-files/
\cp my-default.cnf /etc/my.cnf
cp mysql.server /etc/init.d/mysqld
sed -i '/^basedir=/c basedir=/usr/local/mysql' /etc/init.d/mysqld
sed -i '/^datadir=/c datadir=/usr/local/mysql/data' /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld 
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
[root@localhost ~]# bash my.sh

2. 源码安装nginx

对于nginx的安装，可以使用nginx安装、配置文件、虚拟主机、平滑升级、访问控制、启动脚本中的方法 但是 如果只是简单使用 没有复杂的模块的配置 可以使用如下的方式 快速安装 不需要添加用户 后期需要指定用户的时候修改配置文件即可

yum -y install gcc gcc-c++ pcre-devel zlib-devel openssl-devel
tar -zxf nginx-1.15.4.tar.gz 
cd nginx-1.15.4
./configure && make && make install
ln -s /usr/local/nginx/sbin/nginx  /usr/local/sbin/
nginx -v

3. 源码安装php

yum -y install gd libxml2-devel libjpeg-devel libpng-devel
tar -zxf php-7.2.0.tar.gz 
cd php-7.2.0
./configure --prefix=/usr/local/php --with-gd --with-zlib --with-pdo-mysql=mysqlnd --with-mysqli=/usr/local/mysql/bin/mysql_config --with-config-file-path=/usr/local/php --enable-mbstring --enable-fpm --with-jpeg-dir=/usr/lib
make -j4 && make install
cp php.ini-development /usr/local/php/php.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
cp php-fpm.d/www.conf.default php-fpm.d/www.conf
ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/

4. 修改nginx配置

[root@localhost etc]# vim /usr/local/nginx/conf/nginx.conf
 43         location / {
 44             root   html;
 45             index  index.php index.html index.htm; #此行加index.php 在最前边
 46         }
65-71行取消注释
 65         location ~ \.php$ {
 66             root           html;
 67             fastcgi_pass   127.0.0.1:9000;
 68             fastcgi_index  index.php;
 69             fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
 70             include        fastcgi.conf; #此行改为fastcgi.conf
 71         }

检测语法

[root@localhost etc]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

5. 编辑测试页面

[root@localhost etc]# vim /usr/local/nginx/html/test1.php

<?php
phpinfo();
?>

[root@localhost etc]# vim /usr/local/nginx/html/test2.php

<?php
$con = new mysqli('127.0.0.1','root','123456');
if(!$con)
  die("connect error:".mysqli_connect_error());
else
  echo "connet mysql server ok!\n";
?>

6. 启动服务并测试

启动nginx（如果之前已启动则reload）并确保nginx是运行状态

[root@localhost ~]# nginx
[root@localhost ~]# netstat -anput | grep LISTEN | grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      24989/nginx: master 

启动php 并确保php是运行状态

[root@localhost ~]# /etc/init.d/php-fpm start
Starting php-fpm  done
[root@localhost ~]# netstat -anput | grep LISTEN | grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      25017/php-fpm: mast

确保mysql服务是开启的 如果没有开启 则开启

[root@localhost ~]# netstat -anput | grep LISTEN | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      18338/mysqld

分别访问http://nginx的ip/test1.php http://nginx的ip/test2.php 进行测试 如下结果则OK

7. 部署Discuz论坛

论坛安装的操作与LAMP中的基本一致 在这里 web界面的操作 就不在做赘述了 可以参考 基于LAMP的Discuz论坛的实现（源码安装）里论坛的安装 里边有详细步骤和说明

[root@localhost ~]# cd /usr/local/nginx/html/
[root@localhost html]# mkdir backup
[root@localhost html]# mv *.* backup/
[root@localhost html]# ls
backup
[root@localhost html]# cd
[root@localhost ~]# unzip ComsenzDiscuz-DiscuzX-master.zip 
[root@localhost ~]# cp -r DiscuzX/upload/* /usr/local/nginx/html/
[root@localhost ~]# chmod -R 777 /usr/local/nginx/html/
[root@localhost ~]# firefox http://192.168.20.128/install/index.php
