Mysql：192.168.2.151

【Nginx】

[root@DBserver ~]# yum install -y cmake ncurses-devel

[php]

[root@www ~]# yum install -y libxml2-devel bzip2-devel libcurl-devel libmcrypt-devel

[root@www ~]# tar -jxvf php-5.6.8.tar.bz2 -C /usr/src/

[root@www php-5.6.8]# ./configure --prefix=/usr/local/php --with-mysql --with-pdo-mysql --with-mysqli --with-openssl --enable-fpm --enable-sockts --enable-mbstring --with-jpeg-dir --with-png-dir --with-libxml-dir=/usr/ --with-config-file-path=/etc/ --with-config-file-scan-dir=/etc/php.d --with-curl

[root@www php-5.6.8]# make

[root@www php-5.6.8]# make install

[root@www php-5.6.8]# cp php.ini-production /etc/php.ini
[root@www php-5.6.8]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@www php-5.6.8]# chmod +x /etc/init.d/php-fpm
[root@www php-5.6.8]# chkconfig --add php-fpm
[root@www php-5.6.8]# chkconfig php-fpm on
[root@www php-5.6.8]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

[root@www etc]# sed -i '235s#pm.max_children = 5#pm.max_children = 150#;s#pm.start_servers = 2#pm.start_servers = 8#;s#pm.min_spare_servers = 1#pm.min_spare_servers = 8#;s#pm.max_spare_servers = 3#pm.max_spare_servers = 10#g' /usr/local/php/etc/php-fpm.conf

配置php-fpm的 Pid文件路径

[root@www etc]# sed -i 's#;pid = run/php-fpm.pid#pid = /usr/local/php/var/run/php-fpm.pid#g' /usr/local/php/etc/php-fpm.conf

在php-fpm配置文件配置用户名为nginx，用nginx用户来启用php-fpm程序，而监听地址为本地IP用来调用

[root@www etc]# sed -i 's#user = nobody#user = nginx#;s#group = nobody#group = nginx#;s#listen = 127.0.0.1:9000#listen = 192.168.2.144:9000#g' /usr/local/php/etc/php-fpm.conf

【整合Nginx与PHP】

worker_processes  ;
events {
    worker_connections  ;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  ;
    server {
        listen       ;
        server_name  localhost;
        location / {
            root   /www/webapp/;
            index index.php index.html index.htm;
        }
           location ~ \.php$ {
             root           /www/webapp;
               fastcgi_pass   192.168.2.144:;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
           }
        error_page        /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

[root@www etc]# mkdir /www/webapp -p

[root@www etc]# useradd -M -s /sbin/nologin  nginx

[root@www etc]# systemctl start php-fpm

netstat -anput | grep php-fpm
tcp 0 0 192.168.2.144:9000 0.0.0.0:* LISTEN 126357/php-fpm: mas

[root@www ~]# cat /www/webapp/index.php
<?php
phpinfo();
?>

Ps：如果PHP单独在一个服务独立运行的话。可以用nfs共享，指定php-fpm的本地IP进行挂载

1 mkdir /www
2 chown -R nginx:nginx /www
3 vim /etc/exports
4 ---------------------------------------------
5 /www    192.168.2.0/24(rw,no_root_squash)
6 ---------------------------------------------
7 service nfs start

8 mount -t nfs 192.168.2.144:/www /www
【Discuz论坛】

[root@www ~]# unzip Discuz_X3.1_SC_UTF8.zip -d /www/webapp

[root@www ~]# cd /www/webapp
[root@www webapp]# mv upload/* .

[root@www webapp]# chmod 777 -R data/ config/ uc_client/ uc_server/

【数据库授权】

[root@DBserver mysql-5.5.38]# mysql -u root -p123.com

mysql> create database Discuzdb default charset=utf8;

mysql> grant all on Discuzdb.* to root@'mysql> grant all on Discuzdb.* to root@'192.168.2.144' identified by '123456';
