一、实验名称：
LAMP分离部署
二、 实验目的：
很多人在搭建的时候都是使用的一台机器来部署LAMP环境，但是我们在实际的工作中一般都是分离部署的。也就是说MySQL是MySQL;它是一台单机，分离部署自己跑自己的服务，提高效率！
三、 实验环境：
OS：Centos7.5x86_64
Apache2.4 IP地址：192.168.100.11
PHP-5.5 IP地址：192.168.100.12
MySQL5.6IP地址：192.168.100.13
四：实验思路；
一：先在三台服务器上分别部署APACHE PHP MYSQL
二：调试Apache和PHP的协调
三：调试PHP和MySQL的协调
四：验证
具体操作步骤:
一：先把三台服务器IP调试同一个网段并关闭防火墙和内核安全机制
二：安装Apache
[root@localhost ~]# tar zxf httpd-2.4.29.tar.gz -C /usr/src/
[root@localhost ~]# cd /usr/src/httpd-2.4.29/
[root@localhost httpd-2.4.29]# yum -y insatll gcc* apr* pcre-devel

[root@localhost httpd-2.4.29]# vim /etc/init.d/httpd
#chkconfig: 35 80 80 #在第二行添加
[root@localhost httpd-2.4.29]# chmod a+x /etc/init.d/httpd
[root@localhost httpd-2.4.29]# chkconfig --add httpd
[root@localhost httpd-2.4.29]# chkconfig httpd on
[root@localhost httpd-2.4.29]# systemctl start httpd
[root@localhost httpd-2.4.29]# netstat -anpt | grep httpd

测试Apache
三：配置PHP
[root@localhost ~]# tar zxf php-5.5.38.tar.gz -C /usr/src/
[root@localhost ~]# cd /usr/src/php-5.5.38/
[root@localhost php-5.5.38]# ./configure --prefix=/usr/local/php --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --enable-fpm --enable-sockets --enable-sysvshm --enable-mbstring --with-libxml-dir=/usr --enable-xml --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --enable-maintainer-zts
[root@localhost php-5.5.38]# yum -y install libmcrypt* gcc* libxml2*
[root@localhost php-5.5.38]# make && make install
[root@php php-5.5.27]# useradd php
[root@localhost php-5.5.38]# cp php.ini-production /etc/php.ini
[root@localhost php-5.5.38]# vi /etc/php.ini
short_open_tag = On
default_charset = "UTF-8"
[root@php php-5.6.27]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.5.38]# chmod +x /etc/init.d/php-fpm
[root@localhost php-5.5.38]# chkconfig --add php-fpm
[root@localhost php-5.5.38]# chkconfig php-fpm on
修改php主配置，并编辑如下：
[root@localhost php-5.5.38]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@localhost php-5.5.38]# vi /usr/local/php/etc/php-fpm.conf
修改内容如下：
pid = run/php-fpm.pid
user = nginx
group = nginx
listen = 192.168.100.12:9000 //PHP主机的IP地址
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
修改完成后启动php服务
[root@localhost fpm]# systemctl start php-fpm
[root@localhost fpm]# netstat -anp | grep 9000
tcp 0 0 192.168.100.12:9000 0.0.0.0:* LISTEN 127576/php-fpm: mas
[root@localhost fpm]# mkdir /var/www
[root@localhost fpm]# echo "index.php" >> /var/www/index.php
[root@localhost ~]# yum -y install mysql
四：配置MySQL
（1）编译安装mysql
[root@localhost ~]# yum -y install ncurses-devel
[root@localhost ~]# tar zxvf cmake-2.8.6.tar.gz
[root@localhost ~]# cd cmake-2.8.6/
[root@localhost cmake-2.8.6]# ./configure
[root@localhost cmake-2.8.6]# gmake && gmake install
[root@localhost ~]# tar zxvf mysql-5.6.36.tar.gz
[root@localhost ~]# cd mysql-5.6.36/
[root@localhost mysql-5.6.36]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DSYSCONFDIR=/etc
[root@localhost mysql-5.6.36]# make && make install
（2）优化调整
[root@localhost mysql-5.6.36]# cp support-files/my-default.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
[root@localhost mysql-5.6.36]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql-5.6.36]# chmod +x /etc/init.d/mysqld
[root@localhost mysql-5.6.36]# chkconfig --add mysqld
[root@localhost mysql-5.6.36]# echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
[root@localhost mysql-5.6.36]# source /etc/profile
（3）初始化数据库
[root@localhost mysql-5.6.36]# groupadd mysql
[root@localhost mysql-5.6.36]# useradd -M -s /sbin/nologin mysql -g mysql
[root@localhost mysql-5.6.36]# chown -R mysql:mysql /usr/local/mysql
[root@localhost mysql-5.6.36]# yum -y install autoconf
[root@localhost mysql-5.6.36]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/
（4）启动mysql服务
[root@localhost mysql-5.6.36]# systemctl start mysqld
[root@localhost mysql-5.6.36]# mysqladmin -u root password 'pwd123'
[root@localhost mysql-5.6.36]# mysql -u root -p
Enter password:
mysql> create database aaa; ##创建aaa数据库
Query OK, 1 row affected (0.01 sec)
mysql> grant all on *.* to root@'192.168.100.12' identified by 'pwd123'; ##授权并指定密码
Query OK, 0 rows affected (0.00 sec)
五：在PHP上创建调用MySQL的测试页面
[root@localhost www]# vim mysql.php
<?php
$link=mysqli_connect('192.168.100.13','root','pwd123');
if($link)
echo "恭喜你，数据库连接成功！";
mysqli_close($link);
?>
访问测试
在客户端上访问：http://192.168.10.12
