```
#### 安装mysql

```
[[email protected] ~]# ls
anaconda-ks.cfg install.log.syslog
install.log mysql-5.5.32-linux2.6-x86_64.tar.gz
[[email protected] ~]# tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz -C /usr/local/
[[email protected] ~]# useradd -s /sbin/nologin -M mysql
[[email protected] ~]# echo "192.168.214.168 LNMP" >> /etc/hosts #MySQL服务器IP地址
[[email protected] ~]# ln -s /usr/local/mysql-5.5.32-linux2.6-x86_64/ /usr/local/mysql
# 初始化MySQL配置文件my.conf
[[email protected] ~]# cd /usr/local/mysql-5.5.32-linux2.6-x86_64/
[[email protected] mysql-5.5.32-linux2.6-x86_64]# /bin/cp support-files/my-small.cnf /etc/my.cnf
# 初始化mysql
[[email protected] mysql]# chown -R mysql.mysql /usr/local/mysql
[[email protected] mysql]# mount /dev/sr0 /media/cdrom
[[email protected] mysql]# yum -y install libaio
[[email protected] mysql]# /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/ --user=mysql
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/local/mysql/bin/mysqladmin -u root password ‘new-password‘
/usr/local/mysql/bin/mysqladmin -u root -h localhost.localdomain password ‘new-password‘

Alternatively you can run:
/usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/mysql/scripts/mysqlbug script!

```
#### 配置并启动MySQL数据库

```
[[email protected] mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[[email protected] mysql]# chmod +x /etc/init.d/mysqld
[[email protected] mysql]# /etc/init.d/mysqld start
Starting MySQL.. SUCCESS!
[[email protected] mysql]# netstat -antup | grep mysql

```
（2）编译安装PHP

```
[[email protected] php-5.3.28]# touch ext/phar/phar.phar
[[email protected] php-5.3.28]# make
[[email protected] php-5.3.28]# make install
[[email protected] php-5.3.28]# ln -s /usr/local/php5.3.28/ /usr/local/php
[[email protected] php-5.3.28]# cd /usr/local/php
[[email protected] php]# cd /usr/src/php-5.3.28/
[[email protected] php-5.3.28]# ls php.ini*
php.ini-development php.ini-production
[[email protected] php-5.3.28]# cp php.ini-production /usr/local/php/lib/php.ini
[[email protected] php-5.3.28]# cd /usr/local/php/etc/
[[email protected] etc]# ls
pear.conf php-fpm.conf.default
[[email protected] etc]# cp php-fpm.conf.default php-fpm.conf
[[email protected] etc]# /usr/local/php/sbin/php-fpm
[[email protected] etc]# netstat -antup | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 129604/php-fpm
[[email protected] etc]# vim php-fpm.conf
151 listen = 192.168.214.167:9000 #分离式部署，改为PHP服务器IP地址

```
#### 配置nginx支持PHP程序请求访问

```
[[email protected] etc]# cd /usr/local/nginx/conf/
[[email protected] conf]# cp nginx.conf nginx.conf.bak
[[email protected] conf]# vim nginx.conf
worker_processes 1;
error_log logs/error.log;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.yunjisuan.com;
root /www;
location / {
index index.php index.html index.htm;
}
location ~ .*.(php|php5)?$ {
fastcgi_pass192.168.214.167:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
}
# 配置nginx.conf配置文件并启动nginx
[[email protected] ~]# vim /usr/local/nginx/conf/nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;

server {
listen 80;
server_name www.yunjisuan.com;
root /www;
location / {
index index.php index.html index.htm; #添加一个动态文件
}
location ~ .*.(php|php5)?$ {
fastcgi_pass 192.168.214.167:9000; #PHPIP地址
fastcgi_index index.php;
include fastcgi.conf;
}
}
}
[[email protected] ~]# /usr/local/nginx/sbin/nginx -s reload
[[email protected] ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.214.169 www.yunjisuan.com
[[email protected] /]# mkdir -p www
[[email protected] /]# chown -R www.www /www/
[[email protected] /]# echo "123456" > index.php # index.php文件的位置必须与PHP服务器的一致，同时存在
#本机/我的电脑/磁盘C/Windows/system32/drivers/etc/hosts
192.168.214.169 www.yunjisuan.com

```
配置PHP服务器的配置文件

```
[[email protected] ~]# vim /usr/local/php/etc/php-fpm.conf

; will be used.
user = www
group = www

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; ‘ip.add.re.ss:port‘ - to listen on a TCP socket to a specific address on
; a specific port;
; ‘port‘ - to listen on a TCP socket to all addresses on a
; specific port;
; ‘/path/to/unix/socket‘ - to listen on a unix socket.
; Note: This value is mandatory.
listen = 192.168.214.167:9000

; Set listen(2) backlog. A value of ‘-1‘ means unlimited.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
;listen.backlog = -1

[[email protected] ~]# mkdir -p /www
[[email protected] ~]# cd /www/
[[email protected] www]# chown -R www.www /www/
[[email protected] www]# echo "daisy" > index.php
[[email protected] www]# vim test_mysql.php
<?php
//$link_id=mysql_connect(‘主机名‘,‘用户‘,‘密码‘);
$link_id=mysql_connect(‘192.168.214.168‘,‘yunjisuan‘,‘123456‘); # IP地址为MySQLIP地址
if($link_id){
echo "mysql successful by daisy ";
}else{
echo mysql_error();
}
?>

```

配置MySQL基本数据

```
[[email protected] ~]# mysql -uroot -p123456
mysql> grant all on *.* to ‘yunjisuan‘@‘%‘ identified by ‘123456‘;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye

```

用fastcgi方式实现负载均衡
1. 克隆服务器PHP2（用PHP服务器克隆）
（PHP2端）
```
[[email protected] ~]# vim /usr/local/php/etc/php-fpm.conf

; will be used.
user = www
group = www

; Set listen(2) backlog. A value of ‘-1‘ means unlimited.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
;listen.backlog = -1
[[email protected] ~]# /usr/local/php/sbin/php-fpm
[[email protected] ~]# ss -antup | grep 9000
tcp LISTEN 0 128 192.168.214.170:9000 *:* users:(("php-fpm",1518,7),("php-fpm",1519,0),("php-fpm",1520,0))
[[email protected] www]# vim index.php
daisy 2

```
（nginx端）

```
[[email protected] ~]# vim /usr/local/nginx/conf/nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream www{
server 192.168.214.167:9000; #反向代理的IP地址
server 192.168.214.170:9000;

}
server {
listen 80;
server_name www.yunjisuan.com;
root /www;
location / {
index index.php index.html index.htm;
}
location ~ .*.(php|php5)?$ {
fastcgi_pass www; # 目录名
fastcgi_index index.php;
include fastcgi.conf;
}
}
}
[[email protected] ~]# /usr/local/nginx/sbin/nginx -s reload

```
测试PHP访问MySQL
（PHP端）
```
[[email protected] www]# vim test_mysql.php
<?php
//$link_id=mysql_connect(‘主机名‘,‘用户‘,‘密码‘);
$link_id=mysql_connect(‘192.168.214.168‘,‘yunjisuan‘,‘123456‘); # IP地址为MySQLIP地址
if($link_id){
echo "mysql successful by daisy ";
}else{
echo mysql_error();
}
?>
```
（PHP2端）
```
[[email protected] www]# vim test_mysql.php
<?php
//$link_id=mysql_connect(‘主机名‘,‘用户‘,‘密码‘);
$link_id=mysql_connect(‘192.168.214.168‘,‘yunjisuan‘,‘123456‘); # IP地址为MySQLIP地址
