安装Nginx、MySQL、PHP
概念
LNMP是Linux Nginx MySQL PHP 的简写,把Nginx、MySQL以及PHP安装在Linux系统上,组成一个环境来运行PHP的脚本语言。
Nginx是类似Apache的一种Web服务软件
MySQL是比较小型的数据库软件
Apache和PHP需要在同一台机器上
(先安装c编译语言)
安装MySQL
切换目录
下载源码包
解压
给文件改名
挪动位置
建立MySQL用户
创建datadir,数据库文件会放到这里面
更改权限
可能的安装包(出现错误)
最后(出现两个ok)
复制配置文件
配置文件
# vi /etc/my.cnf
basedir是MySQL包所在路径
datadir是定义的存放数据的地方
port定义MySQL服务监听的端口(默认是3306)
server_id定义ID号
socket定义服务监听的的套接字地址
复制启动脚本文件并修改其属性
修改启动脚本
# vi /etc/init.d/mysqld
把启动脚本加入系统服务项,设定开机启动
检查MySQL是否启动(大于两行)
安装PHP
下载PHP
配置编译选项
./configure
> --prefix=/usr/local/php-fpm
> --with-config-file-path=/usr/local/php-fpm/etc
> --enable-fpm
> --with-fpm-user=php-fpm
> --with-fpm-group=php-fpm
> --with-mysql=/usr/local/mysql
> --with-mysql-sock=/tmp/mysql.sock
> --with-libxml-dir
> --with-gd
> --with-jpeg-dir
> --with-png-dir
> --with-freetype-dir
> --with-iconv-dir
> --with-zlib-dir
> --with-mcrypt
> --enable-soap
> --enable-gd-native-ttf
> --enable-ftp
> --enable-mbstring
> --enable-exif
> --disable-ipv6
> --with-pear
> --with-curl
> --with-openssl
可能出现的错误
编译安装
修改配置文件
# cp php.ini-production /usr/local/php-fpm/etc/php.ini
# vi /usr/local/php-fpm/etc/php-fpm.conf
写入以下内容
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files =1024
检验配置是否正确
复制配置文件
# cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
设置权限
# chmod 755 /etc/init.d/php-fpm
创建用户
# useradd -s /sbin/nologin php-fpm
启动php-fpm
设置开机启动
检测是否启动
安装Nginx
下载nginx
解压
配置编译选项
编译和安装
编写启动脚本
加入以下内容
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start()
{
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop()
{
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload()
{
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart()
{
stop
start
}
configtest()
{
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|restart|configtest}"
RETVAL=1
esac
exit $RETVAL
保存后更改权限
设置开机启动
更改配置文件
清空配置文件
编写启动脚本
# vi /usr/local/nginx/conf/nginx.conf
