搭建LNAMP环境（五）- PHP7源码安装Redis和Redis拓展

一、安装Redis

1.创建redis用户组和用户

groupadd redis
useradd -r -g redis -s /sbin/nologin -M redis

2.下载redis源码包，将源码包放到/usr/local/src/目录下

下载页面：http://redis.io/download
这里用的是redis-3.2.5.tar.gz
下载地址：http://download.redis.io/releases/redis-3.2.5.tar.gz

3.进入src/目录

cd /usr/local/src/

4.解压源码包

tar -zxf redis-3.2.5.tar.gz

5.进入redis源码目录，编译安装

cd redis-3.2.5/

make PREFIX=/usr/local/redis install

6.创建redis文件目录

mkdir -p /usr/local/redis/data
mkdir -p /usr/local/redis/etc
mkdir -p /var/run/redis
mkdir -p /var/log/redis

7.将配置文件放入redis/etc/目录

cp redis.conf /usr/local/redis/etc/

8.修改redis配置文件redis.conf

vim /usr/local/redis/etc/redis.conf

9.修改为下面内容，保存退出

tcp-backlog 128                 　　#tcp队列长度，CentOS系统默认为128，此值不应该大于操作系统的该值
daemonize yes                 　　　#改为yes，保证redis可以后台运行
pidfile /var/run/redis/redis.pid   #redis pid
logfile "/var/log/redis/redis.log" #redis日志
dir /usr/local/redis/data/         #redis数据存储目录

#------ 可选配置 ------
#slaveof 192.168.1.66 6379 　　　　 #主从复制，在副机上配置，例：IP 192.168.1.66，端口 6379
#save 60 10000                     #快照，例：60s内10000个更改就保存
#appendonly yes                    #AOF持久化

10.修改redis目录权限

chown -R redis:redis /usr/local/redis
chown -R redis:redis /var/run/redis
chown -R redis:redis /var/log/redis

11.将redis命令加入环境变量，修改profile文件

vim /etc/profile

12.修改为下面内容，保存退出

PATH=/usr/local/mysql/bin:/usr/local/php/bin:/usr/local/redis/bin:$PATH

13.使/etc/profile里的配置立即生效

source /etc/profile

14.将redis服务脚本加入到init.d/目录，创建redisd文件

vim /etc/init.d/redisd

15.加入下面内容，保存退出

#!/bin/sh
#
# chkconfig:   35 84 16
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
 
. /etc/rc.d/init.d/functions
. /etc/sysconfig/network

                    echo -n "."
                done
                echo -e "\nRedis stopped"

        start

        echo "Please use start or stop as first argument"
        ;;
