Centos7安装Redis并设置开机自启动图文详解

1. 下载redis

wget http://download.redis.io/releases/redis-6.0.0.tar.gz
# 如果提示没有wget使用如下命令
# yum -y install wget

2.安装

#解压
tar -zxvf redis-6.0.0.tar.gz
#进入解压目录
cd redis-6.0.0
#指定安装目录
make install  PREFIX=/usr/local/redis

3.设置后台运行

• 复制redis.conf配置文件到bin

cp redis.conf /usr/local/redis/bin

• 修改配置信息

vim /usr/local/reids/bin/redis.conf
查询到 daemonized 修改no为yes
查询到 bind 127.0.0.1 注释掉,主要配置文件中有两个
查询 requirepass 1234  设置密码

4. 设置开机自启动

• 编写脚本

vim /etc/init.d/redis

• 文件内容,需要注意修改exec服务端路径,redis_cli客户端路径,conf配置文件路径,auth密码

                ${0} start   
                ;;   
        *)   
               echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2  
                exit 1

chmod 755 /etc/init.d/redis

• 启动redis

/etc/init.d/redis start
/etc/init.d/redis stop
