1. 获取安装包：redis-4.0.2.tar.gz@H_301_7@
http://download.redis.io/releases/redis-4.0.2.tar.gz@H_301_7@
2.上传到centos主机，比如目录 /usr/local (下文的操作都基于此目录)@H_301_7@
3. 解压@H_301_7@
cd/usr/local@H_301_7@
tar -zxvf redis-4.0.2.tar.gz@H_301_7@
4. 编译安装@H_301_7@
cd redis-4.0.2@H_301_7@
make install@H_301_7@
5. 目录结构如下@H_301_7@
[root@localhost redis-4.0.2]# ls -ll

6.以非daemon模式启动@H_301_7@
src/redis-server@H_301_7@
7. 再打开一个终端，连接到centos服务器,验证redis服务是否正常。执行redis-cli命令，进入交互模式@H_301_7@
[root@localhost redis-4.0.2]# redis-cli
127.0.0.1:6379> set a 1
OK
127.0.0.1:6379> get a
"1"
127.0.0.1:6379>@H_301_7@
看到上面的输出，说明redis安装、启动都正常。@H_301_7@
配置redis为系统的服务@H_301_7@
8.停止上述第6步中启动的redis服务。直接：ctrl+c@H_301_7@
9.在/etc下创建redis目录@H_301_7@
mkdir /etc/redis@H_301_7@
@H_301_7@
10. 复制redis.conf配置文件(6379为redis服务的端口)@H_301_7@
cp /usr/local/redis-4.0.2/redis.conf /etc/redis/6379.conf@H_301_7@
@H_301_7@
11. 修改配置文件6379，vi /etc/redis/6379.conf,将daemonize no修改为yes@H_301_7@
@H_301_7@
12.复制redis_init_script配置文件,重命名为redisd@H_301_7@
cp /usr/local/redis-4.0.2/utils/redis_init_script/etc/init.d/redisd@H_301_7@
@H_301_7@
13.修改配置文件redisd，第二行加上chkconfig: 2345 90 10。2345是运行级别，90表示启动的优先级，10表示停止的优先级@H_301_7@
#!/bin/sh
#chkconfig: 2345 90 10
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.@H_301_7@
@H_301_7@
14.配置开机自启动@H_301_7@
chkconfig redisd on@H_301_7@
15 启动与停止redis
@H_301_7@
systemctl start redisd.service@H_301_7@
systemctl stop redisd.service @H_301_7@
