# yum安装gcc依赖
yum install gcc
切换到redis-5.0.2
[root@sitaird01 ~]# cd redis-5.0.2/
# 编译并安装
[root@sitaird01 redis-5.0.2]# make MALLOC=libc
[root@sitaird01 redis-5.0.2]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)

# 测试是否安装成功
先切换到redis src目录下
[root@sitaird01 redis-5.0.2]# cd src/
1、直接启动redis
[root@sitaird01 src]# ./redis-server

# 以后台进程方式启动redis
第一步：修改redis.conf文件
[root@sitaird01 redis-5.0.2]# vim /root/redis-5.0.2/redis.conf
daemonize no
bind 127.0.0.1
修改为
daemonize yes
bind 0.0.0.0
第二步：指定redis.conf文件启动
[root@sitaird01 src]# ./redis-server /root/redis-5.0.2/redis.conf
第三步：关闭redis进程
首先使用ps -aux | grep redis查看redis进程
[root@sitaird01 src]# ps -aux | grep redis
root 21714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 0.0.0.0:6379
root 1119 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
使用kill命令杀死进程
[root@sitaird01 src]# kill -9 21714
第七步：设置redis开机自启动
1、在/etc目录下新建redis目录
[root@sitaird01 src]# mkdir /etc/redis
2、将/root/redis-5.0.2/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf
[root@sitaird01 src]# cp /root/redis-5.0.2/redis.conf /etc/redis/6379.conf
3、将redis的启动脚本复制一份放到/etc/init.d目录下
[root@sitaird01 src]# cp /root/redis-5.0.2/utils/redis_init_script /etc/init.d/redis
4、设置redis开机自启动
先切换到/etc/init.d目录下
[root@sitaird01 src]# chkconfig redis on
如果提示redisd不支持chkconfig
service redisd does not support chkconfig
解决方法：
使用vim编辑redisd件，在第一行加入如下两行注释，保存退出
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。
再次执行开机自启命令，成功
1
[root@sitaird01 redis-5.0.2]# chkconfig redisd on
现在可以直接已服务的形式启动和关闭redis了
启动：
[root@sitaird01 redis-5.0.2]# systemctl start redis
[root@sitaird01 redis-5.0.2]# systemctl status redis
