# 測試是否安裝成功 
先切換到redis src目錄下

[email protected] redis-5.0.2]# cd src/
1、直接啟動redis
[[email protected] src]# ./redis-server

# 以後臺程序方式啟動redis
第一步：修改redis.conf檔案
[[email protected] redis-5.0.2]# vim /root/redis-5.0.2/redis.conf 

daemonize no
bind 127.0.0.1　　
修改為
daemonize yes
bind 0.0.0.0
　　
第二步：指定redis.conf檔案啟動
[[email protected] src]# ./redis-server /root/redis-5.0.2/redis.conf
 

第三步：關閉redis程序

首先使用ps -aux | grep redis檢視redis程序
[[email protected] 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命令殺死程序
[[email protected] src]# kill -9 21714
　　

　　　

 

第七步：設定redis開機自啟動

1、在/etc目錄下新建redis目錄
[[email protected] src]# mkdir /etc/redis
 
2、將/root/redis-5.0.2/redis.conf  檔案複製一份到/etc/redis目錄下，並命名為6379.conf　　
[[email protected] src]# cp /root/redis-5.0.2/redis.conf /etc/redis/6379.conf
　　

3、將redis的啟動指令碼複製一份放到/etc/init.d目錄下
[[email protected] src]# cp /root/redis-5.0.2/utils/redis_init_script /etc/init.d/redis
　　

4、設定redis開機自啟動
先切換到/etc/init.d目錄下
[[email protected] src]# chkconfig redis on

如果提示redisd不支援chkconfig
service redisd does not support chkconfig　

解決方法：
使用vim編輯redisd件，在第一行加入如下兩行註釋，儲存退出
# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database
註釋的意思是，redis服務必須在執行級2，3，4，5下被啟動或關閉，啟動的優先順序是90，關閉的優先順序是10。

再次執行開機自啟命令，成功

1
[[email protected] redis-5.0.2]#  chkconfig redisd on
　　

現在可以直接已服務的形式啟動和關閉redis了

啟動：
[[email protected] redis-5.0.2]# systemctl start   redis 
[[email protected] redis-5.0.2]# systemctl status  redis
