Linux redis 添加systemctl服务的具体步骤

安装redis 服务省略,可自行百度

vi /lib/systemd/system/redis.service

[Unit]
Description=Redis
After=network.target

[Service]
Type=forking
ExecStart=/home/redis/bin/redis-server /home/redis/etc/redis.conf   #  替换自己安装路径
ExecReload=/home/redis/bin/redis-server -s reload  #  替换自己安装路径
ExecStop=/home/redis/bin/redis-server -s stop    #  替换自己安装路径
PrivateTmp=true

[Install]
WantedBy=multi-user.target

[root@escapp /home/redis]#systemctl enable redis.service
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
[root@escapp /home/redis]#
[root@escapp /home/redis]#systemctl status redis.service
● redis.service - Redis
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)
   Active: inactive (dead)

此时因为之前redis 是启动的,需要先 kill 掉

[root@escapp /home/redis]#kill -9 25943
[root@escapp /home/redis]#
[root@escapp /home/redis]#
[root@escapp /home/redis]#ps -ef|grep redis
root     30609 13430  0 10:48 pts/0    00:00:00 vi /lib/systemd/system/redis.service
root     31142 13430  0 10:51 pts/0    00:00:00 grep --color=auto redis
[root@escapp /home/redis]#kill -9 30609
[1]+  已杀死               vi /lib/systemd/system/redis.service
[root@escapp /home/redis]#

命令：

重启： systemctl restart redis.service

状态：systemctl status redis.service

停止：systemctl stop redis.service

启动：systemctl start redis.service

[root@escapp /home/redis]#systemctl status redis.service
