redis custom systemctl management service

1. Preparation

Compile and install redis (my installation directory/usr/loacl/tool)

Connect redis-server and redis- cli move to the environment variable directory (/usr/loacl/bin); give execution permission

cp redis.conf to the configuration directory (/etc/redis/redis.conf) or make a soft connection; (I choose the former )

Note: For the corresponding directory and permissions, please refer to other requirements

2. Create systemctl service

When using service to manage services, it is in /etc/init. Create a script file in the d/ directory to manage the start and stop of the service. In systemctl, it is similar, but the file directory is different. Create a script file redis.service in the /lib/systemd/system directory with the contents inside. As follows:

[Unit]
Description=Redis
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecReload=/usr/local/bin/redis-server -s reload
ExecStop=/usr/local/bin/redis-server -s stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

[Unit] indicates that this is basic information

Description is a description

After is started after that service, usually after the network service is started

[Service] means here is the service information

ExecStart is the command to start the service

ExecReload is the command to restart the service

ExecStop is the command to stop the service

[Install] Indicates that this is installation related information

WantedBy In which way it is started: multi-user.target indicates that when the system is started in multi-user mode (default run level), this service Needs to be run automatically.

3. Refresh the configuration

The systemctl just configured needs to refresh the configuration to take effect

$ systemctl daemon-reload

4. Set the boot usage

Set the redis service to be enabled at boot

$ systemctl enable redis.service
