把redis设置为系统服务
以下是在Linux系统上使用systemctl配置redis检查的步骤:
1. 在/etc/systemd/system目录下创建一个名为redis.service的文件,例如:
```
sudo nano /etc/systemd/system/redis.service
```
2. 在文件中添加以下内容:
```
[Unit]
Description=Redis In-Memory Data Store
After=network.target
[Service]
User=redis
Group=redis
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/local/bin/redis-cli shutdown
Restart=always
[Install]
WantedBy=multi-user.target
```
3. 保存并关闭文件。
4. 然后重新加载systemctl配置:
```
sudo systemctl daemon-reload
```
5. 启动Redis服务:
```
sudo systemctl start redis
```
6. 检查Redis服务是否正在运行:
```
sudo systemctl status redis
```
如果Redis正在运行,您应该看到类似以下内容的输出:
```
● redis.service - Redis In-Memory Data Store
Loaded: loaded (/etc/systemd/system/redis.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2021-07-16 15:32:46 UTC; 3s ago
Main PID: 1234 (redis-server)
…
```
7. 最后,配置检查Redis服务的systemctl定时器:
```
sudo nano /etc/systemd/system/redis-check.service
```
8. 添加以下内容:
```
[Unit]
Description=Redis Check Timer
[Timer]
OnBootSec=10s
OnUnitActiveSec=1m
Unit=redis.service
[Install]
WantedBy=timers.target
```
9. 保存并关闭文件。
10. 重新加载systemctl配置:
```
sudo systemctl daemon-reload
```
11. 启动Redis检查定时器:
```
sudo systemctl start redis-check.timer
```
12. 确认定时器正在运行:
```
sudo systemctl status redis-check.timer
```
现在,每分钟systemd将检查一次Redis服务是否在运行状态。如果检测到Redis未在运行,则会自动重新启动服务。
