MySQL Router如何配置成systemd服务自启与异常中止后自愈？

1. mysqlrouter.service配置文件， -c 指定router的配置文件，Restart=on-failure
服务异常奔溃后自愈

cat   /usr/lib/systemd/system/mysqlrouter.service

[Unit]
Description=Percona MySQL Router
After=network.target
After=syslog.target


[Service]
Type=notify
User=mysqlrouter
Group=mysqlrouter

# Start main service
ExecStart=/usr/bin/mysqlrouter -c /var/lib/mysqlrouter/mysqlrouter.conf

# Sets open_files_limit
LimitNOFILE = 100000

Restart=on-failure

PrivateTmp=true

[Install]
WantedBy=multi-user.target

​

2、mysqlrouter配置主机重启后服务自启

[root@test_cdh_001 ~]# systemctl enable mysqlrouter
[root@test_cdh_001 ~]# 
[root@test_cdh_001 ~]# systemctl is-enabled mysqlrouter
enabled
