如何用Systemd管理 general 包安裝的MySQL呢?
首先看看yum安裝的MySQL提供的Systemd管理指令碼
$ cat /usr/lib/systemd/system/mysqld.service # # Simple MySQL systemd service file # # systemd supports lots of fancy features, look here (and linked docs) for a full list: # http://www.freedesktop.org/software/systemd/man/systemd.exec.html # # Note: this file ( /usr/lib/systemd/system/mysql.service ) # will be overwritten on package upgrade, please copy the file to # # /etc/systemd/system/mysql.service # # to make needed changes. # # systemd-delta can be used to check differences between the two mysql.service files. # [Unit] Description=MySQL Community Server After=network.target After=syslog.target [Install] WantedBy=multi-user.target Alias=mysql.service [Service] User=mysql Group=mysql # Execute pre and post scripts as root PermissionsStartOnly=true # Needed to create system tables etc. ExecStartPre=/usr/bin/mysql-systemd-start pre # Start main service ExecStart=/usr/bin/mysqld_safe # Don't signal startup success before a ping works ExecStartPost=/usr/bin/mysql-systemd-start post # Give up if ping don't get an answer TimeoutSec=600 Restart=always PrivateTmp=false
適當修改 /lib/systemd/system/mysqld.service 如下:
After=network.target After=syslog.target [Install] WantedBy=multi-user.target Alias=mysql.service [Service] User=mysql Group=mysql PermissionsStartOnly=true ExecStart=/usr/local/mysql/bin/mysqld_safe TimeoutSec=600 Restart=always PrivateTmp=false
然後
ln -s /lib/systemd/system/mysqld.service /etc/systemd/mysqld.service
ln -s /lib/systemd/system/mysqld.service /etc/systemd/mysqld.service
然後 使用 systemctl 設定 mysqld.service自動啟動
systemctl enable mysqld.service
檢視是否設定成:
systemctl 常見用法:
開機啟動:
systemctl enable ***.service
停止開機啟動:
systemctl disable ***.service
啟動/停止/重啟服務:
systemctl start/stop/restart ***.service
查詢服務狀態:
systemctl status ***.service
列出系統服務,-t後用tab鍵可以關聯出所有支援的unit型別
查詢某項服務是否active,以sshd.serice為例
systemctl is-active sshd.service
直接檢視某項服務的配置檔案,以mysqld.serice為例
檢視環境變數
