Systemd 如何设置开机启动守护进程

权限：systemd有系统和用户区分；系统（/user/lib/systemd/system/）、用户（/etc/lib/systemd/user/）.一般系统管理员手工创建的单元文件建议存放在/etc/systemd/system/目录下面。

--------------------

1、在/usr/lib/systemd/system/ 目录下 创建对应service（例如我要设置 gogs 为开机启动和守护进程，那么就创建 gogs.service ）

切换目录

cd /lib/systemd/system

创建对应的service

vi gogs.service

编辑 service

[Unit]
    Description=Gogs
    After=network.target
    
    [Service]
    # Modify these two values and uncomment them if you have
    # repos with lots of files and get an HTTP error 500 because
    # of that
    ###
    #LimitMEMLOCK=infinity
    #LimitNOFILE=65535
    Type=forking
    User=gogs
    Group=gogs
    WorkingDirectory=/usr/local/git/gogs
    ExecStart=/bin/sh /usr/local/git/gogs/gogs.sh
    Restart=always
    Environment=USER=gogs HOME=/home/gogs
    
    # Some distributions may not support these hardening directives. If you cannot start the service due
    # to an unknown option, comment out the ones not supported by your version of systemd.
    #ProtectSystem=full
    #PrivateDevices=yes
    #PrivateTmp=yes
    #NoNewPrivileges=true
    
    [Install]
    WantedBy=multi-user.target

wq 保存退出

--------------------

2、加载配置，执行配置。

systemctl daemon-reload

systemctl enable gogs.service

systemctl start gogs.service

查看 sercvice 状态

systemctl status gogs.service

如果输出如下，那么恭喜你就完成了

--------------------

附上nexus和sonarqube的配置

[Unit]
    After=nertwork.target
    
    [Service]
    User=sonarqube
    Type=forking
    #EnvironmentFile=-/etc/profile
    ExecStart=/bin/sh -c '. /etc/profile ; /usr/local/java/sonarqube/sonarqube-7.7/bin/linux-x86-64/sonar.sh start'
    ExecStop=/bin/sh -c '. /etc/profile ; /usr/local/java/sonarqube/sonarqube-7.7/bin/linux-x86-64/sonar.sh stop'
    Restart=on-failure
    
    [Install]
    WantedBy=multi-user.target
    Alias=sonarqube.service

[Unit]
    After=nertwork.target
    
    [Service]
    User=nexus
    Type=forking
    ExecStart=/bin/sh -c '. /etc/profile ; /usr/local/java/nexus/nexus-3.16.2-01/bin/nexus start'
    ExecStop=/bin/sh -c '. /etc/profile ; /usr/local/java/nexus/nexus-3.16.2-01/bin/nexus stop'
    Restart=on-failure
    
    [Install]
    WantedBy=multi-user.target
    Alias=nexus
