  • Centos7下源编译安装Postgresql 并设置开机自动启动postgresql.serivce 服务相关研究

    编写开机自动启动服务脚本:

    # cat >> /usr/lib/systemd/system/postgresql.service >> EOF

    [Unit]
    Description=PostgreSQL database server
    After=network.target
    
    [Service]
    Type=forking
    
    User=postgres
    Group=postgres
    
    # Port number for server to listen on
    Environment=PGPORT=5432
    
    # Location of database directory
    Environment=PGDATA=/usr/local/pgsql9.4/data
    
    # Where to send early-startup messages from the server (before the logging 
    # options of postgresql.conf take effect) 
    # This is normally controlled by the global default set by systemd
    # StandardOutput=syslog
    
    # Disable OOM kill on the postmaster
    OOMScoreAdjust=-1000
    
    #ExecStartPre=/usr/local/pgsql9.4/bin/postgresql-check-db-dir ${PGDATA}
    ExecStart=/usr/local/pgsql9.4/bin/pg_ctl start -D ${PGDATA} -s -o "-p ${PGPORT}" -w -t 300
    ExecStop=/usr/local/pgsql9.4/bin/pg_ctl stop -D ${PGDATA} -s -m fast
    ExecReload=/usr/local/pgsql9.4/bin/pg_ctl reload -D ${PGDATA} -s
    
    # Give a reasonable amount of time for the server to start up/shut down
    TimeoutSec=300
    
    [Install]
    WantedBy=multi-user.target

    EOF

    添加可执行权限:

    chmod 754 /usr/lib/systemd/system/postgresql.service
    

    设置为开机自启动:

    systemctl enable postgresql.service
    

    常用指令(以postgresql服务为例):

    启动某服务: 

    systemctl  start  postgresql.service

    停止某服务:

    systemctl stop postgresql.service

    重启某服务:

    systemctl restart postgresql.service
    service postgresql restart

    使某服务自动启动(如tomcat服务):

    systemctl enable postgresql.service

    使某服务不自动启动:

    systemctl disable postgresql.service

    检查服务状态:

    systemctl   status  postgresql.service (服务详细信息)
    systemctl   is-active postgresql.service(仅显示是否Active)

    显示所有已启动的服务:

    systemctl   list-units --type=service
