Systemd postgresql 啟動腳本

我正在將 postgresql 安裝到第二台伺服器上

以前我安裝了 postgresql 然後使用提供的腳本

./contrib/start-scripts/linux

放入正確的目錄

# cp ./contrib/start-scripts/linux /etc/rc.d/init.d/postgresql92
# chmod 755 /etc/rc.d/init.d/postgresql92

然後我可以按預期執行

# service postgresql92 start

然而，新機器正在使用 Systemd，看起來有一種完全不同的方法可以做到這一點

我不想破解這個並破壞某些東西，所以我想知道是否有人可以指出我如何達到相同結果的正確方向

從源安裝時，您需要添加一個與源安裝一起使用的 systemd 單元文件。對於 RHEL，Fedora 我的單元文件如下所示：

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

[Unit]
Description=PostgreSQL database server
After=network.target

[Service]
Type=forking

User=postgres
Group=postgres

# 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
# ... but allow it still to be effective for child processes
# (note that these settings are ignored by Postgres releases before 9.5)
Environment=PG_OOM_ADJUST_FILE=/proc/self/oom_score_adj
Environment=PG_OOM_ADJUST_VALUE=0

# Maximum number of seconds pg_ctl will wait for postgres to start.  Note that
# PGSTARTTIMEOUT should be less than TimeoutSec value.
Environment=PGSTARTTIMEOUT=270

Environment=PGDATA=/usr/local/pgsql/data


ExecStart=/usr/local/pgsql/bin/pg_ctl start -D ${PGDATA} -s -w -t ${PGSTARTTIMEOUT}
ExecStop=/usr/local/pgsql/bin/pg_ctl stop -D ${PGDATA} -s -m fast
ExecReload=/usr/local/pgsql/bin/pg_ctl reload -D ${PGDATA} -s

# Give a reasonable amount of time for the server to start up/shut down.
# Ideally, the timeout for starting PostgreSQL server should be handled more
# nicely by pg_ctl in ExecStart, so keep its timeout smaller than this value.
TimeoutSec=300

[Install]
WantedBy=multi-user.target

然後在啟動時啟用服務並啟動 PostgreSQL 服務：

$ sudo systemctl daemon-reload # load the updated service file from disk
$ sudo systemctl enable postgresql
$ sudo systemctl start postgresql
