How to set PostgreSQL startup on Ubuntu 16.04

Since PostgreSQL is compiled and installed, it needs to be set to boot. For the Ubuntu system, it is slightly different from systems like Red Hat.

First, the first step, because we are used to using systems like Red Hat, we need to get a chkconfig out. This command is a command to configure the Red Hat service to start and stop, but it is not available on Ubuntu. We can use sysv-rc-conf.

sudo apt install sysv-rc-conf

After installing sysv-rc-conf, we replaced it with chkconfig. After all, this command is too difficult to remember.

sudo cp /usr/sbin/sysv-rc-conf /usr/sbin/chkconfig

Next we can try to use the chkconfig command to view

After this is done, we need to go to the /postgresql-10.3/contrib/start-scripts directory of the PostgreSQL installation compressed package. There are several system configuration files under the directory. We use Ununtu here and choose linux and copy this file to /etc/init.d/. And give executable x permission.

postgres@postgres-N65S01:~/postgresql-10.3/contrib/start-scripts$ ls
freebsd linux macos osx
postgres@postgres-N65S01:~/sudo cp linux /etc/init.d/
postgres@postgres-N65S01:/etc/init.d$sudo mv linux postgresql-10.0
postgres@postgres-N65S01:/etc/init.d$chmod a+x postgresql-10.0

After doing the above operations, you need to modify the file, mainly modify the following two locations

The prefix is the postgreSQL installation directory, and PGDATA is the directory where the database files are located. Save after modification. Execute the following command to set the service to start automatically.

postgres@postgres-N65S01:/etc/init.d$ sudo chkconfig postgresql-10.0 on
postgres@postgres-N65S01:/etc/init.d$ sudo chkconfig --list | grep postgres
postgresql-12:on 3:on 4:on 5:on

After restarting the host again, you can find that the postgreSQL database can be started automatically.

postgres@postgres-N65S01:/etc/init.d$ ps -ef | grep pgdata
postgres 24601019:19?00:00:00/opt/PostgreSQL-10/bin/postmaster -D /pgdata/data
postgres 46832853019:43 pts/1800:00:00 grep --color=auto pgdata
