How to set up PostgreSQL startup on Ubuntu 16.04

Since PostgreSQL is compiled and installed, you need to set it to start at boot. For Ubuntu systems, it is slightly different from systems like Red Hat.

The first step is that since we are used to using systems like Red Hat, we need to create a chkconfig. This command is used to configure the start and stop of Red Hat services, 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 replace 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. Since we are using Ununtu here, we choose linux and copy this file to /etc/init.d/. And grant 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 completing the above operations, you need to modify the file, mainly modify the following two locations

prefix is ​​the postgreSQL installation directory, and PGDATA is the directory where the database file is 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-1 2: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 2460 1 0 19:19 ? 00:00:00 /opt/PostgreSQL-10/bin/postmaster -D /pgdata/data
postgres 4683 2853 0 19:43 pts/18 00:00:00 grep --color=auto pgdata
