Galaxy Kirin desktop operating system installation postgresql13 (source code installation)

1、 First download the source code postgres

wget http://ftp.postgresql.org/pub/source/v13.1/postgresql-13.1.tar.bz2

2、 decompression

tar xjvf  postgresql-13.1.tar.bz2

3、 Enter folder

cd postgresql-13.1/

4、 Create installation path , Generally, we install it in /opt/ Under the folder
You have to use it here root Users to create

sudo su
mkdir -p /opt/pgsql-13.1

After creation, it must be root:root user ： User group

5、 To configure

./configure --prefix=/opt/pgsql-13.1 --without-readline

6、 compile

make -j8

7、 install

make install

Next is the point ：
We're going to create a linux user postgres, To start postgres service , As follows ：
1、 establish postgres user

# Sign in root user 
sudo su
# Add users 
useradd postgres
# Add password 
passwd postgres

2、 After the user is created, you can set just /opt/pgsql-13.1 User attribute of

# First, create a folder , As the data storage point of the database 
sudo su
mkdir /opt/pgsql-13.1/data
chown -R postgres /opt/pgsql-13.1

3、 Set the environment variable

sudo su
vim /etc/profile

Add... After opening at the end

PATH=$PATH:/opt/pgsql-13.1/bin
export PATH
LD_LIBRARY_PATH=/opt/pgsql-13.1/lib
export LD_LIBRARY_PATH
export PGDATA=/opt/pgsql-13.1/data

4、 After adding source once

source /etc/profile

5、 Get into postgres

su - postgres

Be careful , At this time, there is only one command line $ Symbol , We just need to type bash After that, we can

bash
ls -l
postgres --version
initdb
pg_ctl start
psql -h 127.0.0.1

Login as follows

[email protected]-D2000:/opt/pgsql-13.1$ psql -h 127.0.0.1 
psql (12.9 (Ubuntu 12.9-0kylin0.20.04.1k1),  The server  13.1)
 Warning ：psql  Main version 12, The main version of the server is 13.
      some psql The function may not work properly .
 Input  "help"  For help .

postgres=#

You can create database users and database 了 .
Create user

postgres=# create user username with password '****';
CREATE ROLE
postgres=#

Create database

postgres=# create database dbtest owner username; --  Create the database and specify the owner 
CREATE DATABASE
postgres=#

Set the permissions of the database , All assigned to a user

postgres=# grant all on database dbtest to username; --  take dbtest All permissions are assigned to username
GRANT
postgres=#

After creation, you can exit

postgres=#\q

So much work ahead is mainly to prepare for the next , other linux User login database

psql -h 10.10.10.10 -U user -d postgres -p 5432

-h： database IP
-U： The logged in user
-d： Login database
-p： Login port

So you can be in Linux Use your usual Linux Log in to the database

[email protected]:~$ psql -U shenyan -d shenyan_f -h 127.0.0.1
psql (12.9 (Ubuntu 12.9-0kylin0.20.04.1k1),  The server  13.1)
 Warning ：psql  Main version 12, The main version of the server is 13.
      some psql The function may not work properly .
 Input  "help"  For help .

shenyan_f=> 

Be careful ：
It is worth noting that posgres The database service must be Linux postgres user , This is a postgres Database default , So you don't create this user ,postgres The service itself will also be created , After he created it, the password was randomly generated , We can't know , So I can't log in postgres, So let's create it manually .

If you feel troublesome, just adopt docker

[[email protected] ~]# docker pull postgres #  Load image 

[[email protected] ~]# docker run \
--name demo \
--privileged=true \
-e TZ='Asia/Shanghai' \
-e POSTGRES_USER=koji \
-e POSTGRES_DB=koji \
-e POSTGRES_PASSWORD=123456 \
-e PGDATA=/tmp/ \
-v /root/data:/tmp/ \
-p 5432:5432 \
-v /root/pem/psql-run:/docker-entrypoint-initdb.d \
-d \
postgres

Then you can log in to the database , After logging in, you can create your own database user and database .
Because we have mapped data, So as long as /root/data stay , Even if the database docker Deleted , After next startup , There are still data .
