[转帖]在麒麟linux上安装Postgresql12.5

https://jimolonely.github.io/tech/linux/install-postgresql-kylin/

本文主要实践在麒麟V10版本上通过源码编译安装PostgreSQL12.5，因为是源码编译，所以对于其他版本也具有参考性。

麒麟版本

V10

$ uname -a
Linux kylin-v10-02 4.19.90-24.4.v2101.ky10.aarch64 #1 SMP Mon May 24 14:45:37 CST 2021 aarch64 aarch64 aarch64 GNU/Linux

下载PostgreSQL12.5源码

下载地址为官网：https://www.postgresql.org/ftp/source/v12.5/

上传解压到服务器。

编译源码过程

官方文档.

运行

./configure

得到如下报错：

error: readline library not found

需要安装readline

yum install readline-devel -y

然后再运行 ./configure

没有报错后，再运行

make

编译完成后得到成功提示

然后开始安装, 运行

make install

安装成功后可以看到

默认安装路径为 /usr/local/pgsql，我们需要将权限改为postgres

[root@kylin-v10-02 local]# useradd postgres
[root@kylin-v10-02 local]# chown -R postgres:postgres /usr/local/pgsql/

配置环境变量

安装完成后，还要做一些配置操作.

vim /etc/profile加入下面的环境变量配置

export PATH=/usr/local/pgsql/bin:$PATH

LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH

然后刷新配置：

source /etc/profile

启动服务

在启动PG之前，需要准备一个数据目录，注意修改权限：

mkdir -p /export/pgdata
chown -R postgres:postgres /export/pgdata

初始化数据库，注意，要切换到postgres用户

# sudo su - postgres
initdb -D /export/pgdata/

完整输出如下：

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "zh_CN.UTF-8".
The default database encoding has accordingly been set to "UTF8".
initdb: could not find suitable text search configuration for locale "zh_CN.UTF-8"
The default text search configuration will be set to "simple".

Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    pg_ctl -D /export/pgdata/ -l logfile start

启动PG

那我们就启动服务：

[postgres@kylin-v10-02 ~]$ pg_ctl -D /export/pgdata/ -l logfile start
waiting for server to start.... done
server started

测试

[postgres@kylin-v10-02 ~]$ psql
psql (12.5)
Type "help" for help.

postgres=# \l
List of databases
Name    |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
postgres  | postgres | UTF8     | zh_CN.UTF-8 | zh_CN.UTF-8 |
template0 | postgres | UTF8     | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgres          +
|          |          |             |             | postgres=CTc/postgres
template1 | postgres | UTF8     | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgres          +
|          |          |             |             | postgres=CTc/postgres
(3 rows)

测试ok，不过要提供给其他机器用，还需要一些监听和安全配置。

修改密码

postgres=# alter user postgres password 'postgres';
ALTER ROLE

修改监听地址

默认情况是在localhost上监听 vim /export/pgdata/postgresql.conf ，修改监听地址

listen_addresses = '*'

还要允许密码访问，vim /export/pgdata/pg_hba.conf，在最后加入：

host  all  all 0.0.0.0/0 md5

然后重启服务

pg_ctl -D /export/pgdata/ -l logfile restart
