1、环境规划

目录名称 存放位置
Postgres 用户家目录 /home/postgres
软件存放目录 /home/soft
安装目录 /usr/local
数据目录 /home/postgres/data/

2、安装流程
2.1 解压安装
在操作系统安装完成后，按照表格规划目录。
1)安装部署参考文档
下载页:https://www.enterprisedb.com/download-postgresql-binaries
软件包:postgresql-10.7-2-linux-x64-binaries.tar.gz
2)创建 postgre 安装用户

useradd postgres
passwd postgres

3)创建 postgre 安装目录及数据目录

mkdir -p /home/postgres/data/
chown -R postgres:postgres  /home/postgres/data/
chmod -R 775 /home/postgres/data/

4)解压安装

tar -xvf postgresql-10.8-4-linux-x64-binaries.tar -C /home/postgres/
[root@leo postgres]# chmod -R 777 pgsql
[root@leo postgres]# ll
total 12
drwxrwxrwx 9 root root 4096 Apr 10 03:24 pgsql 
drwx------ 19 postgres postgres 4096 Apr 15 11:33 pgsql_data

5)初始化数据库

[postgres@leo bin]$cd /home/postgres/pgsql/bin
[postgres@leo bin]$ ./initdb -D /home/postgres/data/

The database cluster will be initialized with locale "en_US.UTF-8". The default database encoding has accordingly been set to "UTF8". The default text search configuration will be set to "english".
