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，上传安转包后按照目录规划安装 postgre 数据库。
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@rhel6 postgres]# chmod -R 777 pgsql
[root@rhel6 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cd /home/postgres/pgsql/bin
/home/pg/postgres/pgsql/bin/initdb -D /home/postgres/data/ eg:
[postgres@rhel6 bin]$ ./initdb -D /home/postgres/data/
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 "en_US.UTF-8". The default database encoding has accordingly been set to "UTF8". The default text search configuration will be set to "english".
Data page checksums are disabled.

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 /home/postgres/data/ -l logfile start
6)启动数据库
./pg_ctl -D /home/postgres/data/ -l logfile start
eg:
[postgres@rhel6 bin]$ ./pg_ctl -D /home/postgres/data/ -l logfile start

server started
7)停止数据库
./pg_ctl -D /home/postgres/data/ stop
