PostgreSQL installation complete.

　　9、安装完成后可以看到在/usr/local目录上成了pgsql-10.5目录

[root@web1 postgresql-10.5]# ll /usr/local/ |grep pgsql-10.5
drwxr-xr-x  6 root root  56 May 23 18:06 pgsql-10.5
[root@web1 postgresql-10.5]#

　　10、创建用户及设置/usr/local/pgsql-10.5目录文件属主组

[root@web1 postgresql-10.5]# useradd postgres
[root@web1 postgresql-10.5]# chown -R postgres.postgres /usr/local/pgsql-10.5/
[root@web1 postgresql-10.5]# ll /usr/local/ |grep pgsql-10.5
drwxr-xr-x  6 postgres postgres  56 May 23 18:06 pgsql-10.5
[root@web1 postgresql-10.5]#

　　11、给/usr/local/pgsql-10.5目录设置软连接（方便查看和管理吧....）

[root@web1 postgresql-10.5]# ln -s /usr/local/pgsql-10.5/ /usr/local/pgsql
[root@web1 postgresql-10.5]# ll /usr/local/pgsql
lrwxrwxrwx 1 root root 22 May 23 18:15 /usr/local/pgsql -> /usr/local/pgsql-10.5/
[root@web1 postgresql-10.5]#

　　12、进入刚创建的postgres用户

[root@web1 postgresql-10.5]# su postgres
[postgres@web1 postgresql-10.5]$

　　13、设置环境变量（注意路径）

[postgres@web1 ~]$ vim ~/.bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH=$PATH:/usr/local/pgsql-10.5/bin
PGDATA=/usr/local/pgsql-10.5/data
export PGDATA
export PATH

　　14、当前生效

[postgres@web1 ~]$ source ~/.bash_profile
[postgres@web1 ~]$

　　15、测试

[postgres@web1 ~]$ which psql
/usr/local/pgsql-10.5/bin/psql
[postgres@web1 ~]$ psql -V
psql (PostgreSQL) 10.5

　　16、初始化数据库（initdb --help查看讲情），指定库文件路径

[postgres@web1 ~]$ initdb /usr/local/pgsql-10.5/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.
