初始化数据库
[postgres@test2019030517 postgresql-10.5]$ initdb -D /usr/local/postgresql/data/
启动服务
pg_ctl -D /var/postgresql/data -l /var/postgresql/logs/logfile start
连接数据库
[postgres@test2019030517 postgresql-10.5]$ psql 
创建数据库 
postgres=# create database test; 
创建表
postgres=# create table t_user (id integer, name text); 
插入测试数据
postgres=# insert into t_user values (1,‘joke‘);
查询数据
postgres=# select * from t_user;
退出psql窗口
postgres-# \q

[postgres@test2019030517 postgresql-10.5]$ vim /usr/local/postgresql/data/postgresql.conf 
 60 listen_addresses = ‘*‘          # what IP address(es) to listen on;
 65 max_connections = 100                   # (change requires restart)

[postgres@test2019030517 postgresql-10.5]$ vim /usr/local/postgresql/data/pg_hba.conf 
#在文件的最下方加上下面的这句话
host    all         all         0.0.0.0/0             trust

# 切换root用户
su - root
# 防火墙 允许5432 端口

[root@test2019030517 postgresql-10.5]# su - postgres
[postgres@test2019030517 ~]$ pg_ctl -D /usr/local//postgresql/data/ -l /usr/local/postgresql/logs/logfile restart

[postgres@test2019030517 ~]$ pg_ctl -D /usr/local//postgresql/data/ -l /usr/local/postgresql/logs/logfile stop

切换到root用户
[postgres@test2019030517 ~]$ su root
找到解压后源码包里面的一个linux文件
[root@test2019030517 postgres]# chmod a+x /data/postgresql-10.5/contrib/start-scripts/linux
复制linux文件到/etc/init.d目录下，更名为postgresql
[root@test2019030517 postgres]# cp /data/postgresql-10.5/contrib/start-scripts/linux /etc/init.d/postgresql
