1. 安装前的准备

   yum install \
   vim \
   wget \
   firewalld \
   gcc \
   gcc-c++ \
   openssl-devel \
   readline \
   readline-devel \
   zlib \
   zlib-devel \
   uuid-devel \
   systemd-devel \
    -y \

2. 安装PostGreSQL

   cd /home

   --with-ossp-uuid \
   --with-uuid=ossp \
   --with-systemd \
   --with-openssl \
   
   make
   make install

3. 添加postgres用户并配置数据目录

   mkdir /data/
   mkdir /data/postgres/
   
   useradd postgres
   
   chown -R postgres:postgres /data/postgres/
   chown -R postgres:postgres /usr/local/postgres/
   chown -R postgres:postgres /home/postgresql-10.3/

4. 配置启动防火墙

   systemctl start firewalld
   firewall-cmd --zone=public --add-port=5432/tcp --permanent
   firewall-cmd --reload

5. 修改环境变量

   vim /etc/profile
   
   export PGHOME=/usr/local/postgres
   export PGDATA=/data/postgres
   export PATH=$PATH:/usr/local/postgres/bin
   
   ESC
   :wq
   
   source /etc/profile

6. 初始化数据库

   su postgres
   /usr/local/postgres/bin/initdb -D /data/postgres

7. 修改配置

   su postgres
   vim /data/postgres/pg_hba.conf
   
   local   all             all                                     trust
   host    all             all             127.0.0.1/32            trust
   host    all             all             0.0.0.0/0               trust
   host    all             all             ::1/128                 trust
   
   local   replication     all                                     trust
   host    replication     all             127.0.0.1/32            trust
   host    replication     all             0.0.0.0/0               trust
   host    replication     all             ::1/128                 trust
   
   ESC
   :wq
   
   vim /data/postgres/postgresql.conf
   
   listen_addresses = '*'
   
   ESC
   :wq

8. 启动

   su postgres
   /usr/local/postgres/bin/pg_ctl -D /data/postgres -l logfile start

9. 创建默认数据库及设置密码

   su postgres
   /usr/local/postgres/bin/createdb postgres
   /usr/local/postgres/bin/psql postgres
   # 已经进入了postgres控制台
   \password
   # 接下来输入密码
   **************
   # 退出
   \q

10. 停止、启动、重启、重载

    su postgres
    /usr/local/postgres/bin/pg_ctl -D /data/postgres -l logfile stop
    /usr/local/postgres/bin/pg_ctl -D /data/postgres -l logfile start
    /usr/local/postgres/bin/pg_ctl -D /data/postgres -l logfile restart
    /usr/local/postgres/bin/pg_ctl -D /data/postgres -l logfile reload
