root@test-server03:~# systemctl stop postgresql
root@test-server03:~# cd /etc/postgresql/10/main/
root@test-server03:/etc/postgresql/10/main# vim postgresql.conf
#修改下面参数为自己的数据盘目录
data_directory = '/opt/postgresql/data'

3. 创建数据目录并授权

root@test-server03:/etc/postgresql/10/main# mkdir /opt/postgresql/data -p
root@test-server03:/etc/postgresql/10/main# chown -R postgres.postgres /opt/postgresql*

4. 初始化数据库

#找到initdb的位置
root@test-server03:~# find / -name initdb
/usr/lib/postgresql/10/bin/initdb
#初始化
root@test-server03:~# sudo -u postgres /usr/lib/postgresql/10/bin/initdb -D /opt/postgresql/data
#重新启动postgresql
root@test-server03:~# systemctl restart postgresql

5. 修改postgres用户密码
