Question

我安装了Centos 7,64位。安装postgresql-9.4。使用命令

初始化postgresql

/usr/pgsql-9.4/bin/postgresql94-setup initdb

然后使用此命令启动postgresql

systemctl start postgresql-9.4

并显示如下错误：

service failed because the control process exited with error code. See "systemctl status postgresql-9.4.service" and "journalctl -xe" for details.

输入命令

systemctl status postgresql-9.4.service
● postgresql-9.4.service - PostgreSQL 9.4 database server

Answer 1

1 - 安装psmisc软件包以在Postgres上提供killall

#yum install psmisc

2 - 执行杀戮

＃killall -9 postgres

3 - 开始/停止

#systemctl stop postgresql- 9.4
#systemctl start postgresql- 9.4

4 - 检查服务是否正在执行，

＃ps -aux | grep postgres

centos 7 postgresql无法启动
