无法在 CentOS 7 上启动 postgresql-9.5。
我关注了这个页面 -https://wiki.postgresql.org/wiki/YUM_Installation https://wiki.postgresql.org/wiki/YUM_Installation- 用于在 CentOS 上安装数据库服务器。
设置后我也尝试了同样的操作setenforce 0，这也没有帮助。
我正在做所有操作root.
systemctl start postgresql-9.5.service
Job for postgresql-9.5.service failed because the control process exited with error
code. See "systemctl status postgresql-9.5.service" and "journalctl -xe" for details.
这是我得到的状态 -
Redirecting to /bin/systemctl status postgresql-9.5.service

谷歌搜索我看到的错误。
许多人都遇到过同样的错误，但每种情况的根本原因都不同。通读这些帖子，我不清楚我是否看到了任何已经报告的原因。
确保您已正确安装所有软件包并更新 yum 存储库部分[base] and [updates]在安装之前，如其中提到的guide https://wiki.postgresql.org/wiki/YUM_Installation。我们有 CentOS 7 和 PostgreSQL 9.5，通过以下步骤它可以完美运行：
vi /etc/yum.repos.d/CentOS-Base.repo
yum localinstall http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm
yum list postgres*
yum install -y postgresql95-server.x86_64 postgresql95-contrib.x86_64 postgresql95-libs.x86_64
/usr/pgsql-9.5/bin/postgresql95-setup initdb
systemctl enable postgresql-9.5.service
systemctl start postgresql-9.5.service
最后，systemctl status postgresql-9.5.service应该向你展示这样的东西：
