防火墙:开了以后需要各种设置,很可能造成各种外部的连接不成功,比如ftp、telnet、ssh…(有些问题并不是浮在表面,你根本不知道是防火墙的锅),简单起见云服务器可以关闭防火墙而使用容易配置的安全组。
SELinux:SELinux策略是白名单原则,需要非常清楚安装软件使用的权限才能配置好(配置麻烦不说,头疼的是你不知道需要什么权限),而Linux已经有了比较完善的Security Best Practice。在Linux上部署工具有更多的实践经验和可行方案去保证系统的安全,即便是没有SELinux,是故大家普遍选择关闭SELinux。
# 查看防火墙是否关闭,未关闭使用(systemctl stop firewalld) systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1) # 查看selinux状态,未关闭修改(SELINUX=disabled) cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
# 未设置 /etc/sysctl.conf /etc/security/limits.conf
添加组及用户是很重要的,很多操作必须在特定用户下执行,之前安装postgresql遇到很多这方面的坑,大家小心。

第二部分的配置文件没有进行修改,这部分要根据实际情况进行配置,本文旨在单机安装gp数据库,具体使用方法需要更多的学习。如有问题,留言讨论。
