关闭SELinux
[root@postgis postgresql]# setenforce 0
[root@postgis postgresql]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@postgis postgresql]# 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 values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted文件最大打开数限制
# linux资源限制配置文件是/etc/security/limits.conf；限制用户进程的数量对于linux系统的稳定性非常重要。
# limits.conf文件限制着用户可以使用的最大文件数，最大线程，最大内存等资源使用量
vim /etc/security/limit.conf
* soft nofile 655350 #任何用户可以打开的最大的文件描述符数量，默认1024，这里的数值会限制tcp连接
* hard nofile 655350
* soft nproc 655350 #任何用户可以打开的最大进程数
* hard nproc 650000开放系统防火墙
# 添加防火墙规则
[root@postgis lib]# firewall-cmd --permanent --add-port=5432/tcp

Linux 2.6及以后版本中，可修改内核行为，使其不会“过量使用内存”。虽然不能阻止OOM发生，但可显著降低其发生的可能性。通过sysctl 选择严格的过量使用模式来实现：
sysctl -w vm.overcommit_memory=2
或者写入配置文件：
echo "vm.overcommit_memory=2" >> /etc/sysctl.confYUM安装
