zabbix4.4 启动失败分析

zabbix是基于WEB界面提供分布式系统监视以及网络监视功能的企业级开源解决方案，能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。
做为开源用户的支持者，我们大部分环境用的软件包含监控软件、数据库、继承应用、操作系统等都是用开源的，例如centos、PG、zabbix、openshift等，但是开源的在成熟度上是不错，但是安装软件有时比较麻烦，例如centos的安全开关，默认情况下会导致我们在安装openshift、zabbix等导致失败，而错误日志提示往往与实际十万三千里，但是有经验的在安装完系统后会有意识性的去修改配置，避免不必要的问题，
如下问题：

在安装配置好zabbix后无法正常启动，原因是SELINUX设置问题导致启动失败，
故障分析：
[root@localhost zabbix]# systemctl start zabbix-server.service
Job for zabbix-server.service failed because a configured resource limit was exceeded. See "systemctl status zabbix-server.service" and "journalctl -xe" for details.

查看 zabbix 日志分析：
发现日志提示权限问题：

5966:20200107:145500.376 using configuration file: /etc/zabbix/zabbix_server.conf

5976:20200107:145506.314 Starting Zabbix Server. Zabbix 4.4.4 (revision 3131fdac04

问题根源分析：

[root@localhost logs]# getenforce
Enforcing------这时发现selinux的配置是Enforcing
[root@localhost logs]# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
[root@localhost logs]# cd /etc/selinux
[root@localhost selinux]# ls
config final semanage.conf targeted tmp

直接把selinux 关掉如下：
[root@localhost selinux]# vi 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

优化修改SELINUX=disabled

重新启动：

[root@localhost ~]# systemctl start zabbix-server.service
[root@localhost ~]# systemctl status zabbix-server.service
● zabbix-server.service - Zabbix Server

因此，一般在安装一些开源软件，如MYSQL、POSTGRES、zabbix、openshift等，在安装前先检查下系统对应版本是否与需安装的软件兼容性、在检查下下，防火墙、安全等是否开启，如下：
1、iptables开启和关闭
2、SELinux开启和关闭
3、CentOS 6和CentOS 7 firewalld防火墙的开与关等
