启动zabbix-server有如下报错：

以上只是粘贴了部分的错误日志。
造成上述原因是因为SELINUX启动
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: disabled
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
解决办法如下：
vim /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
修改SELINUX=disabled修改配置文件永久关闭。
setenforce 0：临时关闭SELINUX。
也可以设置SELINUX允许zabbix访问，也不是很麻烦，但是SELINUX基本用不到，所有这种方法如果你们想知道就自己搜索下吧，在这里就不过多陈述了。
