zabbix-agent 启动失败

安装完zabbix-agent以后启动失败，提示内容如下：

[root@proxyserver ~]# systemctl status zabbix-agent.service
● zabbix-agent.service - Zabbix Agent
   Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled)
   Active: activating (auto-restart) (thawing) (Result: protocol) since Thu 2022-09-01 11:40:27 CST; 162ms ago
  Process: 48867 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS)

检查Selinux配置

确认getenforce的输出结果是否为disabled，

[root@proxyserver zabbix]# getenforce 
Enforcing

如果不是disable，则临时关闭selinux

[root@proxyserver zabbix]# setenforce 0

此时尝试启动zabbix-agent

[root@proxyserver zabbix]# systemctl start zabbix-agent

若能正常启动，则将selinux永久关闭，即将 SELINUX=enforcing 。

[root@proxyserver zabbix]# 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=enforcing
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

[root@proxyserver zabbix]# vi /etc/selinux/config
[root@proxyserver zabbix]# cat /etc/selinux/config
