今天在节点机器上新安装的Zabbix Agent无法启动。

1.查看Zabbix Agent日志文件才究其原因。

# cat /var/log/zabbix/zabbix_agentd.log

2.此时只需要关闭Selinux，两种方案；

2.1.临时关闭

# setenforce 0

2.2.永久关闭（reboot host）

# vim /etc/selinux/config

SELINUX=enforcing

改

SELINUX=disabled

3.操作完成后，再次启动zabbix-agent服务

# systemctl start zabbix-agent.service

4.查看端口

# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port 
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:* 
LISTEN 0 128 *:10050 *:*
LISTEN 0 80 :::3306 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*
LISTEN 0 128 :::10050 :::*

zabbix agent启动成功，10050端口已经运行。
