遇到一个问题 zabbix-agent 一直启动不起来
查看Zabbix Agent日志文件才究其原因。
tail /var/log/zabbix/zabbix_agentd.log

[root@localhost run]# ll
drwxr-xr-x 2 root root 40 Aug 30 16:29 zabbix
进入 var/run 目录下， 查看到 文件夹zabbix 权限为 root ，需修改权限设定 所有者为 zabbix用户。
[root@localhost run]# chown -R zabbix.zabbix zabbix (或者 chmod 777 -R zabbix)
或者修改配置文件
vim /etc/zabbix/zabbix_agentd.conf
# Default:
PidFile=/tmp/zabbix_agentd.pid
#PidFile=/var/run/zabbix/zabbix_agentd.pid
[root@localhost run]# ll
drwxr-xr-x 2 zabbix zabbix 40 Aug 30 16:29 zabbix
此时重启zabbix-agent 服务 ， 可看到服务启动了
[root@localhost run]# systemctl restart zabbix-agent
[root@localhost run]# ps aux|grep zabbix

在 zabbix 服务器上做 测试
[root@zabbix ~]# zabbix_get -s 103.***.***. 174 -p 21224 -k system.hostname
localhost
