cannot open PID file [/tmp/zabbix_agentd.pid]: [13] Permission denied 权限拒绝 很直观就是权限的问题

我的问题是这样的，这个pid文件是我安装了两个zabbix 之前一个生成的pid 直接删除pid 搞定

2 no active checks on server [127.0.0.1:10051]: host [0022] not found
21270:20170226:112109.911 failed to accept an incoming connection: connection from "192.168.199.222" rejected, allowed hosts: "127.0.0.1"

出现该错误的原因是一般是zabbix_agentd.conf里面的Hostname和前端zabbix web里面的配置不一样所造成的，即在zabbix web页面Monitoring->Configuration->Hosts 页面的Name和zabbix_agentd.conf里面的Hostname要一样。 

解决方法：

1.查看zabbix_agentd.conf文件中的Hostname

# cat zabbix_agentd.conf | grep Hostname
### Option: Hostname
# Value is acquired from HostnameItem if undefined.
# Hostname=
Hostname=127.0.0.1
### Option: HostnameItem
# Item used for generating Hostname if it is undefined. Ignored if Hostname is defined.
# HostnameItem=system.hostname
# Aliases can be used in HostMetadataItem but not in HostnameItem parameters.

# Aliases can be used in HostMetadataItem but not in HostnameItem parameters. 

2.在zabbix web页面Monitoring->Configuration->Hosts 页面更改Host name和zabbix_agentd.conf里面的Hostname一样。 

3.杀死进程重新启动zabbix-agent服务

ps -ef | grep zabbix_agentd |grep -v grep xargs -i{} kill -9 {}    && ../sbin/zabbix_agentd 

4.再次查看日志文件

tail -f /tmp/zabbix_agentd.log
