今天增加监控的机器，遇到了各种各样的错误的，但多数都是基本问题
windows基本原因：防火墙
linux基本原因：防火墙与Selinux
错误代码：
windows错误代码：
Get value from agent failed: cannot connect to [[192.168.6.8]:10050]: [4] Interrupted system call
[[email protected] ~]# zabbix_get -s 192.168.6.8 -p 10050 -k system.uname
zabbix_get [10567]: Timeout while executing operation
解决方法关闭防火墙，问题解决
linux错误代码：
1.[113] No route to host #防火墙原因
解决方法：
1.直接关闭iptables服务
2.配置iptables,开启10050端口 x.x.x.x:zabbix的IP地址
vi /etc/sysconfig/iptables #编辑防火墙配置文件
-A INPUT -s x.x.x.x -m state --state NEW -m tcp -p tcp --dport 10050:10051 -j ACCEPT
-A INPUT -s x.x.x.x -m state --state NEW -m udp -p udp --dport 10050:10051 -j ACCEPT
2.zabbix_get -s 127.0.0.1 -p 10050 -k system.uname 无数据 #Selinux原因
我直接关闭了Selinux.等有时间详细研究一下selinux配置
永久关闭方法：
vi /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
#修改为disabled
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
需重启机器
临时关闭方法：
[[email protected] selinux]# setenforce
usage: setenforce [ Enforcing | Permissive | 1 | 0 ] #0关闭 1开启
[[email protected] selinux]#
验证：
[[email protected] selinux]# getenforce
Disabled
