一.使用zabbix监控nginx
博主推荐阅读: https://www.cnblogs.com/yinzhengjie2020/p/12340063.html
二.zabbix agent主机开启支持远程命令管理功能
1>.开启zabbix agent的允许运行远程命令功能
[root@nginx201.yinzhengjie.org.cn ~]# grep EnableRemoteCommands= /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf # EnableRemoteCommands=0 [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]# sed -r -i 's@# (EnableRemoteCommands=)0@11@' /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]# grep EnableRemoteCommands= /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf EnableRemoteCommands=1 [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]#
2>.开启zabbix agent的允许运行特殊字符功能
[root@nginx201.yinzhengjie.org.cn ~]# grep UnsafeUserParameters= /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf # UnsafeUserParameters=0 [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]# sed -r -i 's@# (UnsafeUserParameters=)0@11@' /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]# grep UnsafeUserParameters= /yinzhengjie/softwares/zabbix/etc/zabbix_agentd.conf UnsafeUserParameters=1 [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]#
3>.重启zabbix agent服务
[root@nginx201.yinzhengjie.org.cn ~]# systemctl restart zabbix-agent.service
4>.编辑sudoers文件，为zabbix用户提权
[root@nginx201.yinzhengjie.org.cn ~]# grep "^[a-Z]" /etc/sudoers Defaults !visiblepw Defaults always_set_home Defaults match_group_by_gid Defaults always_query_group_plugin Defaults env_reset Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE KDEDIR LS_COLORS" Defaults env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE" Defaults env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES" Defaults env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE" Defaults env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY" Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin root ALL=(ALL) ALL zabbix ALL=(ALL) NOPASSWD: ALL [root@nginx201.yinzhengjie.org.cn ~]# [root@nginx201.yinzhengjie.org.cn ~]#
三.zabbix webUI定义重启nginx的动作
1>.点击"创建动作"
2>.添加触发条件
3>.自定义启动Nginx的命令
4>.点击"添加"，完成动作的创建
5>.动作创建成功
6>.手动停止nginx
7>.查看web界面
8>.nginx启动成功
9>.nginx启动失败请检查上面的命令是否少加了sudo关键字
sudo /yinzhengjie/softwares/nginx/sbin/nginx
