zabbix监控nginx状态

在客户端部署zabbix agent

[root@node1 bag]# wget https://cdn.zabbix.com/zabbix/sources/stable/5.4/zabbix-5.4.4.tar.gz

[root@node1 bag]# ls
zabbix-5.4.4.tar.gz


#解压
[root@node1 bag]# tar xf zabbix-5.4.4.tar.gz -C  /usr/local/

安装依赖包和编译器

[root@node1 ~]#  yum -y install vim  wget gcc gcc-c++ make pcre-devel

创建用户

[root@node1 ~]#  useradd -r -M -s /sbin/nologin zabbix
[root@node1 ~]# id zabbix
uid=989(zabbix) gid=986(zabbix) groups=986(zabbix)

进入包编译安装

[root@node1 zabbix-5.4.4]# cd  /usr/local/zabbix-5.4.4/
[root@node1 zabbix-5.4.4]#  ./configure --enable-agent

修改配置文件

[root@node1 zabbix-5.4.4]# cd /usr/local/etc/
[root@node1 etc]# vim  zabbix_agentd.conf


Server=192.168.244.144  #server1 IP

Hostname=tom   #名字随便改

配置service文件可开机自启

[root@node1 etc]# vim  zabbix_agentd.conf

开启status：

location /status {
  stub_status {on | off};
  allow 172.16.0.0/16;
  deny all;
}

访问状态页面的方式：http://server_ip/status

状态页面信息详解：

在nginx.conf

        location /status {
            stub_status off;
            allow 192.168.244.144;
            allow 192.168.244.0/24;
            deny all;
        }

[root@node1 ~]# nginx -s reload
