Zabbix监控Nginx

主机环境:

Zabbix版本:3.4.9
nginx版本:1.14.0
主机防火墙和selinux关闭
Zabbix yum安装参考:https://www.tracymc.cn/archives/614,编译安装可参考https://www.tracymc.cn/archives/218.
nginx安装参考:https://www.tracymc.cn/archives/431
nginx模板地址:https://github.com/adubkov/zbx_nginx_template
前提条件:
主机安装了python(因为脚本是python写的)、nginx编译参数包含http_stub_status_module并且开启了access.log
查看nginx编译参数:
[root@test zabbix]# nginx -V
nginx version: nginx/1.14.0
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)

具体步骤:
1.下载脚本并配置相关参数
[root@test home]# wget https://github.com/adubkov/zbx_nginx_template/archive/master.zip
[root@test home]# unzip master.zip
[root@test home]# cd zbx_nginx_template-master/
[root@test zbx_nginx_template-master]# ll
总用量 56
-rwxr-xr-x 1 root root 1979 12月 16 11:28 README.md
-rwxr-xr-x 1 root root 5614 12月 16 11:28 zbx_nginx_stats.py
-rwxr-xr-x 1 root root 42775 12月 16 11:28 zbx_nginx_templates.xml
将zbx_nginx_stats.py复制到zabbix脚本执行目录,如下:
[root@test zbx_nginx_template-master]# cp zbx_nginx_stats.py /etc/zabbix/scripts/ //根据自己情况定义脚本路径
修改zbx_nginx_stats.py内容：
zabbix_host = '127.0.0.1' # Zabbix server IP
zabbix_port = 10051 # Zabbix server port
hostname = 'Zabbix server' # Name of monitored host, like it shows in zabbix web ui,这里的名字一定要和web页面配置的名字一样!!!!!!不然可能会没有数据.如果web配置的名字和主机名不一样的话,以web名字为准!!!!!!
time_delta = 1 # grep interval in minutes

# URL to nginx stat (http_stub_status_module)
stat_url = 'http://127.0.0.1:8080/nginx_stat'

# Nginx log file path
nginx_log_file_path = '/var/log/nginx/access.log'

# Optional Basic Auth
username = 'user'
password = 'pass'

# Temp file, with log file cursor position
seek_file = '/tmp/nginx_log_stat'

[root@test scripts]# chmod u+x zbx_nginx_stats.py //赋予执行权限

2.修改nginx配置
nginx配置文件增加如下配置(在server段):
location /nginx_stat {
stub_status on; # Turn on nginx stats
access_log off; # We do not need logs for stats
allow 127.0.0.1; # Security: Only allow access from IP
allow ::1; # Security IPv6: allow only from localhost
deny all; # Deny requests from the other of the world
}
截图如下:
[root@test conf.d]# nginx -t //验证配置文件是否正确
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@test conf.d]# systemctl restart nginx //重启下
主机浏览器打开http://127.0.0.1:8080/nginx_stat验证nginx配置修改是否生效,如下:
