Zabbix Server 和 Zabbix Agent 的详细安装过程（附带监控主机和监控参数的详细设置）
3、Zabbix Agent 安装 Nginx，并修改配置文件，并启动 Nginx
[root@Tang-1 ~]# yum install nginx -y
[root@Tang-1 ~]# vim /etc/nginx/nginx.conf
http {
server ｛
listen 80;
server_name localhost;
location /ngxstatus {
stub_status;
}
｝
｝
[root@Tang-1 ~]# systemctl start nginx.service
[root@Tang-1 ~]# systemctl status nginx.service

4、Zabbix Agent conf 文件修改，和脚本编写
4.1 /etc/zabbix/zabbix_agentd.conf 自定义参数
[root@Tang-1 ~]# vim /etc/zabbix/zabbix_agentd.conf
### Option: UserParameter
# User-defined parameter to monitor. There can be several user-defined parameters.
# Format: UserParameter=<key>,<shell command>
# See 'zabbix_agentd' directory for examples.
#
# Mandatory: no
# Default:
# UserParameter=
UserParameter=nginx.status[*],/usr/bin/ngxstatus.sh $1
4.2 /etc/zabbix/zabbix_agentd.conf 指定的脚本内容
[root@Tang-1 ~]# cat /usr/bin/ngxstatus.sh
#!/bin/bash
#
host='127.0.0.1'
port='80'
statusurl='/ngxstatus'
active() {
curl -s http://${host}:${port}${statusurl}|awk '/^Active/{print $3}'
}
accepts() {

curl -s http://${host}:${port}${statusurl}|awk 'NR==4{print $4}'
}
waiting() {
curl -s http://${host}:${port}${statusurl}|awk 'NR==4{print $6}'
}
$1
4.3 /etc/zabbix/zabbix_agentd.conf 指定的脚本测试，本机可访问成功

4.4 Zabbix Agent 重启程序，使 conf 文件生效
[root@Tang-1 ~]# systemctl restart zabbix-agent.service
[root@Tang-1 ~]# systemctl status zabbix-agent.service

5、Zabbix Server 运用 Get 命令，能成功进行参数获取
### 注意，参数格式要与 Zabbix Agent conf 文件中保持一致 ###
[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[waiting]"
0
[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[reading]"
0
[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[active]"
1
[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[handled]"

[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[requests]"

[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[writing]"
1
[root@Tang-2 ~]# zabbix_get -s 172.16.141.209 -p 10050 -k "nginx.status[accepts]"
96295
### 注意，参数格式要与 Zabbix Agent conf 文件中保持一致 ###
6、Zabbix Server Web GUI 配置
6.1 在 Hosts Tang-1 上进行 Item 添加
6.2 在 Hosts Tang-1 添加 Item 完毕（状态为 Enabled 为正常，如果是别的状态可能是 Item 状态不可用，进行 Item 检查）
6.3 进行图表查看，通过图表进行监控
