## 一、配置zabbix监控httpd服务 ##

在server2上：  
步骤一：安装apache并开启服务

yum install -y httpd
    systemctl start httpd
    systemctl enable httpd

步骤二：在zabbix-web界面设置  
配置 —>主机 —> server2 —> 模板 —>选择 —> Template App HTTP Service—> 添加 —>更新

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 1]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 2]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 3]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 4]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 5]  
可以看到server2主机的触发器多了一个httpd服务的触发器，是端口的触发器，zabbix是通过端口来检测httpd服务的。

步骤三：测试，模拟apache故障

systemctl stop httpd

![在这里插入图片描述][20200319212707766.png]  
步骤四：在web界面查看  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 6]

## 二、配置Zabbix监控nginx ##

步骤一：在监控主机server3上源码安装nginx服务，关闭 debug

yum install gcc pcre-devel zlib-devel -y
    tar zxf nginx-1.17.8.tar.gz 
    cd nginx-1.17.8
    vim auto/cc/gcc
      # debug
      #CFLAGS="$CFLAGS -g"
    ./configure --prefix=/usr/local/nginx --with-http_stub_status_module
    make && make install

![在这里插入图片描述][20200319221652828.png]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 7]  
![在这里插入图片描述][20200319221631960.png]

步骤二：修改nginx配置文件，添加监控模块

vim /usr/local/nginx/conf/nginx.conf
    
     47         location /status {
        
     48                 stub_status on;  #开启该模块
     49                 access_log off; #关闭日志记录
     50                 allow 127.0.0.1; #白名单 只允许本机访问
     51                 deny all;  
     52         }

![在这里插入图片描述][20200319221802405.png]  
![在这里插入图片描述][20200319221800122.png]  
步骤三：设置软链接并开启nginx服务

ln -s /usr/local/nginx/sbin/nginx /usr/sbin/
    nginx -t
    nginx

![在这里插入图片描述][20200319221833385.png]  
步骤四：在server3本机测试nginx服务是否部署成功

<table> 
 <thead> 
  <tr> 
   <th>Active connections</th> 
   <th>活跃的连接数</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>accepts</td> 
   <td>接收到的请求数（不一定回复）</td> 
  </tr> 
  <tr> 
   <td>handled</td> 
   <td>确定建立三次握手的请求数</td> 
  </tr> 
  <tr> 
   <td>requests</td> 
   <td>处理的请求数</td> 
  </tr> 
 </tbody> 
</table>

curl 127.0.0.1/status

![在这里插入图片描述][20200319221852247.png]  
抓取处理的活跃的连接数

curl -s http://localhost/status | grep Active | awk '{print $3}'

![在这里插入图片描述][2020031922191294.png]  
步骤五：修改server3的配置文件/etc/zabbix/zabbix\_agentd.d/userparameter\_nginx.conf，创建nginx的监控项

cd /etc/zabbix/zabbix_agentd.d/
    cp userparameter_mysql.conf userparameter_nginx.conf
    vim userparameter_nginx.conf 
    	UserParameter=nginx.active,curl -s http://localhost/status | grep Active | awk '{print $3}'
    systemctl restart zabbix-agent

![在这里插入图片描述][2020031922200470.png]  
步骤六：在web界面给server3添加nginx监控  
给 server3 配置监控项  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 9]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 10]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 11]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 12]  
这里要注意：键值一栏,填的内容需要和配置文件中 UserParameter 定义的 key 值相同，否则无效

新建图形并添加监控项：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 13]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 14]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 15]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 16]  
能看到有图形，但是发现汉字无法显示，是字体原因，配置字体  
在server1上：

cd /usr/share/zabbix/fonts #字体存放路径
    mv /root/simkai.ttf .    #网上下载字体simkai.ttf
    vim /usr/share/zabbix/include/defines.inc.php  #修改配置使新字体生效
     ## 搜索 FONT 关键字,发现使用的是 graphfont.ttf 字体
    :%s/graphfont/simkai/g   #替换为 simkai

![在这里插入图片描述][20200319222618597.png]查看已经替换了：  
![在这里插入图片描述][20200319222623379.png]  
刷新web页面，字体正常
