### 添加监控项 ###

zabbix监控是以：  
server->agent->host  
的顺序来获取受管主机信息的

以添加mysql监控为例

*  先建立mysql账户

grant select on *.* to zabbix@localhost identified by 'westos';

*  修改配置文件  
    查看/etc/zabbix/zabbix\_agentd.d/userparameter\_mysql.conf  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzQxNDAyNQ_size_16_color_FFFFFF_t_70_pic_cener]  
    在/var/lib/zabbix/下建立一个名为 .my.cnf的文件

[mysql]
    user=zabbix
    password=westos
    socket=/var/lib/mysql/mysql.sock
    
    [mysqladmin]
    user=zabbix
    password=westos
    socket=/var/lib/mysql/mysql.sock

*  在server端做测试

 *  在web管理界面添加模板

    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzQxNDAyNQ_size_16_color_FFFFFF_t_70_pic_ceter 1]

### 使用percona添加模板 ###

[官方文档][Link 1]

*  下载：

rpm -ivh https://www.percona.com/downloads/percona-monitoring-plugins/1.1.6/percona-zabbix-templates-1.1.6-1.noarch.rpm

在agent上安装php和php-mysql

*  复制配置文件

[root@server3 pkgs]# cd /var/lib/zabbix/percona/templates/
    [root@server3 templates]# ls
    userparameter_percona_mysql.conf  zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml
    [root@server3 templates]# cp userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/

查看/var/lib/zabbix/percona/scripts下的脚本文件  
![在这里插入图片描述][20200825214902208.png_pic_cnter]  
可以看出大概逻辑是 ：  
通过php脚本文件 查询mysql数据库的信息 -> 把查询到的信息放在/tmp下的一个文件中 -> 在通过shell来分析 取得需要的信息

*  在scripts下新建一个ss\_get\_mysql\_stats.php.cnf

<?php
    $mysql_user = 'root';
    $mysql_pass = 'westos';

![在这里插入图片描述][20200825220354816.png_pic_cnter]  
运行一下如果有输出说明 没问题

*  添加xml

### 自定义监控项 ###

以监控nginx状态为例，

*  1 在/etc/zabbix/zabbix\_agentd.d写自定义脚本

[root@server2 zabbix_agentd.d]# cat userparameter_nginx.conf 
     UserParameter=nginx.active,curl -s http://127.0.0.1/status | grep  Active | awk '{print$3}'

重启agent服务

*  2 在server端测试

[root@server1 ~]# zabbix_get -s 172.25.254.102 -p 10050 -k "nginx.active"
    1

*  3 添加监控项

### 监控java应用 ###

以监控tomcat为例：

*  1 在server2上安装tomcat并修改/usr/local/tomcat/bin/catalina.sh

100 # OS specific support.  $var _must_ be set to either true or false.
    101 CATALINA_OPTS='-Dcom.sun.management.jmxremote.port=8888
    102   -Dcom.sun.management.jmxremote.ssl=false
    103   -Dcom.sun.management.jmxremote.authenticate=false'

安装jdk并启动tomcat  
![在这里插入图片描述][20200826103510653.png_pic_cnter]

*  在server端安装zabbix-java-gateway.x86\_64  
    修改/etc/zabbix下zabbix\_server.conf

288 JavaGateway=172.25.254.101
    289 
    290 ### Option: JavaGatewayPort
    291 #       Port that Zabbix Java gateway listens on.
    292 #
    293 # Mandatory: no
    294 # Range: 1024-32767
    295 # Default:
    296 JavaGatewayPort=10052
    297 
    298 ### Option: StartJavaPollers
    299 #       Number of pre-forked instances of Java pollers.
    300 #
    301 # Mandatory: no
    302 # Range: 0-1000
    303 # Default:
    304 StartJavaPollers=5

启动zabbix-java-gateway.service  
重启zabbix-server.service

*  在web管理界面添加监控项

### 使用第三方平台处理报警信息 ###

*  1 注册  
    [睿象云][Link 2]
 *  2 在zabbix-server 上安装探针  
    1、切换到zabbix脚本目录  
    vi /etc/zabbix/zabbix\_server.conf  
    查看AlertScriptsPath  
    cd /usr/local/zabbix-server/share/zabbix/alertscripts  
    2、获取Cloud Alert Agent包：  
    wget https://download.aiops.com/ca\_agent/zabbix/ca\_zabbix\_release-2.1.0.tar.gz  
    3、解压、安装。  
    tar -xzf ca\_zabbix\_release-2.1.0.tar.gz  
    cd cloudalert/bin  
    ./install.sh 79be9d89-3d7b-44ef-889a-9b6807da4d1a
