zabbix监控nginx
a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）
在b机器（zabbix客户端）操作：
编辑nginx虚拟主机配置文件：
[root@centos ~]# vi /etc/nginx/conf.d/default.conf
在server{}中添加以下内容：
location /nginx_status
{
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}重载nginx配置：
[root@centos ~]# nginx -s reload
测试：
[root@centos ~]# curl http://127.0.0.1/nginx_status active connections: 1 server accepts handled requests 3 3 3 reading: 0 writing: 1 waiting: 0
#nginx状态信息已显示
状态说明：
添加监控脚本:
vi /usr/local/sbin/ngx_status.sh
添加以下内容：
#!/bin/bash
url="http://127.0.0.1/nginx_status"
curl=/usr/bin/curl
# 检测nginx进程是否存在
function ping {
/sbin/pidof nginx | wc -l
}
# 检测nginx性能
function active {
$curl $url 2>/dev/null| grep 'active' | awk '{print $nf}'
}
function reading {
$curl $url 2>/dev/null| grep 'reading' | awk '{print $2}'
}
function writing {
$curl $url 2>/dev/null| grep 'writing' | awk '{print $4}'
}
function waiting {
$curl $url 2>/dev/null| grep 'waiting' | awk '{print $6}'
}
function accepts {
$curl $url 2>/dev/null| awk nr==3 | awk '{print $1}'
}
function handled {
$curl $url 2>/dev/null| awk nr==3 | awk '{print $2}'
}
function requests {
$curl $url 2>/dev/null| awk nr==3 | awk '{print $3}'
}
$1添加权限：
[root@centos ~]# chmod 755 /usr/local/sbin/ngx_status.sh
编辑zabbix_agent配置文件：
[root@centos ~]# vi /etc/zabbix/zabbix_agentd.conf
在option：userparameter处添加：userparameter=nginx.status[*],/usr/local/sbin/ngx_status.sh $1
重启服务：
[root@centos ~]# systemctl restart zabbix-agent
在a机器（服务端）测试：
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -k 'nginx.status[accepts]' 6
在本机创建.xml文件并添加以下内容：（文件名称自定义）
<?xml version="1.0" encoding="utf-8"?>

</zabbix_export>在zabbix前端页面点击配置→模板→导入：
#导入刚才创建的xml文件即可
导入成功后在主机列表页面选择被监控的机器（b机器）链接该模板即可开始监控nginx
zabbix监控tomcat
a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）
在a机器安装zabbix-java-gateway：
[root@zabbix ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm [root@zabbix ~]# yum -y localinstall zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm
编辑gateway配置文件：
[root@zabbix ~]# vi /etc/zabbix/zabbix_java_gateway.conf
去掉listen_ip、listen_port(监听端口)、start_pollers(进程数)的注释符号#：
#listen_ip定义被监控机器的地址，不指定默认监听全部机器
编辑server配置文件：
[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf
定义以下3个配置参数：
启动zabbix-java-gateway服务：
[root@zabbix ~]# systemctl start zabbix-java-gateway
重启zabbix-server服务：
[root@zabbix ~]# systemctl restart zabbix-server
查看监听端口：
[root@zabbix ~]# netstat -lntp |grep java tcp6 0 0 :::10052 :::* listen 8706/java
开启jmx
在b机器编辑tomcat配置文件：
[root@centos ~]# vi /usr/local/tomcat/bin/catalina.sh
添加以下内容：
export catalina_opts="$catalina_opts -dcom.sun.management.jmxremote -djava.rmi.server.hostname=192.168.234.125 -dcom.sun.management.jmxremote.port=9999 -dcom.sun.management.jmxremote.ssl=false -dcom.sun.management.jmxremote.authenticate=false"
#hostname定义b机器地址，端口9999（默认12345）
重启tomcat：
[root@centos ~]# /usr/local/tomcat/bin/shutdown.sh [root@centos ~]# /usr/local/tomcat/bin/startup.sh
查看监听端口9999：
[root@centos ~]# netstat -lntp |grep 9999 tcp6 0 0 :::9999 :::* listen 25861/java
进入zabbix前端页面添加主机：
#与普通情况添加监控主机不同，监控b机器的tomcat需要配置jmx接口
模板链接jmx相关的两个模板：
当jmx图标变绿即表示配置成功：
zabbix监控mysql
a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）
zabbix_agent定义mysql监控的配置文件：/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
在b机器登录mysql创建用户：
mysql> grant usage,process,replication client on *.* to zamysql@'localhost' identified by 'zamysql';
创建配置文件指定的目录：
[root@centos ~]# mkdir /var/lib/zabbix
创建my.cnf文件：
[root@centos ~]# vi /var/lib/zabbix/.my.cnf
#需要注意该文件是隐藏文件
添加以下内容：
[mysql] host=localhost user=zamysql password='zamysql' socket=/tmp/mysql.sock [mysqladmin] host=localhost user=zamysql password='zamysql' socket=/tmp/mysql.sock
在a机器测试：
