Zabbix监控,Mysql,Nginx,PHP-FTPM

一 Zabbix监控Mysql

监控Mysql,Zabbix提供了一个监控模板,所有可以直接使用.或者使用Percona提供的监控模板.

1. 使用自带监控模板

1.1.1 编写监控模板

#!/bin/bash

# 主机地址IP
MYSQL_HOST='127.0.0.1'

# 端口
MYSQL_PORT='3306'

# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -h${MYSQL_HOST} -P${MYSQL_PORT}"

# 检查参数是否正确
if [ $# -ne "1" ];then
    echo "arg Error!"
fi

# 获取数据
case $1 in
    Uptime)
        result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"`
        echo $result
        ;;
    Com_update)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3`
        echo $result
        ;;
    Slow_queries)
        result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"`
        echo $result
        ;;
    Com_select)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3`
        echo $result
                ;;
    Com_rollback)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3`
                echo $result
                ;;
    Questions)
        result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"`
                echo $result
                ;;
    Com_insert)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3`
                echo $result
                ;;
    Com_delete)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3`
                echo $result
                ;;
    Com_commit)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3`
                echo $result
                ;;
    Bytes_sent)
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3`
                echo $result
                ;;
    Bytes_received)
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3`
                echo $result
                ;;
    Com_begin)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3`
                echo $result
                ;; 

        *)
        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|C
om_begin)"
        ;;
esac

1.1.2 异常处理

　　如果mysql5.7以上版本执行脚本出现Waring信息,解决如下:

[mnysqladmin]
user=root
password=xxxxx

1.1.3 添加权限以及定义监控项

# 添加权限属主信息
chmod 755 check_mysql.sh
chown zabbix.zabbix check_mysql.sh
chmod +x check_mysql.sh

# /etc/zabbix/zabbix_agentd.d 下创建 UserParameter_mysql.conf文件,内容如下:
UserParameter=mysql.status[*],/etc/zabbix/zabbix_agentd.d/check_mysql.sh $1
UserParameter=mysql.ping,HOME=/etc /usr/local/mysql/bin/mysqladmin ping  2>/dev/null| grep -c alive
UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V

1.1.4 Mysql监控主机添加模板

二 监控Nginx

2.1.1 开启Nginx状态页

location /nginx-status {
  stub_status on;
  access_log  off;
  allow 127.0.0.1;
  deny all;
}

# 这段location是打开nginx的状态监控页面，
“stub_status”为“on”表示开启状态监控模块，
“access_log  off”表示关闭这个页面的访问日志，
接下来的“allow”表示这个状态监控页面允许哪些客户端访问，一般允许本机（127.0.0.1）除了允许访问的客户端外，其它都通过“deny all”禁止访问即可。

2.1.2 检查 & 参数说明

# curl http://127.0.0.1/nginx-status
Active connections: 3
server accepts handled requests
 1649812 1649812 2770589
Reading: 0 Writing: 1 Waiting: 2 

# 参数说明
Active connections: 对后端发起的活动连接数；
accepts：nginx总共处理了多少个连接；
handled：nginx成功创建了几次握手；
requests：nginx总共处理了多少请求。
Reading：nginx读取客户端的header数；
Writing: nginx 返回给客户端的header数；
Waiting: nginx 请求处理完成，正在等待下一请求指令的连接.

2.1.3 编写Nginx监控脚本

# cat nginx_status.sh
#!/bin/bash
# Set Variables
HOST=127.0.0.1
PORT="80"

if [ $# -eq "0" ];then
    echo "Usage:$0(active|reading|writing|waiting|accepts|handled|requests|ping)"
fi 

# Functions to return nginx stats
function active {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Active' | awk '{print $NF}'
  }
function reading {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Reading' | awk '{print $2}'
  }
function writing {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Writing' | awk '{print $4}'
  }
function waiting {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
  }
function accepts {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $1}'
  }
function handled {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $2}'
  }
function requests {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $3}'
  }
function ping {
    /sbin/pidof nginx | wc -l
}
# Run the requested function
$1

　　添加执行权限,以及编写UserParameter

chmod 755 nginx_status.sh
chmod +x nginx_status.sh
chown zabbix. nginx_status.sh 

# 在/etc/zabbix/zabbix_agentd.d 创建UserParameter_nginx.conf 内容如下:
UserParameter=nginx.status[*],/etc/zabbix/shell/nginx_status.sh  $1

2.1.4 创建模板以及链接主机
