Linux云计算架构-Zabbix4-4-6监控apache和mysql
1. 环境介绍
zabbix4-4-6基于LAMP环境部署。
服务器IP：192.168.8.173
客户端IP：192.168.8.172
服务端可以正常监控服务端本身和远程客户端。
2. 监控客户端apache
2.1 安装apache，并测试获取apache状态
# 配置apache
# yum安装apache
[root@client ~]# yum install -y httpd
# 修改httpd配置文件,在末尾添加本地服务器状态页面
[root@client ~]# vim /etc/httpd/conf/httpd.conf
ExtendedStatus On
<location /server-status>
SetHandler server-status
Order allow,deny
Allow from 127.0.0.1 192.168.8.0/24
</location>
95 ServerName localhost:80
# 重启httpd服务，并放行80端口号
[root@client ~]# systemctl restart httpd.service
[root@client ~]# netstat -antup | grep httpd
tcp6 0 0 :::80 :::* LISTEN 9624/httpd
[root@client ~]# firewall-cmd --permanent --zone=public --add-port=80/tcp
success
[root@client ~]# firewall-cmd --reload
success
查看网址：http://192.168.8.172/server-status是否显示正常，该页面用于收集客户端上apache服务的信息。
2.2 客户端添加apache模板
为客户端添加apache模板
2.3 查看apache监控数据

2.4 对apache进行压力测试
# 压测测试一下
[root@client ~]# ab -n 1000 -c 1000 http://192.168.8.172/

3. 监控客户端mysql
3.1 安装mysql数据库并设置zabbix用户
# 安装mysql数据库
[root@client ~]# yum install mariadb-server -y
# 启动并设置开机自启
[root@client ~]# systemctl start mariadb.service
[root@client ~]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
# 登录数据库，创建zabbix用户，并授权usage
[root@client ~]# mysql -uroot
Welcome to the MariaDB monitor. Commands end with ; or \g.

Bye
# 测试下zabbix用户是否可以登录数据库
[root@client ~]# mysql -uzabbix -p123456

MariaDB [(none)]> exit

3.2 添加mysql监控模板文件并配置zabbix用户免密登录
# 复制一份mysql监控模板文件
[root@client ~]# cp /usr/share/doc/zabbix-agent-4.4.6/userparameter_mysql.conf /etc/zabbix/zabbix_agentd.d/
# 查看客户端配置文件
[root@client ~]# vim /etc/zabbix/zabbix_agentd.conf
290 Include=/etc/zabbix/zabbix_agentd.d/*.conf
# 设置zabbix用户免密登录
[root@client ~]# vim /etc/my.cnf.d/client.cnf
[client]
user=zabbix
password=123456
# 测试zabbix免密登录
[root@client ~]# mysql

1 row in set (0.00 sec)
# 重启zabbix客户端
[root@client ~]# systemctl restart zabbix-agent
[root@client ~]# systemctl enable zabbix-agent
3.3 添加zabbix的mysql监控模板
3.4 查看mysql数据
点了应用之后，数据可能出来的比较慢
查看堆叠数据图
有很多项都没数据，因为没有客户端连接数据库。
3.5 压测mysql数据库
# mysqlslap是mysql数据库自带的压测工具，可模拟出大量客户端对数据库同时进行操作，通过监控数据库来了解数据库的性能。
[root@client ~]# mysqlslap -uroot -p --concurrency=100 --number-of-queries=1000 --number-int-cols=5 --number-char-cols=20 --auto-generate-sql
Enter password: # 没有密码，直接回车
Benchmark
Average number of seconds to run all queries: 1.148 seconds # 运行所有语句的平均秒数
Minimum number of seconds to run all queries: 1.148 seconds # 运行所有语句的最小描述
Maximum number of seconds to run all queries: 1.148 seconds # 运行所有语句的最大秒数
Number of clients running queries: 100 # 客户端数量
Average number of queries per client: 10 # 每个客户端运行查询的平均数
--concurrency # 当前客户端连接数
--number-of-queries # 总的测试查询次数
--number-int-cols # 生成5个int类型的列
--number-char-cols # 生成20个char类型的列
--auto-generate-sql # 自动生成sql脚本
可以看到已经有数据产生了。
以上就是使用zabbix监控apache和mysql数据库的全过程了。说实话，zabbix4-4-6版本会比zabbix3-4-3版本配置监控apache和mysql容易一些，但也有很多类似的地方。即是zabbix4-4-6有很多地方都优化了，也更方便了。
