一、环境说明
1、服务器角色
2、系统环境
CentOS 6.2 x86_64
3、环境要求
(1)、mysql/' target='_blank'>mysql 5.0 及以上 (用来存储监控系统采集的数据)
(2)、Apache 2.2 及以上 (WEB 服务器运行服务器)
(3)、PHP 5.3 以上 (WEB 界面)
(4)、python/' target='_blank'>python 2 (推荐 2.7 版本,其他版本未做测试,执行数据采集和报警任务)
(5)、MySQLdb for Python (Python 连接 MySQL 的接口)
二、Python基础环境部署
https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
# tar xvzf Python-2.7.6.tgz# cd Python-2.7.6# ./configure --prefix=/usr/local/python2.7 --enable-shared# make && make install# echo '/usr/local/python2.7/lib' >> /etc/ld.so.conf# /sbin/ldconfig# mv /usr/bin/python /usr/bin/python_old# ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
为避免 python 版本过高,导致 yum 不可以,需做如下修改:
# vim /usr/bin/yum
由 #!/usr/bin/python 修改为 #!/usr/bin/python_old
http://pypi.python.org/packages/source/d/distribute/distribute-0.6.28.tar.gz
# tar xvzf distribute-0.6.28.tar.gz# cd distribute-0.6.28# python setup.py installhttps://github.com/farcepest/MySQLdb1/archive/MySQLdb-1.2.5.tar.gz# tar xvzf MySQLdb1-MySQLdb-1.2.5.tar.gz# cd MySQLdb1-MySQLdb-1.2.5# vim site.cfgmysql_config =/usr/local/mysql/bin/mysql_config……# python setup.py build# python setup.py install
三、mysqlmtop环境部署
1、创建监控机数据库并授权
# mysql -uroot -e "create database mysqlmtop default character set utf8;"# mysql -uroot -e "grant all privileges on mysqlmtop.* to 'mtop_user'@'%' identified by '123456';"# mysql -uroot -e "flush privileges;"
2、导入SQL文件夹里的SQL文件(表结构和数据文件)
# unzip mysqlmtop_v2.1.zip# cd mysqlmtop_v2.1# mysql -uroot mysqlmtop < sql/mysqlmtop.sql# mysql -uroot mysqlmtop < sql/mysqlmtop_data.sql
3、在被监控机上创建授权账号
# mysql -uroot -e "grant select,super,process on *.* to 'monitor'@'172.18.35.29' identified by 'monitor';"# mysql -uroot -e "flush privileges;"
4、mysqlmtop配置
# cp -a mysqlmtop /usr/local/# cp -a frontweb /data/web/data/ # cd /usr/local/mysqlmtop/# vim etc/config.ini
# chmod +x *.py *.sh mtopctl# ln -s /usr/local/mysqlmtop/mtopctl /usr/local/bin
( 注意:需要使用dos2unix命令对*.py、*.sh、mtopctl文件进行格式转换,否则会运行失败 )
5、测试MySQL连接是否正常
# cd /usr/local/mysqlmtop && ./test_mysql.py
MySQLDB OK!
6、启动监控系统
# mtopctl start
7、前端WEB展示层配置
# cd /data/web/data/frontweb/# chown -R nobody:nogroup /data/web/data/frontweb# chmod -R 750 /data/web/data/frontweb# vim application/config/database.php
# vim /data/web/conf/mysqlmtop.conf<VirtualHost *:80> DocumentRoot /data/web/data/frontweb ServerName mysqlmtop.test.com DirectoryIndex index.php AddDefaultCharset UTF-8 <LocationMatch "/data/web/.*\.php$"> Order Deny,Allow Deny from All </LocationMatch> <Directory /> AllowOverride ALL </Directory></VirtualHost># service httpd graceful
然后本地hosts绑定(172.18.35.29 mysqlmtop.test.com)
通过 http://mysqlmtop.test.com 即可访问(初始授权账号:admin admin)
8、监控项设置
点击管理中心 --> 应用管理 添加应用
点击管理中心 --> 服务器管理 添加 MySQL 服务器
四、慢查询配置
1、在被监控服务器安装如下组件
http://cpan.metacpan.org/authors/id/T/TI/TIMB/DBI-1.628.tar.gz
# tar xvzsf DBI-1.628.tar.gz# cd DBI-1.628# perl Makefile.PL# make && make install
http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.024.tar.gz
# tar xvzf DBD-mysql-4.024.tar.gz# cd DBD-mysql-4.024# perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql# make && make install
http://search.cpan.org/CPAN/authors/id/S/SU/SULLR/IO-Socket-SSL-1.972.tar.gz
# tar xvzf IO-Socket-SSL-1.972.tar.gz# cd IO-Socket-SSL-1.972# perl Makefile.PL# make && make install
http://www.percona.com/redir/downloads/percona-toolkit/LATEST/percona-toolkit-2.2.7.tar.gz
# tar xvzf percona-toolkit-2.2.7.tar.gz# cd percona-toolkit-2.2.7# perl Makefile.PL# make && make install
2、开启 MySQL 本身的慢查询功能
slow_query_log = 1slow_query_log_file = /data/dbdata/slow_query.loglong_query_time = 1
3、在被监控服务器(10.160.22.14)上添加如下 crontab 项
00 * * * * /usr/bin/pt-query-digest --user=mtop_user --password=123456 --port=3306 --review h=172.18.35.29,D=mysqlmtop,t=mysql_slow_query_review_4 --history h=172.18.35.29,D=mysqlmtop,t=mysql_slow_query_review_history_4 --no-report --limit=0% /data/dbdata/slow_query.log >/dev/null 2>&1
4、在被监控服务器(10.160.22.47)上添加如下 crontab 项
00 * * * * /usr/bin/pt-query-digest --user=mtop_user --password=123456 --port=3306 --review h=172.18.35.29,D=mysqlmtop,t=mysql_slow_query_review_5 --history h=172.18.35.29,D=mysqlmtop,t=mysql_slow_query_review_history_5 --no-report --limit=0% /data/dbdata/slow_query.log >/dev/null 2>&1
以上数据表 mysql_slow_query_review、mysql_slow_query_review_history 的后缀为主机 ID,如图:

三、工具组件配置
1、在被监控服务器(172.18.35.29)上添加如下 crontab 项
*/30 * * * * cd /usr/local/mysqlmtop; ./check_mysql_widget_bigtable.py >/dev/null 2>&1*/1 * * * * cd /usr/local/mysqlmtop; ./check_mysql_widget_hit_rate.py >/dev/null 2>&1*/1 * * * * cd /usr/local/mysqlmtop; ./check_mysql_widget_connect.py >/dev/null 2>&1
2、效果展示
四、资源监控配置
1、被监控服务器上的设置
NET-SNMP服务安装(注意版本):
ftp://ftp.fi.freebsd.org/pub/FreeBSD/ports/distfiles/net-snmp-5.3.2.tar.gz
# tar xvzf net-snmp-5.3.2.tar.gz# cd net-snmp-5.3.2# ./configure --prefix=/usr/local/snmp \--enable-mfd-rewrites \--with-default-snmp-version="2" \--with-sys-contact="lovezym5@qq.com" \--with-sys-location="China" \--with-logfile="/var/log/snmpd.log" \--with-persistent-directory="/var/net-snmp"# make && make install# cp EXAMPLE.conf /usr/local/snmp/share/snmp/snmpd.conf# vim /usr/local/snmp/share/snmp/snmpd.confcom2sec notConfigUser 172.18.35.29 mysqlmtopgroup notConfigGroup v1 notConfigUsergroup notConfigGroup v2c notConfigUsergroup notConfigGroup usm notConfigUserview all included .1 80access notConfigGroup "" any noauth exact all none none......
服务启动:
# /usr/local/snmp/sbin/snmpd -c /usr/local/snmp/share/snmp/snmpd.conf
2、监控服务器上的设置
NET-SNMP服务安装:
# tar xvzf net-snmp-5.3.2.tar.gz# cd net-snmp-5.3.2# ./configure --prefix=/usr/local/snmp \--enable-mfd-rewrites \--with-default-snmp-version="2" \--with-sys-contact="lovezym5@qq.com" \--with-sys-location="China" \--with-logfile="/var/log/snmpd.log" \--with-persistent-directory="/var/net-snmp"# make && make install# cd /usr/local/mysqlmtop# ln -s /usr/local/snmp/bin/snmpwalk /usr/bin/snmpwalk# ln -s /usr/local/snmp/bin/snmpdf /usr/bin/snmpdf# vim /usr/local/mysqlmtop/check_linux_resource.shhost="172.18.35.29"port="3306"user="mtop_user"password="123456"dbname="mysqlmtop"......# vim /usr/local/mysqlmtop/etc/config.ini[linux_server]server_ip="10.160.22.14|10.160.22.47"
重启监控服务:
# mtopctl stop && mtopctl start
问题修正(否则无法获取内存信息):
# vim /usr/local/mysqlmtop/check_linux_resource.shtotalmem=`/usr/bin/snmpdf -v1 -c mysqlmtop ${ip} | awk '/Real Memory/ {print $3}'`usedmem=`/usr/bin/snmpdf -v1 -c mysqlmtop ${ip} | awk '/Real Memory/ {print $4}'`
crontab 内容添加:
*/1 * * * * cd /usr/local/mysqlmtop; ./check_linux_resource.py >/dev/null 2>&1
效果展示
