安装配置MySQLMTOP来监控MySQL运行性能的教程
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 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 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 install https://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.cfg mysql_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 = 1 slow_query_log_file = /data/dbdata/slow_query.log long_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:
5、为被监控的服务器开启慢查询

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

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.conf com2sec notConfigUser 172.18.35.29 mysqlmtop group notConfigGroup v1 notConfigUser group notConfigGroup v2c notConfigUser group notConfigGroup usm notConfigUser view all included .1 80 access 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.sh host="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.sh totalmem=`/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
