Chapter 1 Introduction lepus
Lepus is a set of open-source database monitoring platform, now supports basic monitoring and alerting MySQL, Oracle, SQLServer, MongoDB, Redis and other databases (MySQL already supports replication monitoring, slow query analysis and advanced features such as directional push). After Lepus need to deploy scripts or Agent on each database server, only you need to create an account in the authorization database, you can remotely monitor, monitor database servers for more companies and monitoring the cloud database, which will monitor the company greatly simplified deployment processes while Lepus system built a wealth of performance monitoring indicators, enables companies to identify potential performance problems before database processing downtime, reduce the direct loss of business because of problems caused by database.
Essential requirements of Chapter 2 Software Installation
Software needs LAMP environment, you need a core package as follows:
The following packages need only be deployed to monitor the machine. Monitored machine without having to deploy.
1.MySQL5.1 and above (to be used to store data collected by the monitoring system)
2.Apache 2.2 and above (must, WEB server running server)
3.PHP 5.3 above (must provide support WEB interface does not support PHP7)
4.Python2 (must recommend version 2.6 and above, perform data acquisition and alarm tasks, does not support Python3)
5.Python monitoring database connections and associated drive module package:
MySQLdb for python (Python MySQl connection interface for monitoring MySQL, this module must be installed)
cx_oracle for python (Python Oracle connection interface, not necessarily, you need to be monitored if this oracle modules must be installed)
Pymongo for python (Python interface MongoDB, the non-essential, if desired MongoDB monitoring module must be installed)
redis-py for python (Python Redis connection interface, not necessarily, if necessary Redis monitoring module must be installed)
The installation demonstrates the use of the following packages to build:

Chapter 3 Software Installation
3.1 build LAMP environment
This is used to build a manual way to accomplish LAMP environment
3.1.1 compile and install httpd service
Unzip directory and create an account for http www service
[root@m02 ~]# cd /tools [root@m02 tools]# tar xf httpd-2.2.31 [root@m02 tools]# cd httpd-2.2.31 [root@m02 tools]# useradd www -s /sbin/nologin -M
Install the necessary software package zlib
[root@m02 httpd-2.2.31]# yum install zlib zlib-devel -y
Installation and execution profile
[root@m02 httpd-2.2.31]# ./configure --prefix=/application/apache2.2.31 --enable-deflate --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-rewrite [root@m02 httpd-2.2.31]# make && make install
Create a soft link and start the service
[root@m02 httpd-2.2.31]# ln -s /application/apache2.2.31/ /application/apache [root@m02 httpd-2.2.31]# /application/apache/bin/apachectl start [root@m02 httpd-2.2.31]# netstat -lntup|grep http tcp 0 0 :::80 :::* LISTEN 57310/httpd
3.1.2 based on the configuration of the virtual hosts apache
Virtual host configuration aim is to detect whether the service can display the home page http normal.
To www.test.com example to configure a home page
[root@m02 apache]# cd /application/apache/htdocs/ [root@m02 apache]# mkdir www
Modify the page configuration file httpd.conf
[root@m02 htdocs]# vim /application/apache/conf/httpd.conf
Search / httpd-v, the foregoing comments removed.
# Virtual hosts Include conf/extra/httpd-vhosts.conf
Search the file Servername comment open, if there is a need to modify the network IP address.
ServerName 127.0.0.1:80
Edit the configuration file httpd-vhosts.conf page http
[root @ M02 htdocs] # vim /application/apache/conf/extra/httpd-vhosts.conf
<VirtualHost *: 80>
ServerAdmin [email protected] # administrator mailbox
DocumentRoot "/application/apache2.2.31/htdocs/www " # page virtual directory
ServerName www.test.com # domain
ServerAlias test.com # alias
ErrorLog" logs / www_error_log " # error log
CustomLog" logs / www_access_log "the Common # access log
</ VirtualHost>
Establish a home page file used to test whether normal
[root@m02 htdocs]# echo 'Apache www' >www/index.html
Restart the server to refresh the configuration
[root@m02 apache]# /application/apache/bin/apachectl -t [root@m02 apache]# /application/apache/bin/apachectl graceful
Modify the client's hosts file to add the IP address of our page, if the content apache www www.test.com access through a browser appears, it shows the apache successfully completed structures.
3.1.3 install mysql
This is done directly by way of a single instance of the installation.
[root@m02 apache]# cd /tools [root@m02 tools]# useradd -s /sbin/nologin -M mysql [root@m02 tools]# tar xf mysql-5.5.49-linux2.6-x86_64.tar.gz [root@m02 tools]# mv mysql-5.5.49-linux2.6-x86_64 /application/mysql-5.5.49 [root@m02 tools]# ln -s /application/mysql-5.5.49/ /application/mysql [root@m02 tools]# chown -R mysql:mysql /application/mysql [root@m02 tools]# cd /application/mysql [root@m02 mysql]# ./scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql
3.1.4 mysql debugging and open database
[root@m02 mysql]# cd bin/ [root@m02 bin]# sed -i 's#/usr/local/#/application/#g' mysqld_safe [root@m02 bin]# cd ../ [root@m02 mysql]# \cp support-files/my-small.cnf /etc/my.cnf [root@m02 mysql]# echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile [root@m02 mysql]# . /etc/profile [root@m02 mysql]# sed -i 's#/usr/local/#/application/#g' support-files/mysql.server [root@m02 mysql]# cp support-files/mysql.server /etc/init.d/mysqld [root@m02 mysql]# chmod +x /etc/init.d/mysqld [root@m02 mysql]# chkconfig --add mysqld [root@m02 mysql]# /etc/init.d/mysqld start
3.1.5 php5.5.32 installation
cd /tools/ [root@m02 tools]# tar xf libiconv-1.14.tar.gz [root@m02 tools]# cd libiconv-1.14 [root@m02 libiconv-1.14]# ./configure --prefix=/usr/local/libiconv [root@m02 libiconv-1.14]# make && make install [root@m02 libiconv-1.14]# cd ../ [root@m02 tools]# yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel mhash mcrypt openssl-devel pcre-devel -y [root@m02 tools]# tar xf php-5.5.32.tar.gz [root@m02 tools]# cd php-5.5.32 [root@m02 php-5.5.32]# ./configure --prefix=/application/php5.5.32 --with-mysql=/application/mysql --with-pdo-mysql=/application/mysql --with-iconv-dir=/usr/local/libiconv --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-soap --enable-short-tags --enable-static --with-xsl --with-fpm-user=www --with-fpm-group=www --enable-opcache=no --with-apxs2=/application/apache/bin/apxs --enable-ftp [root@m02 php-5.5.32]# ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/ [root@m02 php-5.5.32]# touch ext/phar/phar.phar [root@m02 php-5.5.32]# make [root@m02 php-5.5.32]# make install [root@m02 php-5.5.32]# ln -s /application/php5.5.32 /application/php [root@m02 php-5.5.32]# cp php.ini-production /application/php/lib/php.ini [root@m02 php-5.5.32]# cd /application/php/etc [root@m02 etc]# cp php-fpm.conf.default php-fpm.conf [root@m02 etc]# grep libphp5.so /application/apache/conf/httpd.conf [root@m02 etc]# ls /application/apache/modules/ [root@m02 etc]# /application/php/sbin/php-fpm

cd /tools/lepus_v3.7 cp -rf php/* /application/apache/htdocs/www/
Lepus modify the database connection file
vim /application/apache/htdocs/www/application/config/database.php
$db['default']['hostname'] = '127.0.0.1'; $db['default']['port'] = '3306'; $db['default']['username'] = 'lepus_user'; $db['default']['password'] = '123456'; $db['default']['database'] = 'lepus'; $db['default']['dbdriver'] = 'mysql';
To modify the ServerName native 127.0.0.1:80
Modify the virtual configuration file
/application/apache/conf/extra/httpd-vhosts.conf
Restart apache service and modify the configuration file
/usr/local/lepus/etc/config.ini Vim ### monitoring machine MySQL database connection address ### [monitor_server] Host = "127.0.0.1" Port = 3306 User = "lepus_user" the passwd = "123456" dbname = "lepus"
Start lepus Service
cd /usr/local/lepus/ lepus start ps -ef|grep lepus
But because it has not added a host, so view the log will see the following prompt is a normal prompt. Of course, this step can also be started after the completion of the deployment Lepus WEB console.
Admin login page User name Password Lepusadmin.
Chapter 4 Adding MySQL monitoring instance
Lepus is the use of remote monitoring database connections into data acquisition, so no need to deploy the relevant agent or scheduled tasks on the database server. But it needs to be granted access to the database side, and then configure instances WEB end it. As shown in the following steps.
First, we performed the authorization being monitored database, allowing the use Lepus collector can connect to the database server, perform the following command to authorize the monitored database.
On the database server to be monitored authorization, we are now multi-instance database on borrowed 10.0.0.52 3306 to operate the test
grant select,process,super on *.* to 'lepus_user'@'10.0.0.%' identified by '123456'; flush privileges;
Once created, you can configure the host entry in the page.
