CentOS 7.2安装lepus数据库监控系统

Posted 2020-12-04 ssgeek

 

环境说明

系统版本 CentOS 7.2 x86_64

软件版本 lepus 3.7

Lepus是一套开源的数据库监控平台，目前已经支持mysql、Oracle、SQLServer、MongoDB、Redis等数据库的基本监控和告警（MySQL已经支持复制监控、慢查询分析和定向推送等高级功能）。Lepus无需在每台数据库服务器部署脚本或Agent，只需要在数据库创建授权帐号后，即可进行远程监控，适合监控数据库服务器较多的公司和监控云中数据库，这将为企业大大减化监控部署流程，同时Lepus系统内置了丰富的性能监控指标，让企业能够在数据库宕机前发现潜在性能问题进行处理，减少企业因为数据库问题导致的直接损失。

[[email protected] tools]# vim /root/.bash_profile

ORACLE_HOME="/usr/lib/oracle/11.2/client64"

PATH=$PATH:$ORACLE_HOME/bin

export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:/usr/local/lib

export LD_LIBRARY_PATH

[[email protected] tools]# source ~/.bash_profile        #修改完成后重新加载bash_profile文件

[[email protected] tools]# vim /etc/ld.so.conf

/usr/lib/oracle/11.2/client64/lib

[[email protected] tools]# ldconfig        #执行ldconfig生效

安装cx_oracle

[[email protected] tools]# tar xf cx_Oracle-5.2.1.tar.gz

[[email protected] tools]# cd cx_Oracle-5.2.1/

[[email protected] cx_Oracle-5.2.1]# python setup.py build

[[email protected] cx_Oracle-5.2.1]# python setup.py install

2.3 安装Pymongo for python（如果需要监控Mongodb则必须安装）

[[email protected] tools]# tar xf pymongo-2.7.tar.gz

[[email protected] tools]# cd pymongo-2.7/

[[email protected] pymongo-2.7]# python setup.py install

2.4 安装Redis 驱动 （如果需要监控Redis则必须安装）

[[email protected] tools]# tar xf redis-py-2.10.3.tar.gz

[[email protected] tools]# cd redis-2.10.3/

[[email protected] redis-2.10.3]# python setup.py install

2.5 测试各个驱动是否正常运行（非必须）

在lepus的安装文件包python目录中，找到如下测试文件，测试上述驱动是否安装正确

[[email protected] tools]# unzip Lepus数据库企业监控系统3.7版本官方下载.zip

[[email protected] tools]# cd lepus_v3.7/python/

[[email protected] python]# python test_driver_mysql.py

MySQL python drivier is ok!

[[email protected] python]# python test_driver_oracle.py

Oracle python drivier is ok!

[[email protected] python]# python test_driver_mongodb.py

MongoDB python drivier is ok!

[[email protected] python]# python test_driver_redis.py

Redis python drivier is ok!

 

3、安装Lepus采集器

[[email protected] sql]# systemctl start mariadb.service         #启动服务

[[email protected] sql]# systemctl enable mariadb.service

[[email protected] sql]# mysqladmin -uroot password ‘123456‘    #设置数据库密码

[[email protected] sql]# mysql -uroot -p123456

MariaDB [(none)]> create database lepus default character set utf8;        #创建数据库

MariaDB [(none)]> grant all on lepus.* to [email protected] identified by ‘123456‘;        #授权

MariaDB [(none)]> exit

[[email protected] sql]# mysql -ulepus -p123456 lepus <lepus_table.sql         #导入数据库文件

[[email protected] sql]# mysql -ulepus -p123456 lepus <lepus_data.sql

[[email protected] sql]# cd ../python/

[[email protected] python]# chmod +x install.sh        #为安装脚本添加执行权限

[[email protected] python]# ./install.sh                #安装

[[email protected] python]# cd /usr/local/lepus/

[[email protected] lepus]# vim etc/config.ini            #修改配置文件

[monitor_server]

host="127.0.0.1"

port=3306

user="lepus"

passwd="123456"

dbname="lepus"

[[email protected] lepus]# lepus start                #启动

 

4、安装WEB管理台

[[email protected] lepus]# cd /service/tools/lepus_v3.7/php/

[[email protected] php]# cp -a . /var/www/html/            #拷贝web界面代码

[[email protected] php]# systemctl start httpd.service         #启动服务

[[email protected] php]# systemctl enable httpd.service

[[email protected] html]# vim application/config/database.php        #修改配置文件

$db[‘default‘][‘hostname‘] = ‘127.0.0.1‘;

$db[‘default‘][‘port‘] = ‘3306‘;

$db[‘default‘][‘username‘] = ‘lepus‘;

$db[‘default‘][‘password‘] = ‘123456‘;

$db[‘default‘][‘database‘] = ‘lepus‘;

$db[‘default‘][‘dbdriver‘] = ‘mysql‘;

通过浏览器输入IP地址或域名打开监控界面，即可登录系统。.默认管理员账号密码admin/Lepusadmin登录后请修改管理员密码，增加普通账号。

 

5、添加监控数据库实例

配置中心——>mysql——>新增

[[email protected] html]# tail -f /usr/local/lepus/logs/lepus.log        #查看日志，成功添加监控

 

6、添加操作系统snmp监控实例

[[email protected] html]# yum install -y net-snmp        #安装net-snmp

[[email protected] html]# vim /etc/snmp/snmpd.conf        #修改配置文件，增加一行

view systemview included .1

[[email protected] html]# systemctl start snmpd.service     #启动服务

[[email protected] html]# systemctl enable snmpd.service     

[[email protected] html]# netstat -lntup|grep 161
