天兔（Lepus 3.8）数据库监控系统部署

一、安装LAMP基础环境

首先向大家阐述LAMP(Linux+Apache+MySQL +PHP)基础环境配置。

配置LAMP基础环境的方式有很多种，最简单的方式有yum安装、RPM包安装等方式、安装集成环境包(例如lampp/xampp等)。您也可以手动编译安装相关软件。这里我们不推荐使用YUM进行安装，YUM安装的PHP环境可以因为缺少某些依赖包导致500错误。如果你有能力，可以进行编译安装，按照需要的模块编译PHP和MYSQL数据库，这种方式也是目前大型WEB推荐的方式。如果你无法进行编译安装，我们推荐你使用Xampp集成环境包进行安装，xampp是一个可靠的稳定的lamp套件，目前已被诸多公司用于生产服务器的部署，目前Lepus的开发环境，测试环境以及线上官网的WEB环境，都是运行在xampp环境下面，并且一直都是稳定的。

Xampp下载地址：https://www.apachefriends.org/download.html

Xampp帮助文档：https://www.apachefriends.org/faq_linux.html

PS：注意你的版本号，高版本的XAMPP中不是MySQL而是MariaDB。

基础环境

$ uname -r
3.10.0-327.28.3.el7.x86_64
$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)

$ uname -r

3.10.0-327.28.3.el7.x86_64

$ cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

安装XAMPP

对于安装XAMPP需要特别注意，lepus目前版本3.7和3.8好像只对PHP 5支持比较完美，所以安装XAMPP时最好安装5.5的版本，本人测试了PHP 5.5、PHP 5.6、PHP 7.2只有PHP5可用，并且对于PHP 7连驱动程序都要改变一下。如果你不想踩坑，最好所有软件版本对应本博客来搭建lepus。当然，后面可能会支持更高版本的PHP，这个需要你进行测试。

$ wget https://sourceforge.net/projects/xampp/files/XAMPP%20Linux/5.5.38/xampp-linux-x64-5.5.38-3-installer.run
$ chmod +x xampp-linux-x64-5.5.38-3-installer.run
$ ./xampp-linux-x64-5.5.38-3-installer.run

追加环境变量（可执行文件、库文件和头文件）

$ cat /etc/profile
export PATH=$PATH:/opt/lampp/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/lampp/lib
export C_INCLUDE_PATH=$C_INCLUDE_PATH:/opt/lampp/include

$ cat /etc/profile

export PATH=$PATH:/opt/lampp/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/lampp/lib

export C_INCLUDE_PATH=$C_INCLUDE_PATH:/opt/lampp/include

$ source /etc/profile

1	$ source /etc/profile

启动LAMP

$ /opt/lampp/lampp start
Starting XAMPP for Linux 5.5.38-3...
XAMPP: Starting Apache...ok.
XAMPP: Starting MySQL...ok.
XAMPP: Starting ProFTPD...ok.

$ /opt/lampp/lampp start

Starting XAMPP for Linux 5.5.38-3...

XAMPP: Starting Apache...ok.

XAMPP: Starting MySQL...ok.

XAMPP: Starting ProFTPD...ok.

PS：lampp命令支持stop、status、start、restart命令。

让xampp开机自动启动

$ ln -s /opt/lampp/lampp /etc/init.d/lampp
$ chkconfig --add lampp

1 2	$ ln -s /opt/lampp/lampp /etc/init.d/lampp $ chkconfig --add lampp

简单介绍一下XAMPP组件配置

# HTTPD主配置文件;
/opt/lampp/etc/httpd.conf

# PHP主配置文件;
/opt/lampp/etc/php.ini

# MariaDB主配置文件;
/opt/lampp/etc/my.cnf

# MariaDB数据目录;
/opt/lampp/var/mysql

# 所有日志目录;
/opt/lampp/logs/

# HTTPD主配置文件;

/opt/lampp/etc/httpd.conf

# PHP主配置文件;

# MariaDB主配置文件;

/opt/lampp/etc/my.cnf

# MariaDB数据目录;

/opt/lampp/var/mysql

# 所有日志目录;

/opt/lampp/logs/

PS：如果想重新安装，只需要删除/opt/lampp即可。

二、安装Python基础模块

首先安装Python环境（Python版本要求为Python2.6以上,不支持Python3）

其次安装数据库连接Python的驱动包

1. 安装MySQLdb for python （必须安装）

MySQLdb为Python连接和操作MySQL的类库，如果您准备使用lepus系统监控MySQL数据库，那么该模块必须安装。

$ wget http://cdn.lepus.cc/cdncache/software/MySQLdb-python.zip
$ unzip MySQLdb-python.zip 
$ cd MySQLdb1-master/ 
$ which mysql_config 
/opt/lampp/bin/mysql_config
$ vim site.cfg
mysql_config = /opt/lampp/bin/mysql_config
$ yum install gcc libffi-devel python-devel openssl-devel urpmi xterm
$ python setup.py build 
$ python setup.py install

$ wget http://cdn.lepus.cc/cdncache/software/MySQLdb-python.zip

$ unzip MySQLdb-python.zip

$ cd MySQLdb1-master/

$ which mysql_config

/opt/lampp/bin/mysql_config

$ vim site.cfg

mysql_config = /opt/lampp/bin/mysql_config

$ yum install gcc libffi-devel python-devel openssl-devel urpmi xterm

$ python setup.py build

$ python setup.py install

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

pymongo为Python连接和操作MongoDB的类库，如果您准备使用lepus系统监控MongoDBs数据库，那么该模块必须安装。

安装步骤如下:

$ wget http://cdn.lepus.cc/cdncache/software/pymongo-2.7.tar.gz 
$ tar zxvf pymongo-2.7.tar.gz 
$ cd pymongo-2.7 
$ python setup.py install

$ wget http://cdn.lepus.cc/cdncache/software/pymongo-2.7.tar.gz

$ tar zxvf pymongo-2.7.tar.gz

$ cd pymongo-2.7

$ python setup.py install

3. 安装Redis 驱动（如果需要监控Redis则必须安装）

$ wget http://cdn.lepus.cc/cdncache/software/redis-py-2.10.3.tar.gz
$ tar zxvf redis-py-2.10.3.tar.gz 
$ cd redis-2.10.3/ 
$ python setup.py install

$ wget http://cdn.lepus.cc/cdncache/software/redis-py-2.10.3.tar.gz

$ tar zxvf redis-py-2.10.3.tar.gz

$ cd redis-2.10.3/

$ python setup.py install

4. 测试各个驱动是否正常运行

$ python test_driver_mysql.py 
MySQL python drivier is ok!
$ python test_driver_mongodb.py
MongoDB python drivier is ok!
$ python test_driver_redis.py 
Redis python drivier is ok!

$ python test_driver_mysql.py

MySQL python drivier is ok!

$ python test_driver_mongodb.py

MongoDB python drivier is ok!

$ python test_driver_redis.py

Redis python drivier is ok!

三、安装Lepus 3.8采集器

关于Lepus3.8版本的一些说明

安装Lepus监控系统，在安装Lepus系统之前，请先根据前面内容安装LAMP和Python运行基础环境。

1）上传软件包到监控机服务器并解压缩软件到您的系统

$ unzip Lepus3.8_Beta.zip
$ cd Lepus_v3.8_beta

1 2	$ unzip Lepus3.8_Beta.zip $ cd Lepus_v3.8_beta

2）在监控机创建监控数据库并授权

mysql> create database lepus default character set utf8;
mysql> grant select,insert,update,delete,create on lepus.* to 'lepus_user'@'localhost' identified by '123456';
mysql> grant select,insert,update,delete,create on lepus.* to 'lepus_user'@'%' identified by '123456';
mysql> flush privileges;

mysql> create database lepus default character set utf8;

mysql> grant select,insert,update,delete,create on lepus.* to 'lepus_user'@'localhost' identified by '123456';

mysql> grant select,insert,update,delete,create on lepus.* to 'lepus_user'@'%' identified by '123456';

mysql> flush privileges;

导入SQL文件夹里的SQL文件(表结构和数据文件)

$ mysql lepus < sql/lepus_table.sql
$ mysql lepus < sql/lepus_data.sql

1 2	$ mysql lepus < sql/lepus_table.sql $ mysql lepus < sql/lepus_data.sql

4）安装Lpeus程序

进入到软件包的python文件夹

$ cd python/

1	$ cd python/

授予install.sh可执行权限

$ chmod +x install.sh

1	$ chmod +x install.sh

执行安装

$ ./install.sh 
[note] lepus will be install on basedir: /usr/local/lepus
[note] /usr/local/lepus directory does not exist,will be created.
[note] /usr/local/lepus directory created success.
[note] wait copy files.......
[note] change script permission.
[note] create links.
[note] install complete.

$ ./install.sh

[note] lepus will be install on basedir: /usr/local/lepus

[note] /usr/local/lepus directory does not exist,will be created.

[note] /usr/local/lepus directory created success.

[note] wait copy files.......

[note] change script permission.

[note] create links.

[note] install complete.

5）修改配置文件

进入到安装目录，默认为/usr/local/lepus。

$ cd /usr/local/lepus/
$ cat etc/config.ini 
###监控机MySQL数据库连接地址###
[monitor_server]
host="127.0.0.1"
port=3306
user="lepus_user"
passwd="123456"
dbname="lepus"

$ cd /usr/local/lepus/

$ cat etc/config.ini

###监控机MySQL数据库连接地址###

[monitor_server]

host="127.0.0.1"

port=3306

user="lepus_user"

passwd="123456"

dbname="lepus"

6）启动Lepus （可选）

此时，你可以执行启动命令启动lepus采集进程。

$ lepus start
lepus server start success!
$ lepus status
lepus server is running...

$ lepus start

lepus server start success!

$ lepus status

lepus server is running...

但是因为没有添加主机，所以查看日志会看到如下提示，属于正常提示。您也可以在部署完Lepus WEB控制台后再进行启动。

$ tail -f logs/lepus.log 
2017-02-09 18:57:19 [INFO] check mysql controller started.
2017-02-09 18:57:19 [WARNING] check mysql: not found any servers
2017-02-09 18:57:19 [INFO] check mysql controller finished.
2017-02-09 18:57:37 [INFO] alarm controller started.
2017-02-09 18:57:37 [INFO] alarm controller finished.
2017-02-09 18:58:20 [INFO] check mysql controller started.
2017-02-09 18:58:20 [WARNING] check mysql: not found any servers
2017-02-09 18:58:20 [INFO] check mysql controller finished.
2017-02-09 18:58:20 [INFO] check mysql controller finished.

$ tail -f logs/lepus.log

2017-02-09 18:57:19 [INFO] check mysql controller started.

2017-02-09 18:57:19 [WARNING] check mysql: not found any servers

2017-02-09 18:57:19 [INFO] check mysql controller finished.

2017-02-09 18:57:37 [INFO] alarm controller started.

2017-02-09 18:57:37 [INFO] alarm controller finished.

2017-02-09 18:58:20 [INFO] check mysql controller started.

2017-02-09 18:58:20 [WARNING] check mysql: not found any servers

2017-02-09 18:58:20 [INFO] check mysql controller finished.

Lepus采集程序安装完毕!

四、安装WEB管理台

复制PHP文件夹里的文件到Apache对应的网站虚拟目录（备注：根本不同的安装方式，这个目录是不一样的，如果采用xampp安装的Apache环境，则默认程序目录为/opt/lampp/htdocs/），例如：

$ cp -fr /root/lepus/Lepus_v3.8_beta/php/* /opt/lampp/htdocs/

1	$ cp -fr /root/lepus/Lepus_v3.8_beta/php/* /opt/lampp/htdocs/

打开application/config/database.php文件，修改PHP连接监控服务器的数据库信息.

$ cat /opt/lampp/htdocs/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';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
