Lepus安裝需要Lamp環境，Lamp環境的安裝個人認為比較費勁，XAMPP的一鍵部署LAMP環境省心省力， lepus官網手冊也建議採用XAMPP的方式安裝，lepus也是在XAMPP上進行研發的，看官網安裝手冊，看了半天也沒成功，經過多日奮戰，終於實現lepus的快速，輕量化部署，並能用ie瀏覽器監控。

注意xampp會把apache，mysql，php都安裝，所以要在乾淨的環境中進行安裝，以免安裝兩個mysql，兩個mysql也是可以的，我這裡是乾淨的環境。

整體環境：

192.168.1.250 HE3 監控機

192.168.1.248 HE1 主 被監控機

192.168.1.249 HE2 從 被監控機

安裝XAMPP

Xampp下載地址：https://www.apachefriends.org/download.html

注意你的版本號，高版本的XAMPP中可能不是Mysql而是MariaDB

[[email protected]]# chmod +x xampp-linux-x64-1.8.2-5-installer.run

[[email protected]]# ./xampp-linux-x64-1.8.2-5-installer.run

[[email protected]]# /opt/lampp/lampp start

[[email protected]

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

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

[[email protected]]#source /etc/profile

下載MySQLdb-python.zip是lepus安裝後監控mysql所必需的

[[email protected] home]#wget http://cdn.lepus.cc/cdncache/software/MySQLdb-python.zip

[[email protected]

[[email protected] home]# cd MySQLdb1-master/

[[email protected]]# which mysql_config

/opt/lampp/bin/mysql_config

[[email protected]]# vi site.cfg

mysql_config= /opt/lampp/bin/mysql_config

[[email protected]~]#yum install gcc libffi-devel python-devel openssl-devel

[[email protected]~]# yum install urpmi xterm

[[email protected]]# python setup.py build

[[email protected]]# python setup.py install

注：lepus安裝過程中如果報錯，根據報錯資訊來操作比如

[[email protected]]# ln -s /usr/lib64/libssl.so.1.0.1e /usr/lib64/libssl.so.1.0.0

[[email protected]]# ln -s /usr/lib64/libcrypto.so.1.0.1e /usr/lib64/libcrypto.so.1.0.0

lepus安裝採集器（lepus官網下載）

[[email protected] home]#unzip lepus3.7.zip

監控庫

mysql> create database lepus default character set utf8;

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

mysql> flush privileges;

[[email protected]_v3.7]# mysql -uroot -p lepus < sql/lepus_table.sql

[[email protected]_v3.7]# mysql -uroot -p lepus < sql/lepus_data.sql

mysql>use lepus

mysql>alter table mysql_status modify column max_connect_errors bigint(18);

mysql>alter table mysql_status_history modify column max_connect_errors bigint(18);

被監控庫HE1,HE2只需建立lepus_monitor賬號即可

mysql> grant select,super,process,reload,show databases,replication client on *.* to'lepus_monitor'@'%' identified by 'MANAGER';

mysql> flush privileges;

[[email protected]_v3.7]# cd python/

[[email protected] python]#chmod +x install.sh

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

[[email protected] python]#vi /usr/local/lepus/etc/config.ini

[monitor_server]
host="192.168.1.250"
port=3306
user="lepus_user"
passwd="MANAGER"
dbname="lepus"

[[email protected]_v3.7]# cp -r php/* /opt/lampp/htdocs/

[[email protected]_v3.7]# vi /opt/lampp/htdocs/application/config/database.php

$db['default']['hostname']= '192.168.1.250';
$db['default']['port']     = '3306';
$db['default']['username']= 'lepus_user';
$db['default']['password']= 'MANAGER';
$db['default']['database']= 'lepus';
$db['default']['dbdriver']= 'mysql';

[[email protected]_v3.7]# cd /usr/local/lepus/

[[email protected] lepus]#lepus start

nohup: appendingoutput to `nohup.out'

lepus server startsuccess!

有問題看日誌

[[email protected] ~]# tail -f /usr/local/lepus/nohup.out 

[[email protected] ~]# tail -f /usr/local/lepus/logs/lepus.log

[[email protected]~]# vi /opt/lampp/etc/extra/httpd-vhosts.conf

刪除原有的，改為

<VirtualHost*:80>
    AddDefaultCharset UTF-8
    DocumentRoot "/opt/lampp/htdocs"
    ServerName mysqlmtop1.ikongjian.com
    <Directory"/opt/lampp/htdocs">
        Options FollowSymLinks
        AllowOverride All
        Order allow,deny
        Allow from All
    </Directory>
    ErrorLog"|/usr/local/apache/bin/rotatelogs /home/logs/apache/php_%Y%m%d_error.log86400 480"
    CustomLog"|/usr/local/apache/bin/rotatelogs /home/logs/apache/php_%Y%m%d_access.log86400 480" common
</VirtualHost>

[[email protected]~]# vi /etc/hosts

127.0.0.1   localhost localhost.localdomain

::1         localhost6 localhost6.localdomain6

192.168.1.248   HE1

192.168.1.249   HE2

192.168.1.250   HE3 mysqlmtop1.ikongjian.com

192.168.1.251   HE4

通過瀏覽器輸入mysqlmtop1.ikongjian.com開啟監控介面，即可登入系統。預設管理員賬號密碼admin/Lepusadmin登入後請修改管理員密碼，增加普通賬號。

讓xampp開機自動啟動

sudo ln -s /opt/lampp/lampp /etc/init.d/lampp

sudo chkconfig --add lampp

編輯windows中的hosts

C:\Windows\System32\drivers\etc

新增

192.168.1.250   mysqlmtop1.ikongjian.com

就可以在ie瀏覽器中進行操作了

------------------------------------------------BUG fix--------------------------------------------

---------------------redis----------------------

[[email protected] lepus]#vi check_redis.py

149     except Exception, e:
150         logger_msg="check redis %s:%s : %s" %(host,port,e)
151         #logger.warning(logger_msg)

155             sql="insert into redis_status(server_id,host,port,tags,connect) values(%    s,%s,%s,%s,%s)"

151行的註釋掉就解決redis不能監控slave的bug了

--------------------mysql複製監控圖異常--------------------

---MySQL複製監控中無法看圖形

vi/opt/lampp/htdocs/application/controllers/lp_mysql.php

337行，去掉'mysql/replication'，改為parent::check_privilege();

原來為parent::check_privilege('mysql/replication'）;

---修復mysql複製圖表時間偏移導致資料不準確

影響：線型圖表時間偏移

修復：修改vi/opt/lampp/htdocs/application/controllers/lp_mysql.php

352行找到public function replication()的$chart_reslut[$i]['delay']=$dbdata['delay']，修該為：

$chart_reslut[$i]['delay']= !empty($dbdata['delay']) ? $dbdata['delay'] : 0;
