centos7搭建天兔
如果新系统尚未安装工具pip，可通过以下三步快速安装pip
1. yum -y install epel-release
2. yum -y install python-pip
3. pip --version 查看pip版本
若要更新pip，可以使用命令pip install --upgrade pip
pip install pymongo redis mysql-python ：安装python驱动
mysql> grant all privileges on *.* to 'lepus_user'@'%' identified by '123456';
#允许单个ip 修改用户名和密码为你自己的
mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
#最后
mysql> FLUSH PRIVILEGES;
这里的123456为你给新增权限用户设置的密码，%代表所有主机，也可以具体到你的主机ip地址
2.flush privileges; 这一步一定要做，不然无法成功！ 这句表示从mysql数据库的grant表中重新加载权限数据
一、安装LAMP基础环境
1.
xampp:下载访问地址：https://sourceforge.net/projects/xampp/
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
$ ln -s /opt/lampp/lampp /etc/init.d/lampp （添加软链接）
$ ln -s /opt/lampp/lampp /etc/init.d/lampp （添加软链接）
$ chkconfig --add lampp
1.unzip lepus3.7.zip
unzip Lepus.zip
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 lepus < sql/lepus_data.sql
mysql> grant select,super,process,reload,show databases,replication client on *.* to'lepus_monitor'@'%' identified by 'MANAGER';
mysql> flush privileges;
5.安装Lpeus程序
进入到软件包的python文件夹:cd python/
通过浏览器输入网址如：http://192.168.100.198/lepus，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。
4.5.新版本有权限问题，需要配置一下：
步骤： cd /opt/lampp/etc/extra
vim httpd-xampp.conf
找到#
<Directory "/opt/lampp/phpmyadmin">
AllowOverride AuthConfig Limit
Require localhost
ErrorDocument /error/XAMPP_FORBIDDEN.html.var
</Directory>
将其中的"Require localhost"改为"Require all granted"
保存，重启Xampp即可~
五.进行redis监控，监控机（不是被监控机）要安装redis驱动：
$ 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
六.数据库慢查询配置：
天兔安装的数据库，数据库的配置文件为：/opt/lampp/etc/my.cnf
使用命令：mysql --help :可以显示数据库配置文件位置
天兔安装的数据库，数据库的mysql目录为：/opt/lampp/var/mysql/
默认的慢查询日志：localhost-slow.log 就是在这个目录下，实际慢查询记录的日志文件为：/opt/lampp/var/mysql/localhost-slow.log
修改数据库配置文件配置慢查询：
永久开启慢查询，需要修改/opt/lampp/etc/my.cnf文件
cd /opt/lampp/etc/
vim my.cnf
原配置内容：
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/lampp/var/mysql) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option. # The following options will be passed to all MySQL clients
[client]
#password = your_password

#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# ) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# ) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to

# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown

加上慢查询配置，在[mysqld]下添加配置：
slow_query_log = ON
slow_query_log_file = /opt/lampp/var/mysql/slow_query.log （此处可以先不配置此项，使用默认即可）
long_query_time = 1

步骤一：
1.查看Mariadb数据库慢查询是否开启：
mysql
show variables like 'log_slow_queries'; (如果结果为ON则是开启了，如果为OFF则表示禁用了。) ---mysql查询命令
show variables like 'slow_query%'; ----Mariadb查询命令（可以查询慢查询开启状态及慢查询的日志名称）
show variables like 'slow_query_log'; ----Mariadb查询命令（Mariadb慢查询的日志的变量名为slow_query_log）
2.设置慢查询：
set global log_slow_queries = on; ---mysql设置开启慢查询日志命令
set global slow_query_log = on; ---Mariadb设置开启慢查询日志命令
flush hosts; ---使配置生效命令
3.查询慢查询开启状态：
设置后重新使用 mysql 命令进入数据库查看慢查询设置
mysql
show variables like 'log_slow_queries'; (如果结果为ON则是开启了，如果为OFF则表示禁用了。) ---mysql查询命令
show variables like 'slow_query_log'; ----Mariadb查询命令（Mariadb慢查询的日志的变量名为slow_query_log）
4.查看慢查询设置的时间：
show global variables like 'long_query_time'; （默认设置为10秒）
show variables like 'long_query_%';
5.设置慢查询时间：
set global long_query_time =1; （将慢查询时间设置为1秒）
6.设置慢查询日志路径：
set global slow_query_log_file='/opt/lampp/var/mysql/slow_query.log'; #此处一定要设置到文件slow_query.log，不能只设置到路径，否者报错
6.测试慢查询：
select sleep(2); （查询2秒）
在监控机（即安装天兔服务的机子）：
which pt-query-digest
显示：
/usr/local/bin/pt-query-digest
查看mysql客户端位置：
which mysql
出现如：
/opt/lampp/bin/mysql
1.进入到 lepus_slowquery.sh文件所在的 目录下：
cd /usr/local/lepus/client/mysql/
cat lepus_slowquery.sh
2.将 lepus服务器（及监控机）下的lepus_slowquery.sh （即/usr/local/lepus/client/mysql/lepus_slowquery.sh）文件copy到被监控机（不是监控机）下 的 /usr/local/sbin/ 目录下
如果监控机和被监控机时同一个机子，可以使用命令：
cp lepus_slowquery.sh /usr/local/sbin/
3.编辑 /usr/local/sbin/下的lepus_slowquery.sh：（被监控机上的配置）
3.1.被监控机:需要安装percona-toolkit工具进行慢查询日志的统计
使用命令安装：yum groupinstall perl* （不安装解析会有问题）
PT工具安装：
下载地址：https://www.percona.com/downloads/percona-toolkit/2.2.20/deb/percona-toolkit_2.2.20-1.tar.gz
https://www.percona.com/downloads/percona-toolkit/LATEST/ 选择2.2.6版本
wget http://www.percona.com/get/percona-toolkit.tar.gz
下载成功后上传到centos7系统：
rz 上传文件名 ：上传即可
然后，解压运行，命令：
[root@HE1~]## yum -y install perl-IO-Socket-SSL
[root@HE1~]## yum -y install perl-DBI
[root@HE1~]## yum -y install perl-DBD-MySQL
[root@HE1~]## yum -y install perl-Time-HiRes
[root@HE1~]# tar xvf percona-toolkit-2.2.12.tar.gz
[root@HE1~]# cd percona-toolkit-2.2.12
[root@HE1percona-toolkit-2.2.12]# perl Makefile.PL
报错解决方案：
安装缺少的包
yum install perl-DBD-MySQL
然后，重新编译
perl
Makefile.PL
Writing Makefile for percona-toolkit
继续
make && make test && make install （直接用make && make install，不加make test也可以，如果加make test报错的话）
报错解决方法：blog.sina.com.cn/s/blog_616b428f01018fry.html
[root@HE1percona-toolkit-2.2.12]# make && make install
下载 percona-toolkit-2.2.6-1.noarch.rpm文件后，上传到系统：
安装命令：rpm -ivh percona-toolkit-2.2.6-1.noarch.rpm
which pt-query-digest
显示：
/usr/local/bin/pt-query-digest
查看mysql客户端位置：
which mysql
出现如：
/opt/lampp/bin/mysql
3.2.安装pt-query-diges完成后，配置被监控机上的/usr/local/sbin/lepus_slowquery.sh文件
vim /usr/local/sbin/lepus_slowquery.sh
#!/bin/bash
#****************************************************************#
# ScriptName: /usr/local/sbin/lepus_slowquery.sh

cd $slowquery_dir
/usr/bin/find ./ -name 'slowquery_*' -mtime +|xargs rm -rf ; ####END####
:wq!：保存退出
cd /usr/local/sbin/ :进入目录
chmod +x lepus_slowquery.sh ：设置可执行权限,如果已经是可执行权限，可以不设置
./lepus_slowquery.sh :运行一下，看看效果（手动运行查看是否正常运行：sh /usr/local/sbin/lepus_slowquery.sh）
3.3.被监控机配置定时任务，定时统计产生慢查询日志：
查看所有定时任务： crontab -l
添加定时任务： crontab -e
*/5 * * * * sh /usr/local/sbin/lepus_slowquery.sh > /dev/null 2>&1
:wq!：保存退出
3.4. 查看被监控机 /opt/lampp/var/mysql/ （慢查询日志根目录）下是否有生成 类似于这种 slowquery_2019111516.log 的日志
如果有，说明慢查询统计生效
4.在被监控机上开启并可以统计慢查询日志后，在监控机（即搭建天兔服务的机子）上 配置表空间分析:
4.1.在 /usr/local/lepus/lepus.py 文件中，在monitor_mysql中添加(注意python代码格式)：
job = Process(target = job_run, args = ('check_mysql_bigtable',int(frequency_monitor)*)
joblist.append(job)
job.start()
未添加时的代码如下;
def main():
logger.info("lepus controller start.")
monitor = str(func.get_option('monitor'))
monitor_mysql = str(func.get_option('monitor_mysql'))
monitor_mongodb = str(func.get_option('monitor_mongodb'))
monitor_oracle = str(func.get_option('monitor_oracle'))
monitor_redis = str(func.get_option('monitor_redis'))
monitor_os = str(func.get_option('monitor_os'))
alarm = str(func.get_option('alarm'))
frequency_monitor = func.get_option('frequency_monitor')
frequency_monitor_alarm = int(frequency_monitor)+ joblist = []
if monitor=="":
if monitor_mysql=="":
job = Process(target = job_run, args = ('check_mysql',frequency_monitor))
joblist.append(job)
job.start() time.sleep()
if monitor_oracle=="":
job = Process(target = job_run, args = ('check_oracle',frequency_monitor))
joblist.append(job)
job.start()
添加后的代码如下：
def main():
logger.info("lepus controller start.")
monitor = str(func.get_option('monitor'))
monitor_mysql = str(func.get_option('monitor_mysql'))
monitor_mongodb = str(func.get_option('monitor_mongodb'))
monitor_oracle = str(func.get_option('monitor_oracle'))
monitor_redis = str(func.get_option('monitor_redis'))
monitor_os = str(func.get_option('monitor_os'))
alarm = str(func.get_option('alarm'))
frequency_monitor = func.get_option('frequency_monitor')
frequency_monitor_alarm = int(frequency_monitor)+ joblist = []
if monitor=="":
if monitor_mysql=="":
job = Process(target = job_run, args = ('check_mysql',frequency_monitor))
joblist.append(job)
job.start()
job = Process(target = job_run, args = ('check_mysql_bigtable',int(frequency_monitor)*) #添加的部分
joblist.append(job) #添加的部分
job.start() #添加的部分 time.sleep()
if monitor_oracle=="":
job = Process(target = job_run, args = ('check_oracle',frequency_monitor))
joblist.append(job)
job.start()
4.2.监控机（即搭建天兔服务的机子）建立定时任务，定期采集数据，命令：
crontab -e
*/5 * * * * python /usr/local/lepus/check_mysql_bigtable.py
:wq!：保存退出
查看定时任务命令： crontab -l
