安装Python基础模块


准备环境

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

 

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。

安装步骤如下:

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

# unzip MySQLdb-python.zip 

# cd MySQLdb1-master/ 

# which mysql_config 

/usr/local/mysql/bin/mysql_config 

# vim site.cfg 修改如下: 

mysql_config = /usr/local/mysql/bin/mysql_config 

# python setup.py build 

# python setup.py install 

常见错误解决:

1).如果编译python出现如下问题

/usr/bin/ld: cannot find -lpython2.7 

collect2: ld returned 1 exit status 

error: command 'gcc' failed with exit status 1 

请按如下步骤处理:

A.检查并安装python-devel

# yum -y install python-devel 

B.将libpython2.7.so库文件建立软连接到/usr/lib

32位服务器下执行

# ln -s /usr/local/Python2.7/lib/libpython2.7.so /usr/lib/libpython2.7.so 

64位服务器下执行

# ln -s /usr/local/Python2.7/lib/libpython2.7.so /usr/lib64/libpython2.7.so 

C.检查下/etc/ld.so.conf是否包含/usr/local/Python2.7/lib

#vi /etc/ld.so.conf 添加/usr/local/Python2.7/lib 

#/sbin/ldconfig 

2.安装cx_oracle for python (如果需要监控Oracle则必须安装)

下载安装oracle instant client

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

如果是64位的,请选择.*x86_64.rpm,否则是.*i386.rpm

如果是oracle 9i或更高,请选择Instant Client 11,如果是8或8i,请选择Instant Client 10

[root@westserver software]# rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm 

Preparing… ########################################### [100%] 

1:oracle-instantclient11.########################################### [100%] 

[root@westserver software]# rpm -ivh oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm 

Preparing… ########################################### [100%] 

1:oracle-instantclient11.########################################### [100%] 

[root@westserver software]# rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm 

Preparing… ########################################### [100%] 

1:oracle-instantclient11.########################################### [100%] 



[root@westserver home]# 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 

修改完成后重新加载bash_profile文件

[root@westserver  cx_Oracle-5.1.2]# source ~/.bash_profile

[root@westserver software]# vim /etc/ld.so.conf 加入

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

执行ldconfig生效

[root@westserver software]# ldconfig 

安装cx_oracle

# wget http://cdn.lepus.cc/cdncache/software/cx_Oracle-5.1.2.tar.gz

# tar zxvf cx_Oracle-5.1.2.tar.gz 

# cd cx_Oracle-5.1.2 

# python setup.py build 

# python setup.py install 

3.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 

4.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 

5.安装SQLServer驱动 (如果需要监控SQLServer则必须安装)

安装pymssql需要的包:

freetds(http://www.filewatcher.com/m/freetds-0.82.tar.gz.1596755-0.html)

setuptools(https://pypi.python.org/pypi/setuptools)

pymssql(https://pypi.python.org/pypi/pymssql/)

安装步骤:

A. 安装freetds

#tar zxvf freetds-0.82.tar.gz

#cd freetds-0.82

#./configure –prefix=/usr/local/freetds –with-tdsver=8.0 –enable-msdblib –enable-dbmfix –with-gnu-ld –enable-shared –enable-static

#make && make install

#echo "/usr/local/freetds/lib" » /etc/ld.so.conf.d/freetds.conf

#ldconfig -v

B. 安装setuptools

#tar zxvf setuptools-3.5.1.tar.gz

#cd setuptools-3.5.1

# python setup.py install

C. 安装pymssql

#tar zxvf pymssql-2.1.0.tar.gz

#cd pymssql-2.1.0

#python setup.py install

注:如果不安装freetds,会报如下错误:

error: command ‘gcc’ failed with exit status 1

 

6.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,你可以找到如下测试文件,测试上述驱动是否安装正确。

# python test_driver_mysql.py 

MySQL python drivier is ok! 

# python test_driver_oracle.py 

Oracle python drivier is ok! 

# python test_driver_mongodb.py 

MongoDB python drivier is ok! 

# python test_driver_redis.py 

Redis python drivier is ok!
