Linux下安装MySQLdb模块
进入python的命令行,输入 import MySQLdb 如果没有报错,证明此模块已经安装,可以跳过以下步骤。
1,查看是否已安装MySQLdb模块
进入python的命令行,输入 import MySQLdb 如果没有报错,证明此模块已经安装,可以跳过以下步骤。
2,下载最新的MySQLdb安装包:
wget -O python-1.2.3c1.tar.gz
tar xzvf python-1.2.3c1.tar.gz
cd MySQL-python-1.2.3c1
3,进入用户MySQLdb源码目录,运行 python setup.py build。
报错:ImportError: No module named setuptools
解决:安装setuptools
wget -O setuptools-0.6c8.tar.gz
tar xzvf setuptools-0.6c8.tar.gz
cd setuptools-0.6c8
python setup.py build
sudo python setup.py install
报错:mysql_config not found
原因:mysql_config命令没有找到。
解决:
1)使用whereis mysql命令找到mysql安装目录,假设mysql安装在/usr/local/mysql
2) 回到MySQLdb源码目录, vi setup_posix.py 或 vimsetup_posix.py打开配置文件,找到mysql_config.path一行,把路径改为mysql安装路径下bin目录,即mysql_config.path ="/usr/local/mysql/bin/mysql_config"。
如果MySQL安装在系统默认路径下,mysql_config脚本文件位于"/usr/bin/mysql_config"。(如果没有mysql_config,则需要安装mysql-dev包)
报错: /usr/bin/ld: cannot find -lmysqlclient_r
解决:
切换到root用户,执行echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf#请主意这个/etc/ld.so.conf,这个是ld的默认配置文件,视系统不同而不同。/usr/local/mysql/lib/mysql与mysql安装目录相关。
强制刷新ld的配置文件。使用:ldconfig
进入mysql的lib目录如/usr/local/mysql/lib/mysql #与mysql安装目录相关。
如果没有libmysqlclient_r.so 就建立一个软连接 ln -s libmysqlclient.so libmysqlclient_r.so
退出root,切换到当前用户.
报错: _mysql.c:2810: error: expected declaration specifiers before 'init_mysql'
解决:安装python-dev,yum install python-devel
4,,进入用户MySQLdb源码目录,运行sudo python setup.py install
