在装完MySQL和Navicat之后我以为所有困难都过去了,下个包跑一下setup.py,Python就该乖乖听我的连数据库了……我错了
现在虽然配好了,说实话脑子还是很混乱,不知道到底哪些是有效操作,总之都先写上
① 下载MySQLdb,此时此刻下到的最新版是MySQL-python-1.2.5.zip
https://pypi.python.org/pypi/MySQL-python/
② 解压,修改里面的site.cfg文件,把mysql_config注释去掉,路径改成/usr/local/mysql/bin/mysql_config(←如果mysql是默认安装位置的话)
③ 此时运行sudo python setup.py install或者build报了个error: command 'cc' failed with exit status 1 ,如下图所示
④ 我在网上找到的解决办法都飒爽地这么回答:
<code><span><span><span>export CFLAGS</span></span><span><span>=-</span></span><span><span>Qunused</span></span><span><span>-</span></span><span><span>arguments export CPPFLAGS</span></span><span><span>=-</span></span><span><span>Qunused</span></span><span><span>-</span></span><span><span>arguments</span></span></span></code>然后就是一个pip命令……我没装啊亲QAQ
不过还是把这两行加到了那个传说中的~/.bash_profile文件,也不知道这样做对不对
④ 仍然各种报错。
包括还是cc有问题,找不到mysql_config,Reason: image not found,easy_install下载文件是None之类的
于是我把所有参考的文章里的方法都试了个遍,操作了以下4条
<span style="font-size:18px;">sudo n -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/</span>
终于成功……虽然报了很多warning
总而言之即使配置成功了我也仍旧稀里糊涂的。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
