新服务器配置

笔记

更新apt-get:

• sudo apt-get upgrade
• sudo apt-get update

安装C编译(必须):

部分服务器厂商没有, 阿里云腾讯云谷歌云亚马逊都预装了

• sudo apt-get install gcc;
• sudp apt-get install g++;
• sudo apt-get install make

安装python(部分新服务器没有)

• sudo apt-get install python2.7
• sudo apt-get install python3.5(目前遇到的服务器都有3.x版本)
• sudo apt-get install python-pip
• sudo apt-get install python3-pip
• pip install –upgrade pip

遇到的错误

1. 如果遇到以下错误:

   Traceback (most recent call last):
     File "/usr/bin/pip", line 9, in <module>
       from pip import main
   ImportError: cannot import name main

   将上面代码换成:

   from pip import __main__
   if __name__ == '__main__':
       sys.exit(__main__._main())

2. 在pip 安装MySQL-python 会遇到以下错误

   Traceback (most recent call last):
         File "<string>", line 1, in <module>
         File "/tmp/pip-install-qI3fAK/MySQL-python/setup.py", line 17, in <module>
           metadata, options = get_config()
         File "setup_posix.py", line 43, in get_config
           libs = mysql_config("libs_r")
         File "setup_posix.py", line 25, in mysql_config
           raise EnvironmentError("%s not found" % (mysql_config.path,))
       EnvironmentError: mysql_config not found
   

   只需要提前安装下:

   sudo apt-get install libmysqlclient-dev

3. 遇到下面问题:

    Warning: (1287L, u"'@@tx_isolation' is deprecated 
   and will be removed in a future release. Please use'@@transaction_isolation' instead")
     cursor.execute('SELECT @@tx_isolation')

4. gunicorn问题:

       查看gunicorn进程
       pstree -ap|grep gunicorn
       重启gunicorn
       kill -HUP 30080(进程ID)

   如果没有pstree命令

   sudo apt-get install psmisc
