新伺服器配置

筆記

更新apt-get:

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

安裝C編譯(必須):

部分伺服器廠商沒有, 阿裡雲騰訊雲谷歌雲亞馬遜都預裝了

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

安裝python(部分新伺服器沒有)

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

遇到的錯誤

1. 如果遇到以下錯誤:

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

   将上面代碼換成:

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

2. 在pip 安裝MySQL-python 會遇到以下錯誤

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

   隻需要提前安裝下:
3. 遇到下面問題:

   Warning: (, 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問題:

   檢視gunicorn程序
       pstree -ap|grep gunicorn
       重新開機gunicorn
       kill -HUP (程序ID)
              

   如果沒有pstree指令

   sudo apt-get install psmisc
