linux Basic Configuration
linux environment compiler installation python3 1 way to install the software under. Linux - choice yum utility, convenience, resolve dependencies between the software itself and automatically download and install a configuration yum source (that is, a depot, which put a bunch. rpm package) can choose to Ali cloud sources, Tsinghua yum source configuration of a warehouse, there are a lot of system software used wget -O /etc/yum.repos.d/CentOS-Base.repo HTTP: //mirrors.aliyun. COM / repo / Centos-7 .repo have to configure a second warehouse, carrying a large number of third-party software (nginx, redis, mongodb, mairadb etc.) wget -O /etc/yum.repos.d/epel.repo HTTP: / /mirrors.aliyun.com/repo/epel-7 .repo 2 . you have to understand yum repository directory cd /etc/yum.repos.d/ # will be asked to identify a yum repo file in this directory first layer warehouse 3Empty the cache yum, yum empty centos official software cache yum Clean All 4 generates a new cache Ali cloud yum. Yum makecache - wget url command in a resource of -apt- GET Ubuntu under the yum - use yum repository, not only You can use third-party warehouse yum, yum, or you can specify an official source (like yum official source mariadb database, the latest software packages) - RPM manual installation, you have to deal with dependency - the freedom to choose the version, and install third-party functionality can be extended way, called source code to compile and install

Step 2: Prepare python3 environments, and virtual environments
- Compile and install python3, address environmental variable

- Download virtualenvwrapper tool
virtualenvwrapper, an upgraded version of the virtual environment tool
View Code1 . Installation, do not activate the virtual environment PIP3 install -i https://pypi.douban.com/ the Simple virtualenvwrapper 2 . Modifying the configuration file, every time you turn on the tool load virtualenvwrapper 1 Open a personal user profile environment variables globally configuration file / etc / profile # each user login take effect the user's personal configuration file ~ / .bash_profile vim ~ / .bash_profile # root landing time, the code reads this file 2 . fill in the following information for you their environmental modification python Export WORKON_HOME = ~ / Envs that # set virtualenv unified management directory Export VIRTUALENVWRAPPER_VIRTUALENV_ARGS = ' --no-Site-Packages ' # add parameters virtualenvwrapper generate a clean environment isolated VIRTUALENVWRAPPER_PYTHON = Export / opt / python367 / bin / python3.6 # Specifies the python interpreter Source /opt/python367/bin/virtualenvwrapper.sh # execute the installation script virtualenvwrapper 3 . At this point you can use this tool to quickly create a virtual environment mkvirtualenv virtual environmental name # to create a virtual environment lsvirtualenv # listed in the virtual environment name workon virtual environment name # activate or switch virtual environment lssitepackages # listed in the module information in a virtual environment, in fact, cdvirtualenv # to enter the virtual environment home directory cdsitepackages # to enter the virtual environment first tripartite module directory
- Use mkvirtualenv command to create a new virtual environment for start crm
mkvirtualenv s23_crm
- Crm copy code into machine linux
