• redis requires Ruby version >= 2.2.2.


    安装RVM

    无法在服务器使用curl命令访问https域名,原因是nss版本有点旧了,yum -y update nss更新一下

    yum -y update nss

    新建rvm-installer.sh

    chmod +x rvm-installer.sh

    ./rvm-installer.sh

    安装一个ruby版本
    rvm install 2.3.3

    使用一个ruby版本
    rvm use 2.3.3

    #!/usr/bin/env bash

    Options
    
      [[--]version] <version>
    
        The version or tag to install. Valid values are:
    
          latest         - The latest tagged version.
          latest-minor   - The latest minor version of the current major version.
          latest-<x>     - The latest minor version of version x.
          latest-<x>.<y> - The latest patch version of version x.y.
          <x>.<y>.<z>    - Major version x, minor version y and patch z.
    
      [--]branch <branch>
    
        The name of the branch from which RVM is installed. This option can be used
        with the following formats for <branch>:
    
          <account>/
    
            If account is wayneeseguin or mpapis, installs from one of the following:
    
              https://github.com/rvm/rvm/archive/master.tar.gz
              https://bitbucket.org/mpapis/rvm/get/master.tar.gz
    
           Otherwise, installs from:
    
             https://github.com/<account>/rvm/archive/master.tar.gz
    
          <account>/<branch>
    
            If account is wayneeseguin or mpapis, installs from one of the following:
    
              https://github.com/rvm/rvm/archive/<branch>.tar.gz
              https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz
    
            Otherwise, installs from:
    
              https://github.com/<account>/rvm/archive/<branch>.tar.gz
    
          [/]<branch>
    
            Installs the branch from one of the following:
    
              https://github.com/rvm/rvm/archive/<branch>.tar.gz
              https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz
    
          [--]source <source>
    
            Defines the repository from which RVM is retrieved and installed in the format:
    
              <domain>/<account>/<repo>
    
            Where:
    
              <domain>  - Is bitbucket.org, github.com or a github enterprise site serving
                          an RVM repository.
              <account> - Is the user account in which the RVM repository resides.
              <repo>    - Is the name of the RVM repository.
    
            Note that when using the [--]source option, one should only use the [/]branch format
            with the [--]branch option. Failure to do so will result in undefined behavior.
    
          --trace
    
            Provides debug logging for the installation script.
    Actions
    
      master - Installs RVM from the master branch at rvm/rvm on github or mpapis/rvm
               on bitbucket.org.
