centos7 Install Jekyll

安装步骤

参照Jekyll官网

1. 安装rvm前需要先导入官网密钥，才能下载安装

gpg2 --keyserver hkp://keyserver.ubuntu.com --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

2. 开始安装

\curl -sSL https://get.rvm.io | bash -s stable

3. 如果出现下图 表示成功了（需要你退出当前shell，再此登录；如果你有钱，也可以给该开发团队捐赠）

[root@node1 ~]# \curl -sSL https://get.rvm.io | bash -s stable

Creating group 'rvm'
Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
  * Please do NOT forget to add your users to the rvm group.
     The installer no longer auto-adds root or users to the rvm group. Admins must do this.
     Also, please note that group memberships are ONLY evaluated at login time.
     This means that users must log out then back in before group membership takes effect!
Thanks for installing RVM 🙏

4. 使用rvm -v验证一下，得到下图（表示成功安装了rvm）

[root@node1 ~]# rvm -v
rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]
[root@node1 ~]#

5. 开始安装ruby（现在新版本的ruby3.0会自动安装gem）

6. 验证ruby3.0和gem是否安装，同时按照Jekyll官网的要求，验证其他三个组件

ruby -v 和gem -v gcc -v g++ -v make -v 如果这三个命令没有输出显示版本号，证明当前系统未包含，最好还是安装

7. 鸡动人心的时刻，安装Jekyll

gem install bundler jekyll bundler是什么？那是因为官网推荐最好安装bundle
