本文跟大家分享的是在CentOS 7下配置Ruby语言开发环境的方法教程，分享出来供大家参考学习，下面来看看详细的介绍：
安装Ruby 2.2
CentOS7存储库中的Ruby版本为2.0，但如果需要，可以使用RPM软件包安装2.2
1、添加CentOS SCLo软件集合存储库
[root@linuxprobe ~]# yum -y install centos-release-scl-rh centos-release-scl # set [priority=10] [root@linuxprobe ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo [root@linuxprobe ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo # for another way, change to [enabled=0] and use it only when needed [root@linuxprobe ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo [root@linuxprobe ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo # if [enabled=0], input a command to use the repository [root@linuxprobe ~]# yum --enablerepo=centos-sclo-rh install [Package] [root@linuxprobe ~]# yum --enablerepo=centos-sclo-sclo install [Package] # 安装ruby yum --enablerepo=centos-sclo-rh -y install rh-ruby22
2、软件集合的软件包安装在/opt目录下， 要使用它，需要加载环境变量，如下所示:
# 加载环境变量 [root@linuxprobe ~]# scl enable rh-ruby22 bash [root@linuxprobe ~]# ruby -v ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux] [root@linuxprobe ~]# which ruby /opt/rh/rh-ruby22/root/usr/bin/ruby
3、设置登录时自动启用Ruby 2.2，按如下所示进行配置：
[root@linuxprobe ~]# vim /etc/profile.d/rh-ruby22.sh #!/bin/bash source /opt/rh/rh-ruby22/enable export X_SCLS="`scl enable rh-ruby22 'echo $X_SCLS'`" export PATH=$PATH:/opt/rh/rh-ruby22/root/usr/local/bin
安装Ruby 2.3
# 安装ruby yum --enablerepo=centos-sclo-rh -y install rh-ruby23
1、软件集合的软件包安装在/opt目录下， 要使用它，需要加载环境变量，如下所示:
# 加载环境变量 [root@linuxprobe ~]# scl enable rh-ruby23 bash [root@linuxprobe ~]# ruby -v ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux] [root@linuxprobe ~]# which ruby /opt/rh/rh-ruby22/root/usr/bin/ruby
2、设置登录时自动启用Ruby 2.3，按如下所示进行配置：
[root@linuxprobe ~]# vim /etc/profile.d/rh-ruby23.sh #!/bin/bash source /opt/rh/rh-ruby23/enable export X_SCLS="`scl enable rh-ruby23 'echo $X_SCLS'`" export PATH=$PATH:/opt/rh/rh-ruby23/root/usr/local/bin
安装Ruby on Rails 4来构建Ruby Framework环境
1、添加EPEL软件存储库
[root@linuxprobe ~]# yum -y install epel-release # set [priority=5] [root@linuxprobe ~]# sed -i -e "s/\]$/\]\npriority=5/g" /etc/yum.repos.d/epel.repo # for another way, change to [enabled=0] and use it only when needed [root@linuxprobe ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/epel.repo # if [enabled=0], input a command to use the repository [root@linuxprobe ~]# yum --enablerepo=epel install [Package]
Ruby on Rails 4
1、安装Ruby 2.2，参考上面
2、安装依赖包（epel+SCLo）
[root@linuxprobe ~]# yum --enablerepo=epel,centos-sclo-rh -y install rh-ruby22-ruby-devel nodejs libuv gcc make libxml2 libxml2-devel mariadb-devel zlib-devel libxslt-devel
安装Rails 4
[root@linuxprobe ~]# gem install bundler [root@linuxprobe ~]# gem install nokogiri -- --use-system-libraries [root@linuxprobe ~]# gem install rails --version="~>4.0" --no-ri --no-rdoc [root@linuxprobe ~]# /opt/rh/rh-ruby22/root/usr/local/bin/rails -v Rails 4.2.8
Ruby on Rails 5
1、安装Ruby 2.3，参考上面
2、安装依赖包（epel+SCLo）
[root@linuxprobe ~]# yum --enablerepo=epel,centos-sclo-rh -y install rh-ruby23-ruby-devel nodejs libuv gcc make libxml2 libxml2-devel mariadb-devel zlib-devel libxslt-devel
安装Rails 5
[root@linuxprobe ~]# gem install bundler [root@linuxprobe ~]# gem install nokogiri -- --use-system-libraries [root@linuxprobe ~]# gem install rails --no-ri --no-rdoc [root@linuxprobe ~]# rails -v Rails 5.0.2
创建一个示例应用程序，并确保其正常工作
1、需要安装MariaDB服务
[root@linuxprobe ~]# yum -y install mariadb-server [root@linuxprobe ~]# vi /etc/my.cnf # add follows within [mysqld] section [mysqld] character-set-server=utf8 [root@linuxprobe ~]# systemctl start mariadb [root@linuxprobe ~]# systemctl enable mariadb ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'
2、初始化MariaDB
[root@linuxprobe ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. # set root password Set root password"htmlcode">[root@linuxprobe ~]# gem install mysql2 --no-ri --no-rdoc -- --with-mysql-config=/usr/bin/mysql_config [root@linuxprobe ~]# rails new SampleApp -d mysql [root@linuxprobe ~]# cd SampleApp [root@linuxprobe SampleApp]# vi config/database.yml default: &default adapter: mysql2 encoding: utf8 pool: 5 username: root password: password # MariaDB password socket: /var/lib/mysql/mysql.sock # create test application [root@dlp SampleApp]# rails db:create Created database 'SampleApp_development' Created database 'SampleApp_test' [root@dlp SampleApp]# rails generate scaffold testapp name:string title:string body:text [root@dlp SampleApp]# rails db:migrate [root@dlp SampleApp]# rails server --binding=0.0.0.0 => Booting Puma => Rails 5.0.2 application starting in development on http://0.0.0.0:3000 => Run `rails server -h` for more startup options Puma starting in single mode... * Version 3.8.2 (ruby 2.3.1-p112), codename: Sassy Salamander * Min threads: 5, max threads: 5 * Environment: development * Listening on tcp://0.0.0.0:3000 Use Ctrl-C to stop4、客户端访问http://10.1.1.53:3000/
