How to Install Ruby2.3 on centos7
yum
yum install centos-release-scl-rh -y yum install rh-ruby27 -y scl enable rh-ruby27 bash ruby -v If you'd like to enable Ruby 2.7 automatically at login time, configure like follows. [root@dlp ~]# vi /etc/profile.d/rh-ruby27.sh # create new source /opt/rh/rh-ruby27/enable export X_SCLS="`scl enable rh-ruby27 'echo $X_SCLS'`"
rvm
#yum install ruby 高版本 # on java02 yum -y install curl #gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3 gpg2 --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB curl -L get.rvm.io | bash -s stable 4、查找配置文件 find / -name rvm.sh 5、配置文件生效 由上面的find 来决定 source /etc/profile.d/rvm.sh 6、下载rvm依赖 rvm requirements 7、查看rvm库ruby版本 rvm list known 8、安装ruby指定版本 直接执行 上面两个可选 rvm install ruby-2.3.8 #me rvm install ruby-2.4.1 好像这样默认就是2.3.8了 9、使用ruby版本默认 rvm use 2.3.8 default #rvm use 2.4.1 default rvm use 2.3.3 --default 10、gem install redis test redis-trib.rb #ok就表示成功了
