centos7 Ruby环境变量配置

ruby安装参考博客:https://blog.csdn.net/yelllowcong/article/details/78362370 (Redis之集群redis-trib.rb环境的搭建-yellowcong)

vi /etc/profile 修改环境变量,添加红色部分:

for i in /etc/profile.d/*.sh /etc/profile.d/sh.local ; do
    if [ -r "$i" ]; then
        if [ "${-#*i}" != "$-" ]; then
            . "$i"
        else
            . "$i" >/dev/null
        fi
    fi
done

export RUBY_BIN=/usr/local/ruby-2.4.2/bin
export PATH=$PATH:$RUBY_BIN

source /etc/profile 重新生效环境变量
