但是git是安装了的：

[root@localhost git]# git --version
git version 2.7.0
go也安装了的：

[root@localhost git]# go version
go version go1.5.3 linux/amd64
环境变量也配置了，但是好像还是无效的样子：

[root@localhost ~]# whereis git
git: /usr/local/bin/git /usr/local/git

[root@localhost ~]# vim /etc/profile

export GIT_HOME=/usr/local/bin/git
export PATH=$GIT_HOME:$GOROOT/bin:$PATH:$MAVEN_HOME/bin
