1 、安装操作系统 a、升级操作系统和安装wget sudo yum -y update  sudo yum -y install wget 查看版本信息 lsb_release -a 报错 -bash: lsb_release: command not found 解决办法 yum install redhat-lsb -y  centos 6.8 安装gitlab 和 centos 6.5 安装gitlab 一样 b、增加EPEL安装源 sudo wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 https://www.fedoraproject.org/static/0608B895.txt sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 检验下是否安装成功 sudo rpm -qa gpg*  安装epel-release-6-8.noarch包 sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm c、查看仓库源 yum repolist  如果此列表中没有epel和PUIAS_6_computational，请执行以下命令 yum-config-manager --enable epel --enable 报错 bash: yum-config-manager: command not found 解决方法：yum -y install yum-utils 三，安装git 默认centos的git版本是1.7.10，所以要先删除，然后再下载源码安装 yum remove git -y yum install zlib-devel perl-CPAN gettext curl-devel expat-devel gettext-devel openssl-devel mkdir /tmp/git && cd /tmp/git curl --progress https://www.kernel.org/pub/software/scm/git/git-2.1.3.tar.gz | tar xz cd git-2.1.3/ && ./configure && make && make prefix=/usr/local install 完成后验证 which git /usr/local/bin/git git --version git version 2.1.3 如果安装存在问题 2.源码安装Git 参见：http://www.cnblogs.com/jim-hwg/p/4748008.html 3.源码安装Ruby 参见：http://www.cnblogs.com/jim-hwg/p/4746977.html 4.源码安装MySQL 参见：http://www.cnblogs.com/jim-hwg/p/4747165.html 安装gitlab sudo yum install curl openssh-server openssh-clients postfix cronie sudo service postfix start sudo chkconfig postfix on sudo lokkit -s http -s ssh curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash sudo yum install gitlab-ce
