1.3 环境初始化

echo "设置时钟同步"
yum install -y chrony
systemctl start chronyd.service
systemctl enable chronyd.service

echo "关闭防火墙"
systemctl stop firewalld
systemctl disable firewalld

echo "关闭 selinux"
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
getenforce

echo "优化 ssh 登录速度"
sed -i 's/#UseDNS yes/UseDNS no/g' /etc/ssh/sshd_config
systemctl restart sshd

echo "安装基础软件 lrzsz, epel-release"
yum install epel-release lrzsz -y

1.4 升级内核

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
# 安装ELRepo
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
# 载入elrepo-kernel元数据
yum --disablerepo=\* --enablerepo=elrepo-kernel repolist
# 查看可用的rpm包
yum --disablerepo=\* --enablerepo=elrepo-kernel list kernel*
# 安装长期支持版本的kernel
yum --disablerepo=\* --enablerepo=elrepo-kernel install -y kernel-lt.x86_64
# 删除旧版本工具包
yum remove kernel-tools-libs.x86_64 kernel-tools.x86_64 -y
# 安装新版本工具包
yum --disablerepo=\* --enablerepo=elrepo-kernel install -y kernel-lt-tools.x86_64

#查看默认启动顺序
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg  

#默认启动的顺序是从0开始，新内核是从头插入（目前位置在0，而4.4.4的是在1），所以需要选择0。
grub2-set-default 0

reboot

当前最新稳定内核版本 CentOS Linux (5.4.180-1.el7.elrepo.x86_64) 7 (Core)

1.5 安装 docker

参考：Get Docker| Docker Documentation 或者

echo "
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1" >> /etc/sysctl.conf
sysctl -p

curl https://releases.rancher.com/install-docker/19.03.sh | sh
systemctl enable docker

设置国内源

vi /etc/docker/daemon.json
{
    "registry-mirrors": ["https://hccwwfjl.mirror.aliyuncs.com"]
}
systemctl restart docker

其他源：http://hub-mirror.c.163.com，建议用这个 163 的

1.6 安装 docker machine

参考：Testing Environment | GitLab

$ curl -L https://github.com/docker/machine/releases/download/v0.16.2/docker-machine-`uname -s`-`uname -m` >/usr/local/bin/docker-machine && \
  chmod +x /usr/local/bin/docker-machine

$ docker-machine version
docker-machine version 0.16.2, build bd45ab13

2. 安装极狐gitlab

参考官方文档：Testing Environment | GitLab

2.1 获取可用的极狐gitlab镜像tags

$ curl https://version.gitlab.cn/api/v1/versions

2.2 设置环境变量

export SSH_PORT=2222
export HTTP_PORT=8888
export VERSION=15.1.2
export ENV_NAME=gitlab-test-env
export CONTAINER_NAME=gitlab-test-14.7.3

2.3 创建 docker host

docker-machine create \
--virtualbox-cpu-count -1 \
--virtualbox-memory 4096 \
--virtualbox-disk-size 30000 \
--driver virtualbox $ENV_NAME

会出现以下报错

Creating CA: /root/.docker/machine/certs/ca.pem
Creating client certificate: /root/.docker/machine/certs/cert.pem
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"

原因是未安装 VirtualBox，解决方法如下

Linux_Downloads – Oracle VM VirtualBox

wget https://download.virtualbox.org/virtualbox/6.1.32/VirtualBox-6.1-6.1.32_149290_el7-1.x86_64.rpm
yum install -y VirtualBox-6.1-6.1.32_149290_el7-1.x86_64.rpm

必须使用 yum 安装 rpm 包，以便解决依赖

再次运行 docker-machine 创建命令，出现以下报错：

Running pre-create checks...
Error with pre-create check: "We support Virtualbox starting with version 5. Your VirtualBox install is \"WARNING: The vboxdrv kernel module is not loaded. Either there is no module\\n         available for the current kernel (5.4.180-1.el7.elrepo.x86_64) or it failed to\\n         load.

按照提示执行命令 /sbin/vboxconfig

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.  If your system is using EFI Secure Boot you may need to sign the
kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load
them. Please see your Linux system's documentation for more information.

根据提示执行

yum install -y gcc make perl

# 会提示找不到 kernel-devel-5.4.180-1.el7.elrepo.x86_64
yum install -y kernel-devel kernel-devel-5.4.180-1.el7.elrepo.x86_64

原因是前面我们升级了内核到 5.4，内核太新了，重新使用默认 3.10 内核

#查看默认启动顺序

reboot

重启后执行 /sbin/vboxconfig

根据提示执行

yum install -y kernel-devel kernel-devel-3.10.0-1160.el7.x86_64

再执行 /sbin/vboxconfig

$ /sbin/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.

成功编译进内核

再次执行 docker-machine，还是报错：

Running pre-create checks...
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

原因是 vm 未开启硬件虚拟化，关闭虚拟机，开启即可

图片此处省略

• 勾选 虚拟化 Intel VT-X/EPT 或 AMD-V/RVI(V)

重启后再次运行 docker-machine，结果因为网络原因下载镜像失败

Running pre-create checks...

解决方法很简单，先在合适网络下下载 https://github.com/boot2docker/boot2docker/releases/download/v19.03.12/boot2docker.iso，然后把 boot2docker.iso 放到目录 /root/.docker/machine/cache/ 下即可

再次运行 docker-machine

VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp

解决方法如下：

1. docker-machine ls 的所有计算机
2. 用 docker-machine rm -y <machineName> 删除它们
3. 用 VBoxManage list hostonlyifs 查找所有 host-only 以太网适配器
4. 用 VBoxManage hostonlyif remove <networkName> 逐个删除它们
5. 创建 /etc/vbox 文件夹
6. 写入文件 echo "* 0.0.0.0/0 ::/0" > /etc/vbox/networks.conf

这种解决方法可能会导致启动 docker 机器时 Waiting for an IP...会花费多一点时间

再次创建 host，正常运行了

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env gitlab-test-env

$ docker-machine ls

2.4 连接到 docker host

eval "$(docker-machine env ${ENV_NAME})"

如果需要长期使用可以添加到配置文件：echo 'eval "$(docker-machine env gitlab-test-env)"' >> ~/.bash_profile

查看是否生效

2.5 创建极狐gitlab容器

export IP=$(docker-machine ip $ENV_NAME)

docker run -d \
--env GITLAB_OMNIBUS_CONFIG="external_url 'http://$IP:$HTTP_PORT'; gitlab_rails['gitlab_shell_ssh_port'] = $SSH_PORT;" \
--hostname $IP \
-p $HTTP_PORT:$HTTP_PORT -p $SSH_PORT:22 \
--name $CONTAINER_NAME \
registry.gitlab.cn/omnibus/gitlab-jh:$VERSION

$ docker ps
CONTAINER ID        IMAGE                          COMMAND             CREATED             STATUS                                 PORTS                                                           NAMES

2.6 访问极狐gitlab

首先获取 docker host 虚拟机 ip

$ echo $IP
192.168.99.100

# 获取 root 账号初始密码
docker exec ${CONTAINER_NAME} cat /etc/gitlab/initial_root_password

访问 http://192.168.99.100:8888 即可看到极狐gitlab页面
