作者 在CentOs, 微服务 标签 ,

查看系统版本

lsb_release -a
uname
rpm -q redhat-release
cat /proc/version

升级内核

vi /etc/sysconfig/network-scripts/ifcfg-eth0 配制DNS
yum update nss
rpm –import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 导入KEY
rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm 安装ELRepo
yum –enablerepo=elrepo-kernel install kernel-lt –y 安装内核
vi /etc/grub.conf # 改为default=0 修改引导文件,将默认引导改为0
reboot 启完成后查看内核版本

安装docker

yum install docker-io
提示错误：No package docker-io available，则运行
yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum install epel-release
yum -y install https://get.docker.com/rpm/1.7.1/centos-6/RPMS/x86_64/docker-engine-1.7.1-1.el6.x86_64.rpm
service docker start
查看已安装的包：
yum list installed | grep docker
删除软件包：
yum -y remove docker-io.x86_64
删除镜像/容器：
rm -rf /var/lib/docker

Error

docker 安装之后，通过命令查看docker相关信息时，可能会出现错误：Get http:///var/run/docker.sock/v1.19/version: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?
服务无法正常停止或重启，可能就是系统环境出现了问题，
You may have to enable the public_ol6_latest repo in order to get this package.
sudo yum-config-manager –enable public_ol6_latest
And then install the package:
sudo yum install device-mapper-event-libs

gitlab安装配置使用

作者 在CentOs, Mac, Ubuntu, 其它工具 标签

Docker install

gitlab-ce为稳定版本，后面不填写版本则默认pull最新latest版本

$ docker pull gitlab/gitlab-ce
docker pull twang2218/gitlab-ce-zh 汉化版

sudo docker run  --name gitlab \
  -itd \
  -p 443:443 -p 80:80 -p 222:22 \
  --privileged=true \
  -v /Users/sweet/gitlab/config:/etc/gitlab:Z \
  -v /Users/sweet/gitlab/logs:/var/log/gitlab:Z \
  -v /Users/sweet/gitlab/data:/var/opt/gitlab:Z \
  gitlab/gitlab-ce

 --restart always \

sudo docker exec -it gitlab /bin/bash
You can also just edit /etc/gitlab/gitlab.rb:
sudo docker exec -it gitlab editor /etc/gitlab/gitlab.rb

# gitlab.rb文件内容默认全是注释
$ vim /home/gitlab/config/gitlab.rb

# 配置http协议所使用的访问地址,不加端口号默认为80
external_url 'http://192.168.199.231'

# 配置ssh协议所使用的访问地址和端口
gitlab_rails['gitlab_ssh_host'] = '192.168.199.231'
gitlab_rails['gitlab_shell_ssh_port'] = 222 # 此端口是run时22端口映射的222端口
:wq #保存配置文件并退出
# 重启gitlab容器
$ docker restart gitlab

====================
sudo apt-get install -y curl openssh-server ca-certificates 依赖
sudo apt-get install -y postfix 发送邮件
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash 下载
sudo EXTERNAL_URL=“http://gitlab.example.com”apt-get install gitlab-ee 安装
首次访问时，您将被重定向到密码重置屏幕。提供初始管理员帐户的密码，您将被重定向回登录屏幕。使用默认帐户的用户名root登录

1）进入文件gitlab.rb，修改EXTERNAL_URL地址和端口号

sudo vim /etc/gir/gitlab.rb

sudo vim /etc/gitlab/gitlab.rb

EXTERNAL_URL 修改为本机服务地ip地址，并分配端口号（例如：4567）。

2）重新配置 sudo gitlab-ctl reconfigure

3）开启服务 service sshd start service postfix start

4）查看运行状态： sudo gitlab-ctl status 如果run正常，则成功
Git global setup

git config –global user.name “Administrator”
git config –global user.email “admin@example.com”

Create a new repository

git clone http://e132f243a5fe/shanpai/config.git

git init
git remote add origin http://e132f243a5fe/shanpai/config.git
git add .
git commit -m “Initial commit”
git push -u origin master

Push an existing Git repository

cd existing_repo
git remote rename origin old-origin
