MySQL 镜像的下载、启动容器

从默认的仓库拉取mysql镜像：docker pull mysql
查看本地有哪些镜像：docker images
运行mysql镜像生成名字叫做mysql2的容器，映射主机端口是13306，root密码是123456 ： docker run
查看本地创建了哪些容器 docker ps
交互方式进入mysql2容器的shell环境，创建一个数据库testdb docker exec

[root@localhost ~]# docker pull mysql
[root@localhost ~]# docker images

Gogs 的配置和使用

打开chrome 浏览器，输入网址：http://192.168.1.161:10080/
第一次访问Gogs，浏览器进入安装页面，如图所示填写字段：

[图片上传失败...(image-f6d30a-1522666749864)]

[图片上传失败...(image-e64808-1522666749864)]
编辑 Gogs 配置文件（vi /var/gogs/gogs/conf/app.ini）
修改 ROOT_URL = http://192.168.1.161:10080/

......
[server]
DOMAIN       = 192.168.1.161
HTTP_PORT    = 3000
ROOT_URL     = http://192.168.1.161:10080/
DISABLE_SSH  = false
SSH_PORT     = 10022
OFFLINE_MODE = false
......

问题：为什么可以修改 Host 的 /var/gogs/ 目录的文件，就可以改变容器里的配置文件？
答案：因为启动容器的时候，我们使用 -v /var/gogs:/data 把 Host 里的目录 /var/gogs 挂载到容器的/data/目录

一款极易搭建的自助 Git 服务。

环境

centos7：golang+mysqldb+git

安装配置环境

yum install mysql-community-server  go  git  -y

配置防火墙 selinux

安装配置数据库

这个mysql不允许简单的密码，所以第三条语句我未执行，后面安装时候直接用root作为数据库的用户。gogs推荐使用InnoDB引擎。创建库时候选择utf8.

systemctl start mysqld ;systemctl enable mysqld
//开启数据库服务

cat /var/log/mysqld.log | grep password
//获得mysql root密码

mysql_secure_installation
//初始化数据库 使用上一步获得密码

mysqld -u root -p
//登录mysql

SET GLOBAL storage_engine = ‘InnoDB‘;
CREATE DATABASE gogs CHARACTER SET utf8 COLLATE utf8_bin;
GRANT ALL PRIVILEGES ON gogs.* TO ‘root’@‘localhostIDENTIFIED BY ‘itadmin’;
FLUSH PRIVILEGES;
QUIT；
//SQL语句

安装配置gogs

wget https://dl.gogs.io/0.11.4/linux_amd64.tar.gz
//下载软件包

tar  -zxf  linux_amd64.tar.gz;   mv gogs    /gogs
//解压

useradd git
chown -R  git:git   /gogs
mkdir /gogs-repositories
chown  -R  git:git   /gogs-repositories
//添加git用户 

su git
/gogs/gogs web &
//启动gogs

最下方配置选项建议点一点做详细配置，如果添加内置SSH避开系统上的22端口，管理员账号不允许admin 避开吧
