版本管理：Subversion Edge：仓库创建与使用
SVN可以通过svn或者http协议来进行svn co操作下拉代码，后者需要配置apache等成功设定才可，这篇文章通过在Subversion Edge中创建仓库，然后在客户端进行co和ci操作进行功能的说明。
环境准备
可以参看如下内容进行目前最新版的5.2.4的Subversion Edge的环境准备。
- 安装说明：https://liumiaocn.blog.csdn.net/article/details/107463097
- 一键安装：https://liumiaocn.blog.csdn.net/article/details/108174169
环境说明：本文使用环境为在Virtual Box上创建的CentOS 7.6，IP为192.168.163.121，与主机进行端口映射，比如3343，主机通过localhost的3343直接可以访问csvn的Web服务。80端口的服务被映射为9999
登录并创建仓库
使用如下信息进行登录
| 项目 | 详细 |
|---|---|
| 登录URL | http://localhost:3343/csvn |
| 用户名 | admin |
| 用户密码 | admin |
点击Repository菜单进行进一步操作
点击Create按钮进行仓库的创建
输入仓库的名称，此处选择标准方式，会缺省创建trunk/branches/tags，这是svn和git在分支操作上明显的不同之处。
点击Create即可看到已经成功创建了名为demo-repo的svn仓库了。
然后点击左侧菜单栏中Repository list的链接，可以看到包含svn co访问地址的如下详细信息
修改hostname
修改hostname为所在机器的IP并保存，缺省会通过80端口进行http协议服务的访问。
客户端使用
Edge所在机器安装客户端并验证
- Subversion Edge所在机器安装客户端
执行命令：yum install svn -y
[root@liumiaocn ~]# yum install svn -y
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

Complete!
[root@liumiaocn ~]#

可以通过http协议进行访问，通过浏览器可以进行查看，登录时输入相应具有权限的用户名和密码，此处输入admin/admin
可以看到创建的trunk/branches/tags
进入trunk，可以看到刚刚提交的文件信息
常见错误与对应
Unable to connect to a repository
- 现象： Connection reset by peer
liumiaocn:edge liumiao$ svn co http://127.0.0.1:9999/svn/demo-repo demo-repo --username=admin
svn: E170013: Unable to connect to a repository at URL 'http://127.0.0.1:9999/svn/demo-repo'
svn: E000054: Error running context: Connection reset by peer
liumiaocn:edge liumiao$
- 原因：本文中出现的原因是因为firewalld没有打开端口
[root@liumiaocn ~]# firewall-cmd --list-ports
3343/tcp
[root@liumiaocn ~]#
- 对应方法：在firewall中打开80端口并进行reload操作
[root@liumiaocn ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@liumiaocn ~]# firewall-cmd --reload
success
[root@liumiaocn ~]# firewall-cmd --list-ports
3343/tcp 80/tcp
[root@liumiaocn ~]#
