centos7.x搭建svn server

q989

简介

Subversion(SVN) 是一个开源的版本控制系統, 也就是说 Subversion 管理着随时间改变的数据。这些数据放置在一个中央资料档案库(repository) 中。这个档案库很像一个普通的文件服务器, 不过它会记住每一次文件的变动。这样你就可以把档案恢复到旧的版本, 或是浏览文件的变动历史。

　　

SVN 的一些概念

repository（源代码库）:源代码统一存放的地方

Checkout（提取）:当你手上没有源代码的时候，你需要从repository checkout一份

Commit（提交）:当你已经修改了代码，你就需要Commit到repository

Update (更新):当你已经Checkout了一份源代码，Update一下你就可以和Repository 上的源代码同步，你手上的代码就会有最新的变更

日常开发过程其实就是这样的（假设你已经Checkout并且已经工作了几天）：Update(获得最新的代码) —>作出自己的修改并调试成功 —> Commit(大家就可以看到你的修改了) 。

如果两个程序员同时修改了同一个文件呢, SVN可以合并这两个程序员的改动，实际上SVN管理源代码是以行为单位的，就是说两个程序员只要不是修改了同一行程序，SVN都会自动合并两种修改。

如果是同一行，SVN会提示文件Confict, 冲突，需要手动确认。

　　

　　subversion目录说明：
　　db目录：就是所有版本控制的数据存放文件。
　　hooks目录：放置hook脚本文件的目录。
　　locks目录：用来放置subversion见艰苦锁定数据的目录，用来追踪存取文件库的客户端。
　　format文件：是一个文本文件，里面只放了一个整数，表示当前文件库配置的版本号。
　　conf目录：是这个仓库的配置文件（仓库的用户访问账号、权限等）。
　　进入conf目录（该svn版本库配置文件）cd conf/
　　authz 文件是权限控制文件
　　passwd 是帐号密码文件
　　svnserve.conf SVN服务配置文件
#添加svn账号，并且禁止登陆
useradd -M -s /sbin/nologin svn[root@localhost ~]# yum install subversion -y

authz  passwd  svnserve.conf
[root@localhost conf]# vim passwd
### This file is an example password file for svnserve.
### Its format is similar to that of svnserve.conf. As shown in the
### example below it contains one section labelled [users].
### The name and password for each user follow, one account per line.
[users]
# harry = harryssecret
# sally = sallyssecret
#添加admin用户
admin = 123456                             
[root@localhost conf]# vim authz
### This file is an example authorization file for svnserve.
### Its format is identical to that of mod_authz_svn authorization
### files.
### As shown below each section defines authorizations for the path and
### (optional) repository specified by the section name.
### The authorizations follow. An authorization line can refer to:
###  - a single user,
###  - a group of users defined in a special [groups] section,
###  - an alias defined in a special [aliases] section,
###  - all authenticated users, using the '$authenticated' token,
###  - only anonymous users, using the '$anonymous' token,
###  - anyone, using the '*' wildcard.
###
### A match can be inverted by prefixing the rule with '~'. Rules can
### grant read ('r') access, read-write ('rw') access, or no access
### ('').
[aliases]
# joe = /C=XZ/ST=Dessert/L=Snake City/O=Snake Oil, Ltd./OU=Research Institute/CN=Joe Average
[groups]
# harry_and_sally = harry,sally
# harry_sally_and_joe = harry,sally,&joe
# [/foo/bar]
# harry = rw
# &joe = r
# * =
# [repository:/baz/fuz]
# @harry_and_sally = rw
# * = r

[root@localhost conf]# cat svnserve.conf
### This file controls the configuration of the svnserve daemon, if you
### use it to allow access to this repository.  (If you only allow
### access through http: and/or file: URLs, then this file is
### irrelevant.)
### Visit http://subversion.apache.org/ for more information.
[general]
### The anon-access and auth-access options control access to the
### repository for unauthenticated (a.k.a. anonymous) users and
### authenticated users, respectively.
### Valid values are "write", "read", and "none".
### Setting the value to "none" prohibits both reading and writing;
### "read" allows read-only access, and "write" allows complete
### read/write access to the repository.
### The sample settings below are the defaults and specify that anonymous
### users have read-only access to the repository, while authenticated
### users have read and write access to the repository.
#匿名用户可读
# anon-access = read
anon-access = none
# auth-access = write
### The password-db option controls the location of the password
### database file.  Unless you specify a path starting with a /,
### the file's location is relative to the directory containing
### this configuration file.
### If SASL is enabled (see below), this file will NOT be used.
### Uncomment the line below to use the default password file.
#使用哪个文件作为账号文件
password-db = passwd
### The authz-db option controls the location of the authorization
### rules for path-based access control.  Unless you specify a path
### starting with a /, the file's location is relative to the the
### directory containing this file.  If you don't specify an
### authz-db, no path-based access control is done.
### Uncomment the line below to use the default authorization file.
#使用哪个文件作为权限文件
authz-db = authz
### This option specifies the authentication realm of the repository.
### If two repositories have the same authentication realm, they should
### have the same password database, and vice versa.  The default realm
### is repository's uuid.
#认证空间名，版本库所在目录
realm = /var/svn/svnrepos
### The force-username-case option causes svnserve to case-normalize
### usernames before comparing them against the authorization rules in the
### authz-db file configured above.  Valid values are "upper" (to upper-
### case the usernames), "lower" (to lowercase the usernames), and
### "none" (to compare usernames as-is without case conversion, which
### is the default behavior).
# force-username-case = none
[sasl]
### This option specifies whether you want to use the Cyrus SASL
### library for authentication. Default is false.
### This section will be ignored if svnserve is not built with Cyrus
### SASL support; to check, run 'svnserve --version' and look for a line
### reading 'Cyrus SASL authentication is available.'
# use-sasl = true
### These options specify the desired strength of the security layer
### that you want SASL to provide. 0 means no encryption, 1 means
### integrity-checking only, values larger than 1 are correlated
### to the effective key length for encryption (e.g. 128 means 128-bit
### encryption). The values below are the defaults.
# min-encryption = 0
# max-encryption = 256
