SVN介紹

• SVN是個自由、開源的版本控制系統，絕大多數開源軟件都使用SVN作為代碼版本管理軟件。

• SVN的官方網站http://subversion.apache.org/。目前SVN在開源社區中非常流行的一款版本控制軟件，它是CVS的替代產物。

SVN服務端安裝

部署規劃

安裝部署

YUM安裝SVN

yum install httpd httpd-devel subversion mod_dav_svn mod_auth_mysql -y

創建相關目錄

創建svn數據目錄

mkdir -p /data/svndata/

新建ztjy倉庫

svnadmin create /data/svndata/ztjy
?
 
[root@localhost svn]$ ls -al  /data/svndata/ztjy       #查看創建的倉庫目錄 
total 24

• 倉庫目錄說明:

  hooks目錄：放置hook腳步文件的目錄
   
  ?
  locks目錄：用來放置subversion的db鎖文件和db_logs鎖文件的目錄，用來追蹤存取文件庫的客戶端
  ?
  format目錄：是一個文本文件，裏邊只放了一個整數，表示當前文件庫配置的版本號
  ?
  conf目錄：是這個倉庫配置文件（倉庫用戶訪問賬戶，權限）
  ?
  db目錄:倉庫數據目錄

修改相關配置文件

配置SVN服務的配置文件svnserver.conf

?
[root@localhost conf]# vim 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.tigris.org/ for more information.
[general]
### These options control access to the repository for unauthenticated
### and authenticated users.  Valid values are "write", "read",
### and "none".  The sample settings below are the defaults.
anon-access = read         ##註意前邊不要有空格，要頂齊
auth-access = write         ##註意前邊不要有空格，要頂齊
### 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.
password-db = passwd        ##註意前邊不要有空格，要頂齊
### 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.
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.
realm = ztjy   ##這個是提示信息
[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
?

配置訪問用戶及密碼

?
[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]
awk = abc123456   # 切記‘=‘兩邊的空格   密碼建議設置復雜密碼
sed = 123456
grep = 654321
?

配置新用戶的授權文件

?
[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]
[groups]
admin = awk,sed  #創建admin組，組成員為：awk,sed
user = grep     #  創建用戶組，用戶成員：grep
[ztjy:/]     #賦予根權限，為了便於管理和權限的控制，可以把權限細化到版本庫中相應的目錄
@admin = rw     ##授予admin組內用戶可讀可寫的權限
@user = r       ## 授予user組用戶只讀的權限
* = r           ##授予其他的用戶和用戶組只讀權限
?

書寫註意事項

• [/],表示根目錄及其一下的路徑，根目錄是svnserver啟動時指定好的，上述實例中我們指定 為:/data/svndata([/]=/data/svndata).[/]就是表示對全部版本設置的權限

• [ztjy:/],表示對版本庫ztjy設置權限；

• [ztjy:/svnadmin],表示對版本庫ztjy中的svnadmin項目設置權限；

• [ztjy:/svnadmin/second],表示對版本庫ztjy中的svnadmin項目的目錄設置權限；

• 權限的主體可以是用戶組，用戶或者，用戶組在前面要以@開頭，表示全部用戶

• 權限分為：r ,w, rw和null ,null空表示沒有任何權限。

• auhtz配置文件中的每個參數，開頭不能有空格，對於組要以@開頭，用戶不需要。

啟動svn服務

/usr/bin/svnserve -d -r /data/svndata/ --listen-port 9984 --log-file /data/logs/svn/svn.log --pid-file /data/logs/svn/svn.pid  &
