《工具箱-SVN》SVN安装、备份、迁移教程

一、服务器搭建SVN

1.检查SVN是否存在

[root@hadoop_zxy ~]# svn -version
-bash: svn: command not found

2.安装SVN

[root@hadoop_zxy ~]# yum install subversion
Loaded plugins: fastestmirror, langpacks
Installed:
  subversion.x86_64 0:1.7.14-16.el7

Dependency Installed:
  gnutls.x86_64 0:3.3.29-9.el7_6        neon.x86_64 0:0.30.0-4.el7                    nettle.x86_64 0:2.7.1-9.el7_9
  pakchois.x86_64 0:0.4-10.el7          subversion-libs.x86_64 0:1.7.14-16.el7        trousers.x86_64 0:0.3.14-2.el7

Complete!

3.创建版本库

[root@hadoop_zxy apps]# mkdir /zxy/apps/svn
[root@hadoop_zxy apps]# ls
elasticsearch-6.5.3  jdk1.8.0_311  kafka_2.11-1.1.1  kibana-6.5.3  scala-2.11.8  svn  zookeeper-3.6.3
[root@hadoop_zxy apps]# cd svn

4.创建版本库存放文件地址

[root@hadoop_zxy svn]# svnadmin create /zxy/apps/svn/repositories

5.修改配置文件

5.1 vim authz

新增以下部分：

[/]

用户名= rw

[/] 表示控制的路径是全部，用户名自定义， rw 表示的权限 可读写

[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
#


[/]

用户名 = rw

~

5.2 vim passwd

新增以下部分：

用户名 = 密码

用户名和密码处自定义

[users]
# harry = harryssecret
# sally = sallyssecret
#
用户名 = 密码
~

5.3 vim svnserve.conf

释放并修改以下部分

anon-access = none
auth-access = write

password-db = passwd

authz-db = authz
realm = repositories

### 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.
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.

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.
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 = repositories
### 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

6.启动并查看SVN

[root@hadoop_zxy conf]# svnserve -d -r /zxy/apps/svn/

[root@hadoop_zxy conf]#  netstat -apn | grep 3690
tcp        0      0 0.0.0.0:3690            0.0.0.0:*               LISTEN      7757/svnserve

7.SVN Checkout

用于初次下载项目

8.SVN Update

用于更新项目内容

9.SVN Commit

用于提交项目更改内容

二、SVN-无法连接主机，目标计算机积极拒绝，无法连接

1.检查SVN进程

发现SVN进程已经关闭，想起来前几天重启了一下服务器，SVN服务器没有设置开机自启

[root@hadoop_zxy ~]# ps -ef | grep svn
root      3652  2079  0 11:31 pts/0    00:00:00 grep --color=auto svn

2.手动启动SVN

[root@hadoop_zxy ~]# svnserve -d -r/zxy/apps/svn
[root@hadoop_zxy ~]# ps -ef | grep svn
root      4690     1  0 11:33 ?        00:00:00 svnserve -d -r/zxy/apps/svn
root      4707  2079  0 11:33 pts/0    00:00:00 grep --color=auto svn
[root@hadoop_zxy ~]#

3.重新尝试使用SVN

注意：大家在重启服务器后，一定要记得查看SVN的进程

三、SVN备份、迁移

SVN需要备份，或者SVN服务器迁移，可以使用svnadmin的dump和load命令进行操作。

1.将源SVN版本库文件备份

svnadmin dump /zxy/apps/svn/old > dataproject

2.将备份文件发送到新的服务器

scp /zxy/apps/svn/dataproject root@ip:/zxy/apps/svn

3.在目标服务器的SVN中创建版本库存放文件地址

新创建的版本库文件地址，需要修改相关的配置文件，参考第一章即可

svnadmin create /zxy/apps/svn/new
svnadmin load /zxy/apps/svn/new < ./dataproject
