近日有需求，需要将原有SVN的数据迁移至Gitlab上，原SVN停用。
经过一番查找和测试，网上大部分方法差不多，但并不成功。
后查看了下Gitlab官方网站的操作方法，是挻简单，主要是使用了一个ruby的svn2git的工具来进行格式变换操作，可能是由于yum安装版本过低的原因，仍然不成功：
yum install svn git git-svn ruby
gem install svn2git
cd /opt
svn co svn://ipaddr/project
cd project/
svn log -q | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u > /home/users.txt
svn2git svn://ipaddr/project/ios --authors /home/users.txt --username administrator
git remote add origin [email protected]:<group>/<project>.git
git push --all origin
git push --tags origin
原方法操作是挻简单，先通过svn log找出所有提交过的用户，然后转换成gitlab的格式；然后通过svn2git工具来检出svn项目，并同时转换成git格式。但执行git2svn时却出现问题：
[root@localhost ios]# mkdir /opt/ios [root@localhost ios]# cd /opt/ios [root@localhost ios]# svn2git svn://10.10.0.68/zongsproject/ios --authors /home/users.txt --username administrator Initialized empty Git repository in /opt/ios/.git/ Using higher level of URL: svn://10.10.0.68/zongsproject/ios => svn://10.10.0.68/zongsproject command failed: git checkout -f master [root@localhost ios]# rm -rf .git/ [root@localhost ios]# svn2git svn://10.10.0.68/zongsproject/ios --authors /home/users.txt --rootistrunk --username administrator Initialized empty Git repository in /opt/ios/.git/ E: 'svn:/10.10.0.68/project/ios' is not a complete URL and a separate URL is not specified command failed: git svn init --prefix=svn/ --username='administrator' --no-metadata --trunk='svn://10.10.0.68/project/ios'
一直提示命令执行失败，且公司SVN上项目的结构与标准SVN结构不一致，经查看git2svn的使用说明，添加了参数后依然执行不成功，于是怀疑跟程序版本有关。
后所有程序均使用源码安装，git2svn命令可成功执行，这里记录下，过程还是有些曲折的，主要是安装perl模块SVN::Core时，由于其它依赖库不在系统默认搜索路径中导致：

SVN安装：
wget http://mirrors.hust.edu.cn/apache/subversion/subversion-1.10.3.tar.gz tar zxf subversion-1.10.3.tar.gz -C /usr/local/src/ cd /usr/local/src/subversion-1.10.3/ CFLAGS="-fPIC -O3" CC="gcc -std=gnu99" ./configure --enable-optimize --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr --with-serf=/usr/local --with-zlib=/usr/local/lib --with-sasl=/usr/local/sasl/ --with-lz4=internal make -j `nproc` && make install cd -
Git安装：
wget https://github.com/git/git/archive/v2.19.1.tar.gz -O git-2.19.1.tar.gz tar zxf git-2.19.1.tar.gz -C /usr/local/src/ cd /usr/local/src/git-2.19.1/ make configure CPPFLAGS=-I/usr/local/openssl/include LDFLAGS=-L/usr/local/openssl/lib CFLAGS="-fPIC -O3" ./configure --prefix=/usr/local --with-zlib=/usr/local --with-python=/usr/local/python3 --with-curl=/usr/local/curl --with-openssl=/usr/local/openssl make -j `nproc` && make install
PERL的SVN::Core，默认它自己下的svn包过旧，且会出现编译配置失败问题（因为上面大部分库是单独路径），故需手动安装下：
CFLAGS="-fPIC -O3 -std=gnu99" cpan SVN::Core .. error .. cd /root/.cpan/build/Alien-SVN-v1.8.11.0-0 mv src/subversion/ src/subversion2 cp -rfp /usr/local/src/subversion-1.10.3/ src/subversion cd src/subversion/ make distclean CFLAGS="-fPIC -O3 -std=gnu99" PERL=/usr/local/perl/bin/perl ./configure --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr --with-serf=/usr/local --with-zlib=/usr/local/lib --with-sasl=/usr/local/sasl/ --libdir=/usr/local/perl/lib/site_perl/5.28.0/x86_64-linux/Alien/SVN --prefix=/usr/local/perl --with-lz4=internal make -j 4 cd - ./Build ./Build install
svn2git安装:
gem install svn2git
然后再执行转换检出命令即可成功：
mkdir /opt/ios cd /opt/ios svn2git svn://10.10.0.68/project/ios --authors /home/users.txt --rootistrunk --username administrator
然后在gitlab中新建一个空项目：
在刚才的目录中执行连接并上传：
git remote add origin http://172.16.220.223/root/ios.git git push --all origin git push --tags origin
