Subversion1.8之后，http资源类型支持库，apache从该版本之后，舍弃了neon。Subversion 1.8中http客户端基于neon已经被移除，改用self。如果要支持http方式需要在安装svn前安装serf，安装serf推荐用serf-1.2.1，安装是./configure；由于google官网下载比较麻烦，所有我这里分享给大家。好运！

源码安装svn serf_v1.2.1：

Linux下编译Serf_v1.2.1源码时，提示以下错误，有知道解决方法的朋友吗，麻烦共享下，谢谢！

/svn_setup/lib/libssl.a(s23_clnt.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
/svn_setup/lib/libssl.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libserf-1.la] Error 1

解决方案：出现此错误是在ubuntu环境中源码编译Svn时，安装serf_1.2.1出现的，

重新编译openssl时，添加上 -fPIC,--enable-share参数即可解决上述错误

serf-1.3.0安装是用scons（yum -y install scons）方式，安装serf-1.3.0后安装可能会报误，Google没找到解决方法，如下报错

checking for serf-2 library... no checking for serf-1 library... no checking was serf enabled... no An appropriate version of serf could not be found, so libsvn_ra_serf will not be built. If you want to build libsvn_ra_serf, please install serf 1.2.1 or newer. configure: error: Serf was explicitly enabled but an appropriate version was not found.

安装步骤：

本文只基于《LAMP一键安装包》之后进行
1. 安装apr、apr-unit

cd /root/lamp/source #wget #LAMP中已经下载 #wget tar xzf apr-1.4.8.tar.gz cd apr-1.4.8 ./configure --prefix=/usr/local/apache make && make install cd ../ tar xzf apr-util-1.5.2.tar.gz cd apr-util-1.5.2 ./configure --prefix=/usr/local/apache make && make install cd ../

  2. 安装serf-1.2.1

yum -y install expat-devel wget #serf-1.2.1.zip是win版有问题 tar xjf serf-1.2.1.tar.bz2 cd serf-1.2.1 ./configure --prefix=/usr/local/serf --with-apr=/usr/local/apache --with-apr-util=/usr/local/apache make && make install cd ..

 3. 安装svn

tar xzf subversion-1.8.1.tar.gz cd subversion-1.8.1 ./get-deps.sh ./configure --prefix=/usr/local/subversion --with-apxs=/usr/local/apache/bin/apxs --with-apr=/usr/local/apache --with-apr-util=/usr/local/apache --with-zlib --with-openssl --enable-maintainer-mode --with-serf=/usr/local/serf --enable-mod-activation make && make install cd ..

 4. 检查是否安装成功
安装成功会在/usr/local/apache/conf/httpd.conf自己加入下面2行

LoadModule dav_svn_module /usr/local/subversion/libexec/mod_dav_svn.so LoadModule authz_svn_module /usr/local/subversion/libexec/mod_authz_svn.so

检查svn是否支持http方式：
