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；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- library... no
checking for serf- 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. 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 http://archive.apache.org/dist/apr/apr-1.4.8.tar.gz #LAMP中已经下载
#wget http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz
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 http://serf.googlecode.com/files/serf-1.2.1.tar.bz2 #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：
# svn --version
