复制代码
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
make clean
make distclean
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
make clean
make distclean
cd http://www.cnblogs.com/
3] mhash库
复制代码
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../
4］mcrypt库
注意：因为该库和libmcrypt有依赖性，所以在安装前必须知道libmcrypt，否则的话会出现：
错误
复制代码
checking for libmcrypt – version >= 2.5.0…
*** ‘libmcrypt-config –version’ returned 2.4.0, but LIBMCRYPT (2.5.8)
*** was found! If libmcrypt-config was correct, then it is best
*** to remove the old version of LIBMCRYPT. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If libmcrypt-config was wrong, set the environment variable LIBMCRYPT_CONFIG
*** to point to the correct copy of libmcrypt-config, and remove the file config.cache
*** before re-running configure
configure: error: *** libmcrypt was not found
是因为path的问题，所以执行：
复制代码
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
然后再安装：
复制代码
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../
二、安装mysql
复制代码
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql xxx
unzip mysql-5.1.33.zip
cd mysql-5.1.33/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables
--with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase
make
make install
make clean
make distclean
chmod +w /usr/local/webserver/mysql
chown -R xxx:mysql /usr/local/webserver/mysql
