apache:
问题：
安装apache的时候入到 error: mod_deflate has been requested but can not be built due to prerequisite failures的错误。
解决：
没有安装zlib包。运行命令：
yum install zlib-devel
PHP：
问题：
编译安装php出错mcrypt.h not found. Please reinstall libmcrypt
yum install libmcrypt libmcrypt-devel之后编译，还是报错。
解决：
编译PHP时， –with-mcrypt=/usr/local/libmcrypt/ 加入mcrypt路径。即可解决问题。
./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache2/bin/apxs –with-config-file-path=/usr/local/php/etc –with-mysql=/usr/local/mysql –with-libxml-dir –with-gd –with-jpeg-dir –with-png-dir –with-freetype-dir –with-iconv-dir –with-zlib-dir –with-bz2 –with-openssl –with-mcrypt=/usr/local/libmcrypt/ –enable-soap –enable-gd-native-ttf –enable-mbstring –enable-sockets –enable-exif –disable-ipv6
问题：
configure: error: xml2-config not found. Please check your libxml2 installation.
解决：
yum install -y libxml2-devel
总结：编译安装LAMP前，把事先需要安装的库用yum安装下。避免发生一些错误。
yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
再遇到问题，根据错误提示。解决。一般问题都是因为缺少安装所需要的库导致。
