lamp源码安装方法
先安装centos系统，然后更新：
yum -y install apr-devel apr-util check-devel cairo-devel pango-devel libxml2-devel rpmbuild glib2-devel dbus-devel freetype-devel fontconfig-devel gcc-c++ expat-devel python-devel libXrender-devel
mysql 源码包安装
1.useraddmysql
2.passwdmysql(增加密码，可以不用)
3.进入mysql源码包解压目录
cacti安装时的方法：./configure --prefix=/usr/local/mysql --enable-local-infile --with-charset=gbk --with-extra-charsets=all --with-low-memory --with-mysqld-user=mysql --enable-thread-safe-client
4.make
5.makeinstall
cpsupport-files/my-medium.cnf/etc/my.cnf
6.cd/opt/mysql5
7.chown-Rmysql:mysql.
8.bin/mysql_install_db--user=mysql
9.chown-Rroot.
chown-Rmysqlvar
10.bin/mysqld_safe --user=mysql &(启动mysql)11、ln -s /usr/local/mysql/bin/* /usr/local/bin(可以直接运行mysql里面的命令了，不用在打目录)
自启动的配置方法
cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod +x /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
service mysqld start11.bin/mysqladmin shutdown(关闭mysql)
service mysqld stop
apache与php安装
1.进入httpd的解压目录
./configure --enable-so --prefix=/opt/www（普通安装）cacti安装方法：
./configure --prefix=/usr/local/www --enable-so --enable-rewrite --enable-ssl --with-ssl=/usr/local/openssl --with-zlib --enable-mods-shared=all --enable-track-vars --with-mysql=/usr/local/mysql --with-included-apr
make
make install/opt/www/bin/apachectl start|stop
ln -s /opt/www/bin/apachectl /usr/local/bin/apachectl
cp /opt/www/bin/apachectl /etc/rc.d/init.d/httpd
chkconfig --add httpd
chkconfig --list httpd
service httpd start
apache安装好了
2.安装php，进入php解压目录
./configure--with-apxs2=/opt/www/bin/apxs--with-mysql=/opt/mysql5--enable-sockets
说明：
./configure --with-apxs2=/opt/www/bin/apxs(安装好的apache里面的apxs目录) --with-mysql=/opt/mysql5(mysql的安装目录) --enable-sockets(cacti必须要带的参数)
./configure --prefix=/usr/local/php --with-config-file-path=/etc -with-apxs2=/usr/local/www/bin/apxs --enable-fastcgi --enable-safe-mode --with-zlib --with-bz2 --with-freetype-dir --enable-mbstring -with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-gd --with-libxml-dir --with-png-dir --with-jpeg-dir --enable-sockets
(出现要安装的lib库，用yum安装一下，包括库的-devel库)
make
make installcp php.ini-dist /etc/php.ini
(配置目录在./configure里面说明了是/etc)在httpd.conf里面修改：
找到下面字段:
DirectoryIndex
在index.html前面添加index.php
增加：
AddType application/x-httpd-php .php .phtmlAddType application/x-httpd-php-source .phps
3.启动apache /opt/www/bin/apachectl start

========================================
错误解决：
安装apache时类似于以下信息：
“exports.c:1653:error:redefinitionof'ap_hack_apr_version_string'
exports.c:1022:error:previousdefinitionof'ap_hack_apr_version_string'washere
make[2]:***[exports.lo]Error1
make[2]:Leavingdirectory`/usr/local/src/httpd-2.2.＊/server'
make[1]:***[all-recursive]Error1
make[1]:Leavingdirectory`/usr/local/src/httpd-2.2.＊/server'
make: *** [all-recursive] Error 1”有些人说路径不对，有些说perl包不对，有的说zlib不对。
反正有病乱投医。
翻了好久的网页才搞定。
解决办法：
在configure后加上 “--with-included-apr”。
