先安裝centos系統，然後更新：
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 源碼包安裝
1.useradd mysql
2.passwd mysql(增加密碼，可以不用)
3.進入mysql源碼包解壓目錄
cacti安裝時的方法：
./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.make install
cp support-files/my-medium.cnf /etc/my.cnf
6.cd /opt/mysql5
7.chown -R mysql:mysql .
8.bin/mysql_install_db --user=mysql
9.chown -R root .
chown -R mysql var
10.bin/mysqld_safe --user=mysql &(啓動mysql)
11、ln -s /usr/local/mysql/bin/* /usr/local/bin(可以直接運行mysql裏面的命令了，不用在打目錄)
自啓動的配置方法
cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod +x /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
service mysqld start
11.bin/mysqladmin shutdown(關閉mysql)
service mysqld stop
apache與php安裝
1.進入httpd的解壓目錄
./configure --enable-so --prefix=/opt/www（普通安裝）
cacti安裝方法：
./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安裝好了
2.安裝php，進入php解壓目錄
./configure --with-apxs2=/opt/www/bin/apxs --with-mysql=/opt/mysql5 --enable-sockets
說明：
./configure --with-apxs2=/opt/www/bin/apxs(安裝好的apache裏面的apxs目錄) --with-
mysql=/opt/mysql5(mysql的安裝目錄) --enable-sockets(cacti必須要帶的參數)
./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
(出現要安裝的lib庫，用yum安裝一下，包括庫的-devel庫)
make
make install
cp php.ini-dist /etc/php.ini
(配置目錄在./configure裏面說明了是/etc)
在httpd.conf裏面修改：
找到下面字段:
DirectoryIndex
在index.html前面添加index.php
增加：
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
3.啓動apache
/opt/www/bin/apachectl start

========================================
錯誤解決：
安裝apache時類似於以下信息：
“exports.c:1653: error: redefinition of 'ap_hack_apr_version_string'
exports.c:1022: error: previous definition of 'ap_hack_apr_version_string' was here
make[2]: *** [exports.lo] Error 1
make[2]: Leaving directory `/usr/local/src/httpd-2.2.＊/server'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/httpd-2.2.＊/server'
make: *** [all-recursive] Error 1”
有些人說路徑不對，有些說perl包不對，有的說zlib不對。
反正有病亂投醫。
翻了好久的網頁才搞定。
解決辦法：
在configure後加上 “--with-included-apr”。
