MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm
下载
二、安装MySQL
1、二进制安装MySQL，步骤如下：
[root@vm15 mysql]# rpm -ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm
Preparing... ########################################### [100%]
1:MySQL-server-community ########################################### [100%]
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h vm15.example.com password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!
Starting MySQL.. SUCCESS!
Giving mysqld 2 seconds to start
[root@memcache mysql]# rpm -ivh MySQL-client-community-5.1.73-1.rhel5.x86_64.rpm
Preparing... ########################################### [100%]
1:MySQL-client-community ########################################### [100%]
[root@vm15 mysql]# rpm -ivh MySQL-devel-community-5.1.73-1.rhel5.x86_64.rpm
Preparing... ########################################### [100%]
1:MySQL-devel-community ########################################### [100%]
2、验证安装是否成功
[root@vm15 mysql]# rpm -qa |grep MySQL
MySQL-client-community-5.1.73-1.rhel5.x86_64
MySQL-devel-community-5.1.73-1.rhel5.x86_64
MySQL-server-community-5.1.73-1.rhel5.x86_64
[root@vm15 mysql]# mysql
出现了“mysql>”提示符，恭喜你，安装成功！
三、安装Apache
参考：http://www.cnblogs.com/angelasp/p/6446004.html
四、安装libxml2
将下载的libxml2-2.7.4.tar.gz文件上传至/usr/local
[root@vm15 local]# mkdir -p libxml2
[root@vm15 local]# tar -zxvf libxml2-2.7.4.tar.gz
[root@vm15 local]# cd libxml2-2.7.4
[root@vm15 libxml2-2.7.4]# ./configure --prefix=/usr/local/libxml2
[root@vm15 libxml2-2.7.4]# make
[root@vm15 libxml2-2.7.4]# make install
如果安装成功以后，在/usr/local/libxml2/目录下将生成bin、include、lib和share四个目录。在后面安装PHP5源代码包的配置时，会通过在configure命令的选项中加上"--with-libxml-dir=/usr/ local/libxml2"选项，用于指定安装libxml2库文件的位置。
五、安装php
将下载的php-5.6.3.tar.gz文件上传至/usr/local
[root@vm15 local]# mkdir -p php
[root@vm15 local]# tar -zxvf php-5.6.3.tar.gz
[root@vm15 local]# cd php-5.6.3
[root@vm15 php-5.6.3]#./configure --prefix=/usr/local/php --with-mysql --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml-dir=/usr/local/libxml2
这里需要补充一下 网上基本是这样子
后来连接数据库出现了些问题如果链接不上数据库可以是试试这个：
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql --with-mysqli --with-pdo-mysql --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir --with-png-dir --enable-mbstring --enable-xml --with-xpm-dir=/usr --enable-fpm --with-freetype-dir --with-mcrypt --with-mhash --with-gettext --enable-pdo --with-libxml-dir --with-zlib-dir
出现以下信息表示编译成功
..
checking for external oniguruma... no
checking for mcrypt support... no
checking for MSSQL support via FreeTDS... no
checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket... no
configure: error: Cannot find MySQL header files under /usr/local/mysql.

Thank you for using PHP.

[root@vm15 php-5.6.3]#make install
安装成功。
六、配置php
1、配置php.ini，只需要把php-5.6.3安装包中的php.ini-production拷贝到/usr/local/php/lib/下
[root@vm15 php-5.6.3]# cp php.ini-production /usr/local/php/lib/php.ini
2、配置 httpd.conf 让apache支持PHP：
# vi /usr/local/apache/conf/httpd.conf
找到 AddType application/x-gzip .gz .tgz 在其下添加如下内容
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
3、在DirectoryIndex增加 index.php，以便Apache识别PHP格式的index
# vi /usr/local/apache/conf/httpd.conf
<IfModule dir_module>
DirectoryIndex index.html index.php
</IfModule>
七、重启Apache
[root@vm15 mysql]# /usr/local/apache2/bin/apachectl start
（一定要重启）
八、测试php是否成功安装
写一个php测试页info.php，放到/usr/local/apache2/htdocs中。
<?php
phpinfo();
?>;
在浏览器中输入：服务器地址/info.php。通过phpinfo()可以查看很多信息，比如php.ini的存放路径，以及所有扩展组件等，很强大。
如果能正常显示出php的信息，则说明Apche+Mysql+PHP安装成功！
九、安装遇到的问题
1、安装MySQL时，报下面的错误:
[root@memcache mysql]# rpm -ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm
Preparing... ########################################### [100%]

解决方法：yum remove mysql-libs-5*
2、configure php时，报错：
Configuring SAPI modules
checking for AOLserver support... no
checking for Apache 1.x module support via DSO through APXS... configure: error: You have enabled Apache 1.3 support while your server is Apache 2. Please use the appropriate switch --with-apxs2
解决方法：./configure --prefix=/usr/local/php --with-mysql --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml-dir=/usr/local/libxml2
3、安装apr时，报错rm: cannot remove `libtoolT': No such file or directory
解决方法：
直接打开/usr/local/apr-1.5.1/configure 把 $RM“$cfgfile” 那行删除掉
$RM“$cfgfile” 大约在 42302行
[root@vm15 apr-1.5.1]#grep -n RM configure
[root@vm15 apr-1.5.1]#sed -i '/$RM "$cfgfile"/d' configure
然后再重新运行 ./configure --prefix=/usr/local/apr 就可以了.
4、[root@vm15 php-5.6.3]#./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml-dir=/usr/local/libxml2
..
checking for external oniguruma... no
checking for mcrypt support... no
checking for MSSQL support via FreeTDS... no
checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket... no
configure: error: Cannot find MySQL header files under /usr/local/mysql.
Note that the MySQL client library is not bundled anymore!
解决方法：
[root@localhost php-5.5.6]# find / -name mysql.h
/usr/include/mysql/mysql.h
查找到mysql.h文件，我们更改参数为--with-mysql，如果没有的话，请安装mysql-devel包，
