php的安装

没想到php的安装出了问题
    缘由在于安装时mysql的支持有问题，由于mysql不 是源码安装的，因此其存放的目录比较多，有些乱

  一、数据库目录
　　/var/lib/mysql/  个人已经改成 /home/data下了
　　二、配置文件
　　/usr/share/mysql（mysql.server命令及配置文件）
　　三、相关命令
　　/usr/bin(mysqladmin mysqldump等命令)

因此 --with mysql=/usr 不对
--with-mysql=/usr/share/mysql  --with-mysqli=/usr/bin/mysql_config   也不行
 难道必须也用源码从新安装一遍mysql吗？ 再继续找找资料，不行就只能从新源码安装Mysql了。
 
通过不懈努力终于解决了
# ./configure  --prefix=/opt/php --with-mysql --with-mysqli  --with-apxs2=/opt/apache2/bin/apxs
出现的问题有两个：
1.
Configure: error: Cannot find MySQL header files under /usr.
Note that tySQL client librhe Mary is not bundled anymore!
解决方法：
  # yum install -y mysql-devel
2.以后又出
configure: error: Cannot find libmysqlclient under /usr.

经查，问题是64位系统中 libmysqlclient 默认安装到了 /usr/lib64/mysql 目录下

而/usr/lib 目录下没有相应文件，可是php编译时，要去 /usr/lib目录下查找，明白缘由，解决办法也就相对简单了

  # cd /usr/lib（先创建mysql文件夹）

  # mkdir  mysql

#ln -s /usr/lib64/mysql/libmysqlclient.* /usr/lib/mysql

即进行符号连接
完成以后
# ./configure  --prefix=/opt/php --with-mysql --with-mysqli  --with-apxs2=/opt/apache2/bin/apxs

Thank you for using PHP.
#make
  
   Build complete.
   Don't forget to run 'make test'.（test 很长呀）
#make install
 
   make: 警告：检测到时钟错误。您的建立多是不完整的。
之前时间设置提早一天，刚才改正确，可能由于apache中午安装是19号，如今成18号出现的问题吧。故直接删除/opt/php从新安装。
此次配置少写 --with mysqli 也正确

Installing PEAR environment:      /opt/php/lib/php/
[PEAR] Archive_Tar    - installed: 1.3.3
[PEAR] Console_Getopt - installed: 1.2.3
[PEAR] Structures_Graph- installed: 1.0.2
[PEAR] XML_Util       - installed: 1.2.1
[PEAR] PEAR           - installed: 1.9.0
Wrote PEAR system config file at: /opt/php/etc/pear.conf
You may want to add: /opt/php/lib/php to your php.ini include_path
Installing PDO headers:          /opt/php/include/php/ext/pdo/
参考INSTALL里接着有：
Setup your php.ini

  cp php.ini-dist /usr/local/lib/php.ini
  接着在httpd.conf中看是否有：
     LoadModule php5_module modules/libphp5.so
和添加
     AddType application/x-httpd-php .php .phtml
完成后启动apache
