在mysql-cluster中,如果想把某个SQL节点升级为Web服务器,那么我们需要在该节点上安装php以及php对mysql的扩展模块,,但是会出现冲突。

    安装php的命令为:# php53 默认情况下会安装依赖包:php53-cli、php53-common


    安装mysql扩展的命令为:# php53-mysql 此时会出现冲突,如果采用强制安装的形式是否会影响使用并没有测试;

    通过在一台已经配置好扩展模块的机器(不是集群中的SQL节点)上查看安装目录:


    # rpm -ql php53-mysql-5.3.3-13.el5_8


    提示结果:

    /etc/php.d/mysql.ini
    /etc/php.d/mysqli.ini
    /etc/php.d/pdo_mysql.ini
    /usr/lib64/php/modules/mysql.so
    /usr/lib64/php/modules/mysqli.so
    /usr/lib64/php/modules/pdo_mysql.so

    只是几个相关文件,如果把这些文件拷贝到集群中sql节点的相应目录下,是不是该功能即可发挥出来。

    # rpm -ql php53-5.3.3-13.el5_8
    /etc/httpd/conf.d/php.conf
    /usr/lib64/httpd/modules/libphp5.so
    /var/lib/php/session
    /var/www/icons/php.gif
   


    在Linux集群环境下的SQL节点上如果想使用mysql扩展,则有尝试办法:

    # cd /etc/ # mkdir php.d # cd php.d # vi apc.ini.rpmsave


    在apc.ini.rpmsave这个文件中输入如下内容:

    ; Enable apc extension module
    extension = apc.so
    ; Options for the apc module
    apc.enabled=1
    apc.shm_segments=1
    apc.optimization=0
    apc.shm_size=512
    apc.ttl=7200
    apc.user_ttl=7200
    apc.num_files_hint=1024
    apc.mmap_file_mask=/tmp/apc.XXXXXX
    apc.enable_cli=1
    apc.cache_by_default=1;


    拷贝mysql.ini、mysqli.ini、pdo.ini、pdo_mysql.ini、mysql.so、mysqli.so、pdo.so、pdo_mysql.so、apc.so到相应目录。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
