微擎系统需要的PHP扩展,微擎系统配置文件/data/config.php相关设置

配置文件路径：

/data/config.php

修改方法：

修改对应数组的参数即可生效。

数据库配置

微擎系统支持数据库的主从配置(一主多从)，只需要进行简单的配置即可。

变量描述$config[‘db’][‘master’][‘host’]数据库主机地址$config[‘db’][‘master’][‘username’]数据库用户名$config[‘db’][‘master’][‘password’]数据库密码$config[‘db’][‘master’][‘port’]数据库端口$config[‘db’][‘master’][‘database’]数据库名$config[‘db’][‘master’][‘charset’]数据库编码$config[‘db’][‘master’][‘pconnect’]数据库连接类型$config[‘db’][‘master’][‘tablepre’]数据库表前缀$config[‘db’][‘slave_status’]读写分离开关$config[‘db’][‘slave’][‘1’]只读实例配置项，1为只读实例编码，多台实例可新增[2],[3],[4]$config[‘db’][‘common’][‘slave_except_table’]不进行主从分离的表

配置主从支持在系统 “data/config.php” 文件中，部分用户没有master项，

$config['db']['host']

等同于

$config['db']['master']['host']

，具体配置如下：

示例：

//主库配置

$config['db']['master']['host'] = '192.168.1.2';

$config['db']['master']['username'] = 'root';

$config['db']['master']['password'] = '123456';

$config['db']['master']['port'] = '3306';

$config['db']['master']['database'] = 'we7_pro';

$config['db']['master']['charset'] = 'utf8';

$config['db']['master']['pconnect'] = 0;

$config['db']['master']['tablepre'] = 'ims_';

//以下选项，如果没有请自行添加

//从库配置

$config['db']['slave_status'] = false; //是否开启主从配置

$config['db']['slave']['1']['host'] = '192.168.1.3'; //从库配置要与主库相同

$config['db']['slave']['1']['username'] = 'root';

$config['db']['slave']['1']['password'] = '123456';

$config['db']['slave']['1']['port'] = '3306';

$config['db']['slave']['1']['database'] = 'we7_pro';

$config['db']['slave']['1']['charset'] = 'utf8';

$config['db']['slave']['1']['pconnect'] = 0;

$config['db']['slave']['1']['tablepre'] = 'ims_';

$config['db']['slave']['1']['weight'] = 0; //从库的权重值，默认0即可

//不进行主从分离的表

$config['db']['common']['slave_except_table'] = array(

'core_sessions',

);
