主从配置 有调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。 配置主从支持在系统 "data/config.php" 文件中，具体配置如下： 注：部分用户没有master项，$config['db']['host'] 等同于 $config['db']['master']['host'] ~~~ //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', ); ~~~
