```

从时间上来看，err.log 输出的错误已经不再出现。

另外，更改 install.php ，增加打印标记如下：

```

$config->set('default.module', 'install');
$app->setDebug();

echo '1.04';
/* Run the app. */
$app->parseRequest();
$app->loadModule();

echo '123';

```

输出内容如下：

```

1.01
1.02
1.03

```

看起来好像是这一行出错：

` $app = router::createApp('chanzhi', $s y s t e mRoot);`

s y s t e m/tmp/log 文件夹下只有一个空文件 index.html 

更改  ` error_reporting(0);` 参数0 为 1： ` error_reporting(1);`

install.php 输出：

```

Fatal error : Uncaught Error: Call to undefined function json_encode() in /www/chanzhieps/s y s t e m/config/chanzhieps.php:61 Stack trace: #0 /www/chanzhieps/s y s t e m/config/config.php(122): i n c l u d e() #1 /www/chanzhieps/s y s t e m/framework/base/router.class.php(1902): i n c l u d e('/www/chanzhieps...') #2 /www/chanzhieps/s y s t e m/framework/base/router.class.php(354): baseRouter->loadMainConfig() #3 /www/chanzhieps/s y s t e m/framework/router.class.php(38): baseRouter->__construct('chanzhi', '/www/chanzhieps...') #4 /www/chanzhieps/s y s t e m/framework/router.class.php(56): router->__construct('chanzhi', '/www/chanzhieps...') #5 /www/chanzhieps/www/install.php(28): router::createApp('chanzhi', '/www/chanzhieps...') #6 {main} thrown in  /www/chanzhieps/s y s t e m/config/chanzhieps.php  on line  61

``` 

可见是 json_encode 函数不识别，应该是 json 扩展没有安装。

解决： yum install -y php-json 

问题解决。
