php网站部署故障处理

1、网站无法访问网站的安装页面install.php，提示：

Uncaught exception 'Think\Exception' with message 'Access denied for user 'apache'@'localhost' (using password: NO)' in /var/www/html/src/ThinkPHP/Common/functions.php:105 Stack trace: #0 /var/www/html/src/ThinkPHP/Library/Think/Db/Driver/Mysqli.class.php(45): E('Access denied f...') #1 /var/www/html/src/ThinkPHP/Library/Think/Db.class.php(166): Think\Db\Driver\Mysqli->connect() #2

......

错误位置

FILE: /var/www/html/src/ThinkPHP/Common/functions.php 　LINE: 105

原因分析：apache没有权限；

解决方法：提升apache权限，使之可访问网站目录*；

chown -R apache:apache /var/www/html/src/*

2、UCenter网站后台安装完成后，点击下一步无法跳转至用户管理中心？

原因分析：admin.php在网站目录下，但提示页面未发现；

查看数据库记录，仅有一个表有数据；

解决方法：重新更换源码包即可*。

3、网站无法使用旧版本php解析？

原因分析：安装时使用了默认版本或版本过低。

解决方法：安装指定php版本（以php7.1.*为例）；指令为如下所述。

yum -y remove php*

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum repolist all
yum -y install php71w php71w-pear php71w-devel #安装php7.1版本
php -v
systemctl restart httpd

2、网站不能正常解析？http error500？

原因分析：内部服务器错误。

解决方法：

sed -i 's/display_errors = Off/display_errors = On/' /etc/php.ini
sed -i 's/display_startup_errors = Off/display_startup_errors = On/' /etc/php.ini

systemctl restart httpd

3、网站无法访问install.php？

Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

Fatal error: Unknown: Failed opening required '/var/www/html/install.php' (include_path='.:/usr/share/pear:/usr/share/php') in Unknown on line 0

原因分析：install.php无可执行权限。

解决方法：chmod 750 install.php

4、网站安装时，无法配置时区？

Warning: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /var/www/html/ecshop/ECShop_V4.0.7_UTF8_release20200102/source/ecshop/install/includes/lib_installer.php on line 224
