安装时没有权限写入 wp-config.php

设置apache用户（或者www用户）对WordPress文件夹的写权限（chown -R apache wordpress/）

无法建立目录wp-content/uploads/2015/12。有没有上级目录的写权限？

修改wp-content目录的写权限，方法见上面一条（目录在WordPress站点根目录下），网上也有很多资料说在home目录下，反正我的不是；也有的说修改数据库options中的upload键值，反正我的是没用！！！

安装插件需要输入fpt用户名和密码

查看运行WWW或者Apache的用户，我是直接用vi /etc/passwd 看的，比如：用户名为apache或者www，然后chown -R apache wordpress (wordpress是WordPress站点的根目录)

注册邮箱验证：安装WP Mail SMTP插件
然后设置邮箱服务器，比如使用qq邮箱的：
点击设置->账户->POP3/IMAP/SMIP/Exchange/CardDAV/CalDAV服务，开启服务

使用AMH面板时无法安装插件 Problem with the SSL CA cert (path? access rights?)

AMH面板下载AMCHroot插件，设置中对网站运行环境模式选择兼容模式

邮箱：您的密码重设链接无效,请在下方请求新链接。是因为系统发邮箱是多了<>这两个符号,在wp-login.php中327行上下

// $message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . ">\r\n";
$message .= "". network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') ."\r\n";
还有注册的时候用的：wp-icludes/pluggable.php中1741行左右
// $message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";
$message .= '' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . "";

更改固定链接后找不到页面

方法一：在固定连接前加/index.php即可,比如/index.php/archives/%post_id%，以后每个页面的地址都会有一个index.php
方法二：或者修改服务器rewrite规则（推荐），页面不需要添加Index.pn，更美观
Nginx 解决方案：
在 /etc/nginx/config.d/mysit.conf文件的 loction \ {} 中添加

if (-f $request_filename/index.html){ rewrite (.*) $1/index.html break; }if (-f $request_filename/index.php){ rewrite (.*) $1/index.php; }if (!-f $request_filename){ rewrite (.*) /index.php; }

Apache解决方案：
etc/httpd/conf/httpd.config 文件
原因一：Apache中的rewrite模块没有开启，去除这一行前面的#号就可以了

LoadModule rewrite_module modules/mod_rewrite.so

原因二：AllowOverride Not Enabled；服务器可能没打开AllowOverride。如果httpd.config的AllowOverride设置的是None，那.htaccess将被忽略。找到以下2处位置并修改：

Options FollowSymLinks AllowOverride All # … other directives… AllowOverride All

修改完成后，要重启Apache才能生效。

service httpd restart

AMH解决
进入amh的rewrite规则文件（位置在AMH控制面板虚拟主机那里看）

vi /usr/local/nginx/conf/rewrite/amh.conf

然后添加代码

if (-f $request_filename/index.html){ rewrite (.*) $1/index.html break; }if (-f $request_filename/index.php){ rewrite (.*) $1/index.php; }if (!-f $request_filename){ rewrite (.*) /index.php; }

保存退出
重启虚拟主机

amh host stop amh host start

解决：
主要是因为插件使用了php的mysqli扩展对数据库进行备份，但是php没有装此扩展，需要手动安装。
安装则需要一份类似Windows中的dll文件，linux中是.so文件，这个文件要编译php源码获得，步骤如下：
下载php响应版本的源码
使用php --version 查看版本，
然后下载相同版本的源码并解压
用whereis php查看php安装位置
进入解压的文件夹下/ext/扩展名目录下（扩展名就是想装得扩展的名字）
【WordPress搭建笔记|WordPress搭建笔记遇到的错误笔记】执行/usr/local/php/bin/phpize （phpize是个可执行文件）
发现在ext/扩展名目录下多了一些configure文件
如果没错，继续
./configure --prefix=/usr/local/mysqli --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/local/mysql/bin/mysql_config
这里的目录仍然是你已安装的php所在目录。
如果没有报错，则make，再make install ，然后它会提示你Installing shared extensions: 目录名
看/etc/php.ini中有没有，extension_dir:
有就应该是上一步的目录名，如果不是，改成那个目录名
在最后添加一行：extension=mysqli.so
重启php服务器
