如有可能,请勿使用openvz的VPS,太他么蛋疼了。
官方提供的解决办法可能不适用
于多种情况,比如我的

例如,我的VPS压根就没有epel源,所以我们先安装一下
系统为centos6
yum install epel-release #EPEL官方源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo #阿里云基础源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo #阿里云epel源
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm #remi源
yum clean all 清理缓存
yum makecache 生成列表
然后安装官方提示的方式安装
wget -O /www/server/panel/certbot-auto http://download.bt.cn/install/certbot-auto.init -T 5
chmod +x /www/server/panel/certbot-auto && /www/server/panel/certbot-auto -n
会出现各种错误,我们一一解决
You are using pip version 8.0.3, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command
pip版本太低,我们升级
pip install --upgrade pip
安装完后会提示Successfully installed pip-9.0.1
再运行官方的脚本,错误变得更多了
pip prints the following errors:

但并不是我们做错了,继续修复
因为我们已经填了很多源,直接yum update
升级成功
Updated:
libmcrypt.x86_64 0:2.5.8-9.el6 mcrypt.x86_64 0:2.6.8-10.el6 mhash.x86_64 0:0.9.
然后更新下python
yum update python*
更新完成
Updated:
python.x86_64 0:2.6.6-66.el6_8 python-devel.x86_64 0:2.6.6-66.el6_8 python-libs.x86_64 0:2.6.6-66.el6_8
python-tools.x86_64 0:2.6.6-66.el6_8
Dependency Updated:
tkinter.x86_64 0:2.6.6-66.el6_8
Complete!
最后我们再运行官方的安装脚本,安装成功

有很多用户跟模板兔反应在wp默认页面注册时,提示点击链接设置密码,可是点击后会提示“要设置您的密码,请访问以下地址:”。这里模板兔提供一个比较死板的方法,就是修改默认的wp-login.php文件。
1.修改wordpress目录下的 wp-login.php文件将
$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . ">\r\n";
修改为:
$message .=network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . "\r\n";
2.wordpress安装目录下的/wp-includes/pluggable.php文件
将:
$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";
修改为:
$message .= network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . "\r\n\r\n";
即两个文件代码去掉左右的<,>即可。
当你的WordPress中的文章达到上万篇,随着流量的增加,Wordpress的服务器压力也随之不断加大,Wordpress发布文章和后台相关的操作都会变得缓慢,这时如果单从硬件上投入来提高Wordpress性能显然不划算。
利用Redis将WordPress页面直接缓存在服务器的内存中,这样在避免了PHP重复执行操作的同时,内存的极速响应能够最大限度地提升Wordpress页面的访问速度,实际测试发现页面执行时间可以降低到0.00X秒级别,比没有使用Redis缓存提升几倍甚至十几倍以上。
现在就分享一下折腾教程,很简单(主要是宝塔太强大方便!)
首先,我们要安装redis扩展:
很简单就可以安装好了,在php那的扩展配置安装即可。
用Predis.php作为Redis的PHP客户端
我们可以使用Predis.php来作为PHP客户端,直接将Predis.php下载并上传到Wordpress的根目录下。
下载Predis.php
安装Redis前端缓存的PHP脚本
速度飕飕滴!
