转移 wp-config.php 文件

因为 wp-config.php 默认就是在根目录的，很多人就直接会对准这个目标已经攻击，因此我们还可以让 wp-config.php 文件搬个家～

清空 wp-config,php 的内容，加入：

<?php
if ( !defined('ABSPATH') )
  define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'path/to/wp-config.php');

Let’s Encrypt+Apache虚拟主机上设置

Apache在生成证书后也需要修改一下apache的配置文件 /usr/local/apache/conf/httpd.conf ，查找httpd-ssl将前面的#去掉。
然后再执行：
Apache 2.2如下：

cat >/usr/local/apache/conf/extra/httpd-ssl.conf<<EOF
Listen 443

AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl .crl

SSLCipherSuite EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5
SSLProxyCipherSuite EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5
SSLHonorCipherOrder on

SSLProtocol all -SSLv2 -SSLv3
SSLProxyProtocol all -SSLv2 -SSLv3
SSLPassPhraseDialog builtin

SSLSessionCache "shmcb:/usr/local/apache/logs/ssl_scache(512000)"
SSLSessionCacheTimeout 300

SSLMutex "file:/usr/local/apache/logs/ssl_mutex"

SSLStrictSNIVHostCheck on
NameVirtualHost *:443
EOF

Apache 2.4如下：

cat >/usr/local/apache/conf/extra/httpd-ssl.conf<<EOF
Listen 443

AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl .crl

SSLCipherSuite EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5
SSLProxyCipherSuite EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5
SSLHonorCipherOrder on

SSLProtocol all -SSLv2 -SSLv3
SSLProxyProtocol all -SSLv2 -SSLv3
SSLPassPhraseDialog builtin

SSLSessionCache "shmcb:/usr/local/apache/logs/ssl_scache(512000)"
SSLSessionCacheTimeout 300

Mutex sysvsem default

SSLStrictSNIVHostCheck on
EOF

并在对应apache虚拟主机配置文件的最后下面添加上SSL部分的配置文件：

<VirtualHost *:443>
	DocumentRoot /home/wwwroot/www.xiaokyun.com   #网站目录
	ServerName www.xiaokyun.com:443   #域名
	ServerAdmin admin@xiaokyun.com      #邮箱
	ErrorLog "/home/wwwlogs/www.xiaokyun.com-error_log"   #错误日志
	CustomLog "/home/wwwlogs/www.xiaokyun.com-access_log" common    #访问日志
	SSLEngine on
	SSLCertificateFile /etc/letsencrypt/live/www.xiaokyun.com/fullchain.pem   #改一下里面的域名就行
	SSLCertificateKeyFile /etc/letsencrypt/live/www.xiaokyun.com/privkey.pem    #改一下里面的域名就行

<Directory "/home/wwwroot/www.xiaokyun.com">   #网站目录
	SetOutputFilter DEFLATE
	Options FollowSymLinks
	AllowOverride All
	Order allow,deny
	Allow from all
	DirectoryIndex index.html index.php
</Directory>

</VirtualHost>

需将上述配置根据自己的实际情况修改后，添加到虚拟主机配置文件最后面。注意要重启apache使其实现。
执行：

/etc/init.d/httpd restart

重启Apache使其生效。

Let’s Encrypt+Nginx虚拟主机设置

完整配置如下：

server
{
listen 443 ssl; //如果需要spdy也可以加上,lnmp1.2及其后版本都默认支持spdy,lnmp1.3 nginx 1.9.5以上版本默认支持http2
server_name www.xiaokyun.com; //这里是你的域名
index index.html index.htm index.php default.html default.htm default.php;
root /home/wwwroot/www.xiaokyun.com; //网站目录
ssl_certificate /etc/letsencrypt/live/www.xiaokyun.com/fullchain.pem; //前面生成的证书，改一下里面的域名就行，不建议更换路径
ssl_certificate_key /etc/letsencrypt/live/www.xiaokyun.com/privkey.pem; //前面生成的密钥，改一下里面的域名就行，不建议更换路径
ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;

include wordpress.conf; //这个是伪静态根据自己的需求改成其他或删除
#error_page 404 /404.html;
location ~ [^/].php(/|$)
{
# comment try_files $uri =404; to enable pathinfo
try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf; //lnmp 1.0及之前版本替换为include fcgi.conf;
#include pathinfo.conf;
}

location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}

location ~ .*.(js|css)?$
{
expires 12h;
}

access_log off;
}

需将上述配置根据自己的实际情况修改后，添加到虚拟主机配置文件最后面。

添加完需要执行：

/etc/init.d/nginx reload

重新载入配置使其生效。

如果需要HSTS，可以加上

add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
