详解用nginx+WordPress搭建个人博客全流程(2)-木庄网络博客

然后配置一个HTTP服务，以Nginx为例：

server {
  server_name www.nomansky.xyz nomansky.xyz;

  location ^~ /.well-known/acme-challenge/ {
    alias /home/wordpress/challenges/;
    try_files $uri =404;
  }

  location / {
    rewrite ^/(.*)$ https://nomansky.xyz/$1 permanent;
  }
}

以上配置表示查找 /home/wordpress/challenges/ 目录下的文件，如果找不到就重定向到 HTTPS 地址。这个验证服务以后更新证书还要用到，要一直保留。

接下来把acme-tiny保存到ssl目录wget https://raw.githubusercontent.com/diafygi/acme-tiny/master/acme_tiny.py

然后指定账户私钥、CSR 以及验证目录，执行脚本python acme_tiny.py --account-key ./account.key --csr ./domain.csr --acme-dir /home/wordpress/challenges/ > ./signed.crt,看到如下图所示，则说明生成成功了

最后还要下载Let's Encrypt 的中间证书，配置HTTPS证书时既不要漏掉中间证书，也不要包含根证书。在 Nginx 配置中，需要把中间证书和网站证书合在一起：

wget -O - https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem > intermediate.pem
cat signed.crt intermediate.pem > chained.pem

为了后续能顺利启用OCSP Stapling，我们再把根证书和中间证书合在一起(此步也可省略）

wget -O - https://letsencrypt.org/certs/isrgrootx1.pem > root.pem
cat intermediate.pem root.pem > full_chained.pem

Let's Encrypt签发的证书只有90天有效期，推荐使用脚本定期更新。创建一个renew_cert.sh并通过chmod a+x renew_cert.sh赋予执行权限。文件内容如下：

#!/bin/bash

cd /etc/nginx/ssl/
python acme_tiny.py --account-key account.key --csr domain.csr --acme-dir /home/wordpress/challenges/ > signed.crt || exit
wget -O - https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem > intermediate.pem
cat signed.crt intermediate.pem > chained.pem
systemctl restart nginx

在crontabl中配置定时任务0 0 1 * * /etc/nginx/ssl/renew_cert.sh >/dev/null 2>&1

0x07 下载WordPress并配置Nginx

将WordPress下载到/home/wordpress/目录下wget https://wordpress.org/latest.tar.gz

tar zxvf latest.tar.gz解压WordPress文件

chown -R wordpress:wordpress wordpress将wordpress目录的所有者改为wordpress用户

接着，打开vim /etc/nginx/nginx.conf将nginx的运行角色改为wordpress

···
user wordpress;
worker_processes auto;
···

然后这里我把处于解耦合的目的，把主配置文件nginx.conf里的server配置块注释掉

新建sudo mkdir /etc/nginx/snippets目录并vim letsencrypt.conf来将以下配置粘贴到里面

location ^~ /.well-known/acme-challenge/ {
   alias /home/wordpress/challenges/;
   try_files $uri =404;
}

接下来新建vim /etc/nginx/conf.d/wordpress.conf配置文件，修改成如下配置

 # Redirect HTTP -> HTTPS
  server {
    listen 80;
    server_name www.nomansky.xyz nomansky.xyz;

    include snippets/letsencrypt.conf;
    return 301 https://nomansky.xyz$request_uri;
  }

  # Redirect WWW -> NON WWW
  server {
    listen 443 ssl http2;
    server_name www.nomansky.xyz;

    ssl_certificate /etc/nginx/ssl/chained.pem;
    ssl_certificate_key /etc/nginx/ssl/domain.key;

    return 301 https://nomansky.com$request_uri;
  }

  server {
    listen 443 ssl http2;
    server_name nomansky.com;

    root /home/wordpress/wordpress;
    index index.php;

    # SSL parameters
    ssl_certificate /etc/nginx/ssl/chained.pem;
    ssl_certificate_key /etc/nginx/ssl/domain.key;

    # log files
    access_log /home/wordpress/log/nomansky.xyz.access.log;
    error_log /home/wordpress/log/nomansky.xyz.error.log;

    location = /favicon.ico {
      log_not_found off;
      access_log off;
    }
    
          location = /robots.txt {
      allow all;
      log_not_found off;
      access_log off;
    }

    location / {
      try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
      try_files $uri =404;
      fastcgi_pass unix:/run/php-fpm/www.sock;
      fastcgi_index  index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include fastcgi_params;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
      expires max;
      log_not_found off;
    }

创建日志目录mkdir -p /home/wordpress/log,并设置权限chown -R wordpress:wordpress /home/wordpress/log

nginx -t查看是否是否语法检查正常，如正常则nginx -s reload重载nginx

接下来看到WordPress页面成功打开了，就此大功告成啦
