博客开通以来，主要记录学习和使用过程中遇到的问题及解决方案。文章风格偏向自娱自乐，因此访问量较少，一台1核1G的vps足以支撑网站的正常运行。

后来本站引入三个页面，这三个页面应该对有上外网需求的网友很有帮助，也给本站带来了很大的流量。本站用的WordPress程序，尝试过安装各种缓存插件（super cache, w3 total cache等）加速运行，但是低配的vps依然难以支持这么大的访问量。通过日志可以看到随着访问量的增加，php-fpm进程增多，Mysql的连接和线程增多，接着出现OOM，然后系统kill掉占用内存最大的Mysql进程，于是网站进入503宕机模式。

买更好的vps能解决访问量大的问题，但是要花更多的钱。做为一个技术宅，首先想到的当然是如何榨干现有机器来支撑大流量。做过的尝试包括切换到比WordPress性能更好的Ghost，参考：尝试Ghost 。但是相对于WordPress，Ghost的生态远没有那么成熟，最终放弃了。

左思右想下，终极解决办法是用Nginx缓存，最初的文章可参考：Nginx配置fastcgi cache。fastcgi\_cache的好处是大部分用户的请求不用后端php-fpm打交道，直接发送缓存的静态页面，速度上甩各种WordPress插件好几条街！相比之下wordpress的各种插件还要执行php，也避免不了访问数据库，弱爆了！

自从使用了nginx缓存，网站平稳运行，再也没有出现过宕机的现象。同时vps的cpu和内存占用率直线下降，再也无需担心vps的配置问题，感觉再来10倍流量博客也撑得住！

因为nginx稳如狗的体验，所以现在对于博客类读多写少的产品都是强推nginx缓存（fastcgi缓存或者proxy缓存）。鉴于可能帮到一些网友，现贴出 /etc/nginx/nginx.conf 配置文件供网友参考（包含ssl设置和gzip部分）：

以及用于WordPress站点的网站配置文件（/etc/nginx/conf.d/tlanyan.conf）:

server {
    listen 80;
    listen \[::\]:80;
    server\_name www.tlanyan.me tlanyan.me; # 请换成自己的域名
    rewrite ^(.\*) https://$server\_name$1 permanent;
}
server {
    listen       443 ssl http2;
    listen       \[::\]:443 ssl http2;
    server\_name www.tlanyan.me tlanyan.me; # 请换成自己的域名
    charset utf-8;
    ssl\_certificate /etc/nginx/conf.d/tlanyan.pem;  # 请换成自己的证书和密钥
    ssl\_certificate\_key /etc/nginx/conf.d/tlanyan.key;
    set $host\_path "/var/www/tlanyan";  # 请改成自己的路径
    access\_log  /var/log/nginx/tlanyan.access.log  main buffer=32k flush=30s;
    error\_log /var/log/nginx/tlanyan.error.log;
    root   $host\_path;
    # 缓存标记
    set $skip\_cache 0;
    if ($query\_string != "") {
        set $skip\_cache 1;
    }
    if ($request\_uri ~\* "/wp-admin/|/xmlrpc.php|wp-.\*.php|/feed/|sitemap(\_index)?.xml") {
        set $skip\_cache 1;
    }
    # 登录用户或发表评论者
    if ($http\_cookie ~\* "comment\_author|wordpress\_\[a-f0-9\]+|wp-postpass|wordpress\_no\_cache|wordpress\_logged\_in") {
        set $skip\_cache 1;
    }
    location = / {
        index  index.php index.html;
        try\_files /index.php?$args /index.php?$args;
    }
    location / {
        index  index.php index.html;
        try\_files $uri $uri/ /index.php?$args;
    }
    location ~ ^/\\.user\\.ini {
            deny all;
    }
    location ~ \\.php$ {
        try\_files $uri =404;
        fastcgi\_index index.php;
        fastcgi\_pass   127.0.0.1:9000;
        fastcgi\_cache tlanyan;
        fastcgi\_cache\_valid 200 301 302 30m;
        fastcgi\_cache\_valid 404 10m;
        fastcgi\_cache\_bypass $skip\_cache;
        fastcgi\_no\_cache $skip\_cache;
        fastcgi\_cache\_lock on;
        include fastcgi\_params;
        fastcgi\_param  SCRIPT\_FILENAME  $document\_root$fastcgi\_script\_name;
    }
    location ~ \\.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar|jpeg)$ {
        expires max;
        access\_log off;
        try\_files $uri =404;
    }
}

上述配置对最新版的Nginx测试有效，详细配置指令请参考Nginx官方文档。
