Nginx 优化（1）：配置文件简单优化

备份配置文件

cd /usr/local/nginx/conf/

mv nginx.conf nginx.conf.source

创建 pid 文件存储目录

mkdir -p /usr/local/nginx/run

chown -R nginx:nginx /usr/local/nginx/run

调整系统文件最大打开数

查看系统当前软资源文件最大打开数

ulimit -Sn

查看系统当前硬资源文件最大打开数

ulimit -Hn

设置系统文件最大打开数（临时生效）

ulimit -HSn 65535

设置系统文件最大打开数（永久生效 - 需重启服务器）

echo "fs.file-max = 65535" >> /etc/sysctl.conf

echo "* - nofile 65535" >> /etc/security/limits.conf

sysctl -p

新建配置文件

vi nginx.conf

    include vhost/*.conf;

        server_name _;
        root /usr/local/src/web_project/nginx_default_project;
        index index.html;

        location /nginx_status {
