下载

    http://nginx.org/

准备环境:

    useradd -g www www

配置:

        ./configure \
        --user=www \
        --group=www \
        --prefix=/usr/local/nginx \
        --with-http_ssl_module \
        --with-http_stub_status_module \
        --with-http_realip_module \
        --with-threads

编译

    make

安装

    make install

验证

/usr/local/nginx/sbin/nginx -V

创建软连接:

ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx

开机自启动

    vim /etc/init.d/nginx

输入

    #!/bin/sh

            exit 2
    esac

赋予脚本可执行权限

    chmod a+x /etc/init.d/nginx

将nginx服务加入chkconfig管理列表

    chkconfig --add /etc/init.d/nginx
    chkconfig nginx on
    # 启动
    systemctl start nginx

配置优化

    下列配置在nginx.conf里与http节点同级

    user  www www;
    worker_processes auto;
    
    events
        {
            use epoll;
            worker_connections 51200;
            multi_accept on;
        }

http节点下加入下列配置,将会从指定目录加载配置文件

    include /usr/local/nginx/conf/servers/*.conf;
