ps:一切从简

一、安装所需环境：

    yum -y install gcc gcc-c++ automake pcre pcre-devel zlip zlib-devel openssl openssl-devel 

二、下载及安装nginx

1.下载nginx：wget http://nginx.org/download/nginx-1.8.1.tar.gz

2.解压nginx： tar -xzf nginx-1.8.1.tar.gz

3.添加用户组：groupadd www、useradd -g www www

3.编译nginx：进入解压之后的目录执行 (这里prefix为安装目录)

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

4.安装nginx：make && make install

(安装完成之后：make[1]: Leaving directory `/usr/local/nginx-1.8.1')  无伤大雅

5.验证是否安装成功：/usr/local/nginx/sbin/nginx -V

输出：

nginx version: nginx/1.8.1

built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)

built with OpenSSL 1.0.2k-fips  26 Jan 2017

TLS SNI support enabled

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

三、配置nginx

vi /usr/lib/systemd/system/nginx.service

添加如下：

[Unit]

Description=nginx - high performance web server

Documentation=http://nginx.org/en/docs/

After=network.target remote-fs.target nss-lookup.target

[Service]

Type=forking

PIDFile=/usr/local/nginx/logs/nginx.pid

ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.confExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/bin/kill -s QUIT $MAINPID

PrivateTmp=true [Install]WantedBy=multi-user.target

执行：

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

启动nginx：

systemctl start nginx

设置开机启动：

systemctl enable nginx
