1、 cd /usr/local/src/
2、下载：wget http://nginx.org/download/nginx-1.14.0.tar.gz
3、 cd nginx-1.14.0
4、编译
./configure --prefix=/usr/local/nginx
make & make install
5、 检查配制文件有没有出错： /usr/local/nginx/sbin/nginx -t
6、创建配置文件：
vim /etc/init.d/nginx 并输入以下内容：

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start() 
{
    echo -n $"Starting $prog: "
    mkdir -p /dev/shm/nginx_temp
    daemon $NGINX_SBIN -c $NGINX_CONF
    RETVAL=$?
    echo
    return $RETVAL
}
stop() 
{
    echo -n $"Stopping $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -TERM
    rm -rf /dev/shm/nginx_temp
    RETVAL=$?
    echo
    return $RETVAL
}
reload()
{
    echo -n $"Reloading $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -HUP
    RETVAL=$?
    echo
    return $RETVAL
}
restart()
{
    stop
    start
}
configtest()
{
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac
exit $RETVAL

6、 给权限：chmod 755 /usr/init.d/nginx
7、chkconfig --add nginx
chkconfig nginx on

8、配置它的配置文件：
cd /usr/local/nginx/conf
里面有个nginx.conf文件，我们不用它，用我们自己的所以得备好份 mv nginx.conf nginx.com.bak
vim nginx.conf 输入以下内容：

user nobody nobody;
worker_processes 2;    //定义子进程
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;       //nginxj最多能打开的文件数
events
{
    use epoll;
    worker_connections 6000;      //进程最大的连接数
}
http
{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip ‘$remote_addr $http_x_forwarded_for [$time_local]‘
    ‘ $host "$request_uri" $status‘
    ‘ "$http_referer" "$http_user_agent"‘;
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 30;
    client_header_timeout 3m;
    client_body_timeout 3m;
    send_timeout 3m;
    connection_pool_size 256;
    client_header_buffer_size 1k;
    large_client_header_buffers 8 4k;
    request_pool_size 4k;
    output_buffers 4 32k;
    postpone_output 1460;
    client_max_body_size 10m;
    client_body_buffer_size 256k;
    client_body_temp_path /usr/local/nginx/client_body_temp;
    proxy_temp_path /usr/local/nginx/proxy_temp;
    fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
    fastcgi_intercept_errors on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 8k;
    gzip_comp_level 5;
    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm 
    application/xml;
    server
    {
        listen 80;
        server_name localhost;
        index index.html index.htm index.php;
        root /usr/local/nginx/html;
        location ~ \.php$ 
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

9、启动：/etc/init.d/nginx start
netstat -lntp 查看状态：

二、nginx的默认虚拟主机

1、配制/usr/local/nginx/conf/nginx.conf:
2、去掉里面的这些内容：然后增加一行
include vhost/*.conf


3、创建子目录：
mkdir /usr/local/nginx/conf/vhost
4、增加一个文件:vim default.conf
加入以下内容：

server
{
    listen 80 default_server;  // 有这个标记的就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
}

5、增加 /data/wwwroot/default 目录，定一个html文件
vim index.html
6、检查配置文件有没有写错
/usr/local/nginx/sbin/nginx -t

7、然后重新加载：
/usr/local/nginx/sbin/nginx -s reload

8、测试： curl localhost,

9、哪个在目录/usr/local/nginx/conf/vhost的第一个就是默认虚拟主机
