linux安装nginx

1、安装nginx前首先安装下面几个依赖

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

2、到/usr/local/src下下载nginx

cd /usr/local/src

wget http://nginx.org/download/nginx-1.9.9.tar.gz

3、解压nginx

tar -xzvf nginx-1.9.9.tar.gz

 4、移动nginx到/usr/local/nginx下

创建nginx文件夹

mkdir /usr/local/nginx

移动

mv /usr/local/src/nginx-1.9.9/* /usr/local/nginx

5、进入到/usr/local/nginx

cd /usr/local/nginx

6、初始化

创建nginx初始化地址

mkdir /usr/local/webserver

mkdir /usr/local/webserver/nginx

初始化  考虑到后续安装ssl证书 添加两个模块 --with-http_stub_status_module --with-http_ssl_module

./configure --with-http_stub_status_module --with-http_ssl_module --prefix=/usr/local/webserver/nginx

yum -y install gcc openssl openssl-devel pcre-devel zlib zlib-devel 

make

make install

make错误解决

 1、如果在make时提示这个就到objs文件夹下编辑Makefile文件 找到下面这句话然后去掉：-Werror

	
CFLAGS =  -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g　　

 如果提示这个

 在nginx安装文件夹下输入

vim src/os/unix/ngx_user.c

找到 cd.current_salt[0] = ~salt[0]; 注释掉

7、编辑webserver/nginx/conf 下的nginx.conf文件(ip跟域名改成自己的还有一些地址也修改成自己的)

user root;
worker_processes 4; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;

 #下面是server虚拟主机的配置
 server
  {
    listen 80;#监听端口

    index index.html index.htm index.php;
    root /etc/nginx/html;#站点目录
    #error_page   502             /502.html;
    #location = /502.html {
    #    root   /usr/local/webserver/nginx/html/error;
    #} 
    location /miai {
        set $origin '*';
        if ($http_origin) {
            set $origin "$http_origin";
        }
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' "$origin";
            add_header 'Access-Control-Allow-Credentials' "true";
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'content-type, authorization, x-requested-with, token, userType'; ##注意，此处的token 取决于开发，有时候是user-token or doctor-token等。
            add_header 'Content-Length' 0;
            add_header 'Content-Type' 'text/plain, charset=utf-8';
            return 204;
        }
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Accept-Encoding 'gzip';
        proxy_pass http://127.0.0.1:8080;
    }
    location /imgs/ {
        root /usr/local/project/;
    }

  }
}

8、启动

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