linux下安装配置nginx并配置

一，安装nginx
有问题一步步来
nginx下载地址： http://nginx.org/en/download.html
把下载好的nginx版本放到/usr/local中
1.1 解压

[root@vw010001135067 ~]# cd /usr/local/
[root@vw010001135067 local]# tar -zvxf nginx-1.10.2.tar.gz

1.2 进入nginx文件夹，执行./configure命令

[root@vw010001135067 local]# cd nginx-1.10.2
[root@vw010001135067 nginx-1.10.2]# ./configure

报错如下：

checking for OS
 + Linux 2.6.32-431.el6.x86_64 x86_64
checking for C compiler ... not found
 
./configure: error: C compiler cc is not found

出现这个错误。那么就是gcc 包没有安装。

1.2.1 安装gcc
查看gcc

[root@vw010001135067 nginx-1.10.2]# whereis gcc

安装gcc

[root@vw010001135067 nginx-1.10.2]# yum -y install gcc

安装成功后再次查看

[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

gcc安装好了。

1.2.2 继续执行./configure

[root@vw010001135067 nginx-1.10.2]# ./configure
checking for OS
 + Linux 2.6.32-431.el6.x86_64 x86_64

......

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

1.2.3 出现如上错误。安装pcre-devel

[root@vw010001135067 nginx-1.10.2]# yum install pcre-devel

再次执行./configure

error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.

如果有这个错误 那么执行

yum install zlib-devel

1.2.4 执行./configure后没有报错

[root@vw010001135067 nginx-1.10.2]# ./configure
checking for OS
 + Linux 2.6.32-431.el6.x86_64 x86_64

1.3 如果你想使用openssl 功能，sha1 功能。 那么安装openssl ，sha1 吧

[root@vw010001135067 nginx-1.10.2]# yum install openssl openssl-devel 
[root@vw010001135067 nginx-1.10.2]# install perl-Digest-SHA1.x86_64

1.3.1 开启ssl 模块 执行./configure –with-http_ssl_module

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_ssl_module

1.3.2 启用“server+status”页，执行./configure –with-http_stub_status_module

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module

上面两个命令同时启动可以

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module --with-http_ssl_module

1.4 上面configure就通过了

执行make 命令，执行make install 命令

[root@vw010001135067 nginx-1.10.2]# make
[root@vw010001135067 nginx-1.10.2]# make install

至此，nginx 执行成功了

1.5 配置环境变量

在/etc/profile 中加入配置
打开配置文件

[root@vw010001135067 nginx-1.10.2]# vi /etc/profile

在配置文件中加入

#nginx configure
export NGINX_HOME=/usr/local/nginx-1.10.2
export PATH=$PATH:$NGINX_HOME/sbin

我开始像上面填写，结果nginx -v的时候查找不到。注意到上面我的nginx_home配置的地址不对。先找到nginx的安装地址

[root@vw010001135067 nginx-1.10.2]# whereis nginx
nginx: /usr/local/nginx

还真是地址写错了，把上面的改成

#nginx configure
export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin

编译完保存退出并执行

[root@vw010001135067 nginx-1.10.2]# source /etc/profile

使配置生效。

1.6 查看nginx版本

查看nginx版本

[root@vw010001135067 nginx]# nginx -v
nginx version: nginx/1.10.2

整个过程成功了！

二、修改nginx.conf
2.1 启动nginx

nginx -c conf/nginx.conf

我的nginx服务在http://10.1.135.67/，配置成功后，现在启动nginx
启动成功，在浏览器打开http://10.1.135.67/，默认端口号80.

如上图，nginx已经正常工作了。

2.2 配置tomcat服务
现在我的tomcat服务在10.1.29.15，需要通过nginx转发。那么打开nginx.conf，修改配置文件。如下，添加：

#user nobody;
worker_processes 1;
 
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
 
#pid  logs/nginx.pid;
 
 
events {
 worker_connections 1024;#最大连接数，默认为512
 accept_mutex on; #设置网路连接序列化，防止惊群现象发生，默认为on
 multi_accept on; #设置一个进程是否同时接受多个网络连接，默认为off
 #use epoll;  #事件驱动模型，select|poll|kqueue|epoll|resig|/dev/poll|eventport 
}
 
 
http {
 #文件扩展名与文件类型映射表
 include  mime.types;
 
 #默认文件类型，默认为text/plain 
 default_type application/octet-stream;
 
 #自定义格式
 log_format main '$remote_addr - $remote_user [$time_local] "$request" '
      '$status $body_bytes_sent "$http_referer" '
      '"$http_user_agent" "$http_x_forwarded_for"'; 
 
 #combined为日志格式的默认值
 access_log logs/access.log main;
 
 #允许sendfile方式传输文件，默认为off，可以在http块，server块，location块
 sendfile  on;
 sendfile_max_chunk 100k; #每个进程每次调用传输数量不能大于设定的值，默认为0，即不设上限。
 
 #tcp_nopush  on;
 
 #连接超时时间，默认为75s，可以在http，server，location块。
 keepalive_timeout 65;
 
 #gzip on;
 
 upstream upload {
  server 10.1.29.15:8080;
 } 
 
 error_page 404 https://www.baidu.com; #错误页
 
 server {
  keepalive_requests 120; #单连接请求上限次数。
  listen  80; #监听端口
  server_name localhost; #监听地址 
 
  #charset koi8-r;
 
  #access_log logs/host.access.log main;
 
  location  /  {
	  proxy_connect_timeout 15s;
	  proxy_send_timeout 15s;
	  proxy_read_timeout 30m;//这个是服务器对你等待最大的时间，也就是说，当你webSocket使用nginx转发的时候，如果30分钟内没有通讯，依然是会断开的，所以，你可以按照你的需求来设定
	  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 Connection "";
	  proxy_set_header Upgrade $http_upgrade;//这是webSocket的配置
      proxy_set_header Connection "upgrade";//这是webSocket的配置
	  proxy_pass http://upload; #请求转向upload 定义的服务器列表
	  client_max_body_size 1024m;
   } 
 }
}

配置好后，保存配置文件，并且重启nginx

[root@vw010001135067 nginx]# nginx -s reload

在浏览器调用upload项目是否成功

如图能正确访问项目，配置成功！
