linux 安装nginx

1. 安装gcc gcc-c++(如新环境,未安装请先安装)
   $ yum install -y gcc gcc-c++
2. 安装wget
   $ yum -y install wget
3. 安装PCRE库
   $ cd /usr/local/
   $ wget https://sourceforge.net/projects/pcre/files/pcre/8.43/pcre-8.43.tar.gz
   $ tar -zxvf pcre-8.43.tar.gz
   $ cd pcre-8.43
   $ ./configure
   $ make && make install
   如果报错:
   在 linux 中执行 wget 命令提示 -bash: wget: command not found
   解决办法 yum -y install wget
4. 安装SSL库
   $ cd /usr/local/
   $ wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz
   $ tar -zxvf openssl-1.0.1j.tar.gz
   $ cd openssl-1.0.1j
   $ ./config
   $ make && make install
5. 安装zlib库
   $ cd /usr/local/
   $ wget http://zlib.net/zlib-1.2.11.tar.gz
   $ tar -zxvf zlib-1.2.11.tar.gz
   $ cd zlib-1.2.11
   $ ./configure
   $ make && make install
6. 安装nginx
   $ cd /usr/local/
   $ wget http://nginx.org/download/nginx-1.9.9.tar.gz
   $ tar -zxvf nginx-1.9.9.tar.gz
   $ cd nginx-1.9.9
   $ ./configure
   $ make && make install
7. 启动nginx
   /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

    #下面是server虚拟主机的配置
    server
     {
       listen 80;#监听端口
       server_name localhost;#域名
       index index.html index.htm index.php;
       root /usr/local/webserver/nginx/html;#站点目录
         location ~ .*\.(php|php5)?$
       {
         #fastcgi_pass unix:/tmp/php-cgi.sock;
         fastcgi_pass 127.0.0.1:9000;
         fastcgi_index index.php;
         include fastcgi.conf;
       }
       location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$

   检查配置文件nginx.conf的正确性命令：
   [root@bogon conf]# /usr/local/nginx/sbin/nginx -t

9. Nginx 其他命令
   /usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件
   /usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx
   /usr/local/nginx/sbin/nginx -s stop # 停止 Nginx

10. Nginx目录结构
    Nginx:

    conf   配置目录
    contrib
    docs 文档目录
    logs  日志目录
    temp 临时文件目录
