centos7下nginx的配置

在Centos下,yum源不提供nginx的安装,可以通过切换yum源的方法获取安装。也可以通过直接下载安装包的方法。
**以下命令均需root权限执行**:
首先安装必要的库(nginx 中gzip模块需要 zlib 库,rewrite模块需要 pcre 库,ssl 功能需要openssl库)。选定**/usr/local**为安装目录,以下具体版本号根据实际改变。
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PCRE库
cd /usr/local/                                                       
wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.33/pcre-8.33.tar.gz                                                                  
tar -zxvf pcre-8.33.tar.gz                                           
cd pcre-8.33                                                         
./configure                                                          
make && make install                                                 
3. 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                                                 
4. 安装zlib库存
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                                                 
5. 安装nginx
cd /usr/local/                                                       
wget http://nginx.org/download/nginx-1.8.0.tar.gz                    
tar -zxvf nginx-1.8.0.tar.gz                                         
cd nginx-1.8.0                                                       
./configure --user=nobody --group=nobody --prefix=/usr/local/nginx   --with-http_stub_status_module --with-http_gzip_static_module    --with-http_realip_module --with-http_sub_module    --with-http_ssl_module --with-pcre=/usr/local/pcre-8.33    --with-zlib=/usr/local/zlib-1.2.11                                   
(注: --with-http_ssl_module:这个不加后面在nginx.conf配置ssl:on后,启动会报nginx: [emerg] unknown directive "ssl" in /opt/nginx/conf/nginx.conf 异常)
make && make install                                                 
6.启动
/usr/local/nginx/sbin/nginx                                          
检查是否启动成功:
1.先看nginx进程中有没有;命令:
ps -ef | grep nginx                                                  
\
2.再看端口在不命令:
netstat -lnt |grep 80                                                
\
3.在添加下80端口测
firewall-cmd --zone=public --add-port=80/tcp --permanent    (--permanent永久生效,没有此参数重启后失效)
输入重新载入命令:
firewall-cmd --reload                                                
打开浏览器访问此机器的 IP,如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。
