Centos7安装nginx

下载、安装

• 依次执行下列命令：

  `
  cd /usr/local/src/
  
  wget http://nginx.org/download/nginx-nginx-1.10.1.tar.gz
  
  tar zxvf nginx-1.10.1.tar.gz -C /usr/local
  
  cd /usr/local/nginx-1.10.1/
  
  ./configure
  
  `
  

• 问题：

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

安装依赖

$ yum install gcc-c++
$ yum install pcre pcre-devel
$ yum install zlib zlib-devel
$ yum install openssl openssl--devel

再次安装nginx

cd /usr/local/nginx-1.10.1/ ./configure make && make install

测试是否可用

cd /usr/local/nginx/sbin ./nginx

• 如果出现如下问题： ` nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) nginx: [emerg] still could not bind()

  `

• 查看80端口占用情况

netstat -ntpl pkill -9 nginx 再次启动./nginx

• 也有可能是防火墙的问题，查看ip是否可以ping通，端口是否开放

升级python后导致yum不可用

vi /usr/bin/yum

修改python头部python为python2.7.5
