下载并解压安装包
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar -zvxf nginx-1.14.2.tar.gz
进入解压后的安装包目录
cd nginx-1.14.2
编译
./configure --prefix=/usr/local/nginx
在新装的centos7上面安装nginx到时候，执行./config 时候 出现错误。

解决
执行下面命令解决问题
yum -y install gcc gcc-c++ autoconf automake make
编译安装nginx需要pcre包，未安装会有如下提示：
./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.
需要安装pcre的devel包，pcre-devel。使用yum安装即可：（以下命令还带有ssl、zlib等依赖的安装）
yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
OpenSSL library is not used
需要安装openssl包
yum install openssl*
编译并安装
make&make install
