wget https://nginx.org/download/nginx-1.10.3.tar.gz

安装编译工具和库

CentOS

yum group install Development Tools
yum install openssl openssl-devel zlib zlib-devel

ubuntu

apt-get install openssl libssl-dev

安装 PCRE

tar -zxf pcre-8.35.tar.gz
cd pcre-8.35
./configure
make && make install

安装 Nginx

tar -zxf nginx-1.10.3.tar.gz
mv nginx-1.10.3 /opt/nginx/
cd /opt/nginx/nginx-1.10.3
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/root/pcre-8.35
make && make install

显示版本信息则安装成功。

/usr/local/webserver/nginx/sbin/nginx -v
