1.下载4个压缩包：
pcre，rewrite模块要用到，下载地址：https://ftp.pcre.org/pub/pcre/
zlib，gzip模块要用到，下载地址：http://www.zlib.net/zlib-1.2….
openssl，ssl模块用到，下载地址：https://www.openssl.org/source/
nginx，下载地址：http://nginx.org/en/download….
2.将它们放到/usr/local/下

# cd /usr/local/ 
# tar -zxvf pcre-8.38.tar.gz
# cd pcre-8.38
# ./configure
# make
# make install

# cd /usr/local/
