ubuntu 安装nginx ./configure 编译出错问题

解决办法 apt install g++ ./configure: error: the HTTP rewrite module requires the PCRE library. 解决办法 apt install libpcre3 libpcre3-dev ./configure: error: SSL modules require the OpenSSL library. 解决办法 apt install openssl libssl-dev ./configure: error: the HTTP gzip module requires the zlib library. 解决办法下载zlib-1.2.8.tar.gz 解压，./configure && make && make install安装 ./configure: error: the HTTP XSLT module requires the libxml2/libxslt 解决办法 apt-get install libxml2 libxml2-dev libxslt-dev

cc1: all warnings being treated as errors
objs/Makefile:659: recipe for target 'objs/src/core/ngx_murmurhash.o' failed
make[1]: *** [objs/src/core/ngx_murmurhash.o] Error 1
make[1]: Leaving directory '/home/always/tools/nginx-1.10.3'
Makefile:8: recipe for target 'build' failed
make: *** [build] Error 2
　原因，是将警告当成了错误处理，打开./objs/Makefile，
CFLAGS =  -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g (去掉-Werror)
再重新make -j2
-Wall 表示打开gcc的所有警告
-Werror，它要求gcc将所有的警告当成错误进行处理
#\cp objs/nginx /usr/local/nginx/sbin/nginx
如果提示“cp:cannot create regular file `/usr/local/nginx/sbin/nginx': Text file busy”
建议使用如下语句cp
#cp -rfp objs/nginx /usr/local/nginx/sbin/nginx
