1.pcre问题

 In file included fromsrc/core/ngx_core.h:72:0,
                 from src/core/nginx.c:9:
src/core/ngx_regex.h:15:18: fatal error:pcre.h: No such file or directory
 #include <pcre.h>

 解决方案:

yum installpcre-devel

这个是重写模块必须的

当时只安装了pcre库，没安装pcre-devel 

2.openssl版本错误

       -oobjs/src/event/ngx_event_openssl.o \
       src/event/ngx_event_openssl.c

make[1]: Leaving directory`/usr/local/nginx'
make: *** [build] Error 2

解决方案

The OpenSSL API has changed quite a bit in 1.1.0... thismeans that nginx needs some work to adapt. I recommend you talk with the nginxfolks.

替换openssl的包为1.0.1的版本

3.pcre版本错误

cd /home/webrtc/live/pcre \
&& make libpcre.la
make[2]: Entering directory`/home/webrtc/live/pcre'
make[2]: *** No rule to make target `libpcre.la'.  Stop.
make[2]: Leaving directory`/home/webrtc/live/pcre'
make[1]: ***[/home/webrtc/live/pcre/.libs/libpcre.a] Error 2
make[1]: Leaving directory`/usr/local/nginx'
make: *** [build] Error 2

解决方案：

pcre2-10.20.tar.gz

切换到pcre-8.39.tar.bz2版本

4.make install错误

[root@localhost nginx]# make install
make -f objs/Makefile install
make[1]: Entering directory`/usr/local/nginx'
test -d '/usr/local/nginx' || mkdir -p'/usr/local/nginx'

test ! -f '/usr/local/nginx/sbin/nginx' \
       ||mv '/usr/local/nginx/sbin/nginx' \
              '/usr/local/nginx/sbin/nginx.old'
cp objs/nginx '/usr/local/nginx/sbin/nginx'

       ||mkdir -p '/usr/local/nginx/conf'
cp conf/koi-win '/usr/local/nginx/conf'
cp: ‘conf/koi-win’ and‘/usr/local/nginx/conf/koi-win’ are the same file
make[1]: *** [install] Error 1
make[1]: Leaving directory`/usr/local/nginx'
make: *** [install] Error 2
[root@localhost nginx]# mv /usr/local/nginx
mv: missing destination file operand after‘/usr/local/nginx’
Try 'mv --help' for more information.

解决方案：

nginx源码包目录和安装目录(配置的)，产生了冲突

把nginx源码包从/usr/local/nginx  拷贝到/home/username/nginx

重新make install

5.nginx reload出错

[root@localhost sbin]# ./nginx -s reload
nginx: [error] open()"/usr/local/nginx/logs/nginx.pid" failed (2: No such file ordirectory)

解决方案

[root@localhostsbin]# ./nginx -c /usr/local/nginx/conf/nginx.conf

//查看文件是否存在

[root@localhostsbin]# ls /usr/local/nginx/logs/
access.log  error.log nginx.pid

使用nginx -c的参数指定nginx.conf文件的位置
