wget http://nginx.org/download/nginx-1.25.4.tar.gz

tar -zxvf nginx-1.25.4.tar.gz

cd nginx-1.25.4

sudo dnf install pcre pcre-devel

./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-pcre

make 
make install

1.25.4的版本大于1.9.9别搞反了

1.9.9后面的版本居然不是2.起
1.9.9的openssl只支持1.0,到3.0会报错
make[1]: [objs/Makefile:775：objs/src/event/ngx_event_openssl.o] 错误 1 make[1]: 离开目录“/root/nginx-1.9.9” make: [Makefile:8：build] 错误 2

还有下面这一堆错误都是这个引起的

make问题1：make的时候报错：

出现这个问题一般不是Nginx的版本高就是服务器版本高的问题

vim objs/Makefile

-Werror: gcc将所有的警告当成错误进行处理把这行内容中的 “-Werror”去掉

make问题2：

src/os/unix/ngx_process.c: In function ‘ngx_signal_handler’:
src/os/unix/ngx_process.c:407:28: warning: this statement may fall through [-Wimplicit-fallthrough=]
ngx_debug_quit = 1;

    -o objs/src/os/unix/ngx_daemon.o \
    src/os/unix/ngx_daemon.c

 解决办法是将vim ./src/os/unix/ngx_user.c，第36行注释， 

 /*cd.current_salt[0] = ~salt[0];*/

cc1：所有的警告都被当作是错误
所以其实是可以忽略这些警告的.

 make install
