Nginx的各种报错总结

      ./configure: error: the HTTP rewrite module requires the PCRE library.
      You can either disable the module by using --without-http_rewrite_module
      option, or install the PCRE library into the system, or build the PCRE library
      statically from the source with nginx by using --with-pcre=<path> option.

解决方法：yum install pcre pcre-devel -y

 ./configure: error: SSL modules require the OpenSSL library.
 You can either do not enable the modules, or install the OpenSSL library
 into the system, or build the OpenSSL library statically from the source
 with nginx by using --with-openssl=<path> option.

解决方法：yum install openssl openssl-devel -y

报错信息如下：
[root@gjlin2 pcre-8.30]# make && make install

解答：执行"yum -y install gcc-c++"命令安装gcc-c++依赖包。

解决方法：nginx软件已经启动无需反复启动，如果需要重新启动需要停止nginx进程或者用reload方式进行重启

[root@web tools]# pkill nginx

[root@web tools]# userdel nginx

[root@web tools]# /application/nginx/sbin/nginx

nginx: [emerg] getpwnam(Mnginx") failed

[root@web tools]# useradd nginx -s /sbin/nologin -M

[root@web tools]# /application/nginx/sbin/nginx
