windows如何彻底删除nginx windows彻底卸载nginx

前言

在开局配置Nginx时有可能会配置错误,报各种错误代码。看不懂或者懒得去看这个报错时,其实最简单的方式是卸载并重装咯。今天就带大家一起学习下,如何彻底卸载nginx程序。

一、卸载NGINX

卸载nginx程序的详细步骤

1、停止Nginx软件

/usr/local/nginx/sbin/nginx -s stop

如果不知道nginx安装路径,可以通过执行ps命令找到nginx程序的PID,然后kill其PID

2、查找根下所有名字包含nginx的文件

sudo find / -name nginx*

3、执行命令删除nignx安装的相关文件

说明:全局查找往往会查出很多相关文件,但是前缀基本都是相同,后面不同的部分可以用*代替,以便快速删除~

[root@qll251 ~]# rm -rf /usr/local/sbin/nginx
[root@qll251 ~]# rm -rf /usr/local/nginx
[root@qll251 ~]# rm -rf /usr/src/nginx-1.11.1
[root@qll251 ~]# rm -rf /usr/local/nginx*

4、其他设置

如果设置了Nginx开机自启动的话,可能还需要下面两步

chkconfig nginx off
rm -rf /etc/init.d/nginx

5、卸载nginx依赖

yum remove nginx

删除之后,便可重新安装nginx了

二、开始安装NGINX

安装所需插件

1、安装gcc

gcc是linux下的编译器在此不多做解释,感兴趣的小伙伴可以去查一下相关资料,它可以编译 C,C++,Ada,Object C和Java等语言

命令:查看gcc版本

gcc -v

一般阿里云的centOS7里面是都有的,没有安装的话会提示命令找不到,

安装命令:

yum -y install gcc

2、pcre、pcre-devel安装

pcre是一个perl库,包括perl兼容的正则表达式库,nginx的http模块使用pcre来解析正则表达式,所以需要安装pcre库。

安装命令:

yum install -y pcre pcre-devel

3、zlib安装

zlib库提供了很多种压缩和解压缩方式nginx使用zlib对http包的内容进行gzip,所以需要安装

安装命令:

yum install -y zlib zlib-devel

4、安装openssl

openssl是web安全通信的基石,没有openssl,可以说我们的信息都是在裸奔。。。。。。

安装命令:

yum install -y openssl openssl-devel

安装nginx

1、下载nginx安装包

wget http://nginx.org/download/nginx-1.9.9.tar.gz

2、把压缩包解压到usr/local/java

tar -zxvf  nginx-1.9.9.tar.gz

3、切换到cd /usr/local/java/nginx-1.9.9/下面

执行三个命令:

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make
make install

4、切换到/usr/local/nginx安装目录

5、配置nginx的配置文件nginx.conf文件,主要也就是端口

        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
 
}

可以按照自己服务器的端口使用情况来进行配置

ESC键,wq!强制保存并退出

6、启动nginx服务

切换目录到/usr/local/nginx/sbin下面

启动nginx命令:

./nginx

指定配置文件启动
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
重启 
/usr/local/nginx/sbin/nginx -s reload -c /usr/local/nginx/conf/nginx.conf

7、访问你的服务器IP

显示

说明安装和配置都没问题OK了

8、nginx常用命令

1.启动nginx命令:./nginx 
2.重启nginx命令:./nginx -s reload
3.停止nginx命令:./nginx -s stop  
	或 ./nginx -s quit
	优雅关闭(不接受新的连接请求,等待旧的连接请求处理完毕再关闭):nginx -s quit 或者 kill -QUIT 主进程号
4.关闭nginx进程:
	ps -ef|grep nginx
	kill -9 8725 (进程号 上面的)   则关闭nginx
