nginx卸载重装配置没变

一、nginx卸载重装前的准备工作

在进行nginx卸载重装之前，我们需要做好以下几方面的准备工作：

1. 备份网站数据：在进行任何操作之前，我们都需要确保网站的数据已经备份，以防止在卸载和重装过程中出现数据丢失的问题。

2. 停止正在运行的nginx服务：在卸载和重装nginx之前，需要先停止正在运行的nginx服务，以免影响到其他程序的正常运行，可以使用以下命令来停止nginx服务：

sudo service nginx stop

3. 检查系统依赖：在卸载和重装nginx之前，需要检查系统中是否还有其他的软件包依赖于nginx,如果有，需要先卸载这些依赖，以免在重新安装nginx时出现问题，可以使用以下命令来查看系统中的软件包依赖：

dpkg --get-selections | grep nginx

4. 下载nginx安装包：在卸载和重装nginx之前，需要先从官方网站或者其他可信的来源下载最新版本的nginx安装包，可以使用以下命令来下载nginx安装包：

wget http://nginx.org/download/nginx-1.20.1.tar.gz

二、卸载nginx

1. 删除nginx安装目录：使用以下命令来删除已经安装的nginx目录：

sudo rm -rf /usr/local/nginx

2. 删除nginx配置文件：使用以下命令来删除已经安装的nginx配置文件：

sudo rm /etc/nginx/nginx.conf

3. 删除nginx相关文件：使用以下命令来删除与nginx相关的文件：

sudo rm /usr/local/nginx/sbin/nginx*
sudo rm /usr/local/nginx/conf/nginx*

4. 删除系统服务：使用以下命令来删除已经安装的nginx系统服务：

sudo apt-get remove --purge nginx-common libnginx-mod-http-ssl-module libnginx-mod-http-v2_6-module libnginx-mod-http-v2_7-module libnginx-mod-perl-module libnginx-mod-rtmp-module libnginx-mod-udp-module libnginx-mod-utils-curl libnginx-mod-utils-java libnginx-mod-xml2-utils
sudo apt-get autoremove
sudo apt-get autoclean

三、安装并启动nginx

1. 解压安装包：使用以下命令来解压刚刚下载的nginx安装包：

tar -zxvf nginx-1.20.1.tar.gz

2. 编译并安装：进入解压后的目录，执行以下命令来编译并安装nginx:

“`
