方法一安装
apt市场直接安装，版本号是1.14.0，会自动安装启动脚本、系统命令脚本
sudo apt-get install nginx
sudo nginx -v
sudo systemctl status nginx
liguangming@ubuntu:~$ sudo apt-get install nginx

将会同时安装下列软件：
libnginx-mod-http-geoip libnginx-mod-http-image-filter libnginx-mod-http-xslt-filter
libnginx-mod-mail libnginx-mod-stream nginx-common nginx-core
...

liguangming@ubuntu:~$ sudo nginx -v
nginx version: nginx/1.14.0 (Ubuntu)

方式一卸载
# 卸载安装包
sudo apt-get uninstall nginx
# 删除系统命令
sudo rm -rf /lib/systemd/nginx.service
# 删除启动脚本
sudo rm -rf /etc/init.d/nginx
# 删除所有可执行文件及配置文件
sudo rm -rf /usr/sbin/nginx /usr/lib/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz
方式二 在线下载依赖+离线编译安装
方式二安装
下载链接如下，找最新版即可，我目前的版本是1.25.1，下载获得文件：nginx-1.25.1.tar.gz，这个版本不会自动安装启动脚本，也不会添加系统命令脚本
https://nginx.org/en/download.html\
# 放在一个临时目录后，开始解压缩安装
cp nginx-1.25.1.tar.gz ~/Downloads/nginx-installer/
cd ~/Downloads/nginx-installer/
tar -zxvf nginx-1.25.1.tar.gz
cd nginx-1.25.1
# 安装依赖
sudo apt-get install build-essential
sudo apt-get install libpcre3-dev zlib1g-dev libssl-dev
# 编译环境检查及编译准备
./configure
# 编译并安装
sudo make install
# 找到安装目录
cd /usr/local/nginx/sbin/
# 查看版本
./nginx -v
方式二卸载
sudo rm -rf /usr/local/nginx
方式三 离线编译安装
参考官网方式，下载一个sh文件后，执行，下载好对应的压缩包文件，放入宿主机，就可以安装了。
