二：下载Nginx版本

1.官网直接下载.tar.gz安装包，地址：nginx: download

2.使用wget命令下载

wget -c https://nginx.org/download/nginx-1.18.0.tar.gz

3.网盘下载

cd nginx-1.18.0

四：配置

1.不需要SSL

./configure --prefix=/usr/local/nginx

2.需要SSL

# 重启
/usr/local/nginx/sbin/nginx -s reload

七：代理配置

        location = /50x.html {
            root   html;
        }
    }

# 创建证书目录
cd /usr/local/nginx/conf/
mkdir cert

server {
        listen 443 ssl;
        server_name  xxx.cn www.xxx.cn;

        ssl_certificate      cert/7369597_xxx.cn.pem;
        ssl_certificate_key  cert/7369597_xxx.cn.key;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        root   /home/busapp/ui/;
        index  index.html;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;

        location = /50x.html {
            root   html;
        }
    }

八：设置开机启动

1.即在rc.local增加启动代码就可以了。

vim /etc/rc.local

增加一行 /usr/local/nginx/sbin/nginx

2.设置执行权限

chmod 755 rc.local

 到这里，nginx就安装完毕了。

九：卸载Nginx

1.卸载Nginx

yum remove nginx

2.查看Nginx是否还存在

which nginx
