For example, the installation directory:/opt/zhiqingyun

Back up data

cd /opt/zhiqingyun
# 压缩数据
tar -czvf resources.tar.gz resources
tar -czvf resources_bak.tar.gz resources_bak
# 下载数据
scp root@127.0.0.1:/opt/zhiqingyun/resources.tar.gz ~/Downloads/
scp root@127.0.0.1:/opt/zhiqingyun/resources_bak.tar.gz ~/Downloads/

Back up project configuration files

scp root@127.0.0.1:/root/application-local.yml ~/Downloads/

backup ssl certificate

scp root@127.0.0.1:/root/zhiqingyun-demo.isxcode.com.key ~/Downloads/
scp root@127.0.0.1:/root/zhiqingyun-demo.isxcode.com.pem ~/Downloads/
scp root@127.0.0.1:/root/zhiqingyun.isxcode.com.key ~/Downloads/
scp root@127.0.0.1:/root/zhiqingyun.isxcode.com.pem ~/Downloads/

Back up NGINX configuration files

scp root@127.0.0.1:/etc/nginx/nginx.conf ~/Downloads/

New Server - Installing NGINX Offline

scp /Users/ispong/OneDrive/Downloads/linux/nginx/nginx-1.26.2-1.el8.ngx.x86_64.rpm root@127.0.0.1:/tmp
cd /tmp
rpm -ivh nginx-1.26.2-1.el8.ngx.x86_64.rpm
rm -f /tmp/nginx-1.26.2-1.el8.ngx.x86_64.rpm
nginx

Move files

mkdir -p /data/nginx/ssl/
cp /root/zhiqingyun-demo.isxcode.com.pem /data/nginx/ssl/
cp /root/zhiqingyun-demo.isxcode.com.key /data/nginx/ssl/
cp /root/zhiqingyun.isxcode.com.pem /data/nginx/ssl/
cp /root/zhiqingyun.isxcode.com.key /data/nginx/ssl/

mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf_bak
mv /root/nginx.conf /etc/nginx/nginx.conf

mkdir -p /opt/zhiqingyun
mkdir -p /opt/zhiqingyun/resources_bak
tar -vzxf /root/resources.tar.gz -C /opt/zhiqingyun
rm -f /root/resources.tar.gz

Fix NGINX.pid

ps -C nginx -o pid= | head -n 1 | awk '{print $1}' > /run/nginx.pid
cat /run/nginx.pid
