旧节点： 升级前注意备份data/l2_execution_engine_data文件夹 停止节点，执行docker compose stop或者down再更新
1.在main分支执行git pull或者以其他方式更新下载仓库https://github.com/MXCzkEVM/simple-mxc-node 2.复制.env.exmaple文件更名为.env，并且修改L1_ENDPOINT_HTTP,L1_ENDPOINT_WS环境变量分别为arbitrum one网络的http rpc和rpc websocket链接
执行"docker compose --profile l2_execution_engine up -d"命令
Old Node: Before upgrading, remember to back up the data/l2_execution_engine_data folder. Stop the node by running docker compose stop or down, then proceed with updates.
Steps:
On the main branch, run git pull or update the repository via other methods: https://github.com/MXCzkEVM/simple-mxc-node. Copy the .env.exmaple file and rename it to .env. Set L1_ENDPOINT_HTTP and L1_ENDPOINT_WS to the HTTP RPC and WebSocket RPC endpoints of the Arbitrum One network, respectively. Run the "docker compose --profile l2_execution_engine up -d"command.
