参考2018-11-22 Debug以太坊go-ethereum实战
这个在windows上调试挺方便的,但是放到ubuntu上死活debug出错,goland到底存在啥问题呢,实在找不到原因,就想到一个折中的方法来解决:使用goland启动go-ethereum,然后使用dlv调试,方法如下:
1、用su修改文件,然后重启
使用dlv attach的时候回出现类似下面的错误
Could not attach to process. If your uid matches the uid of the target process
需要修改文件/etc/sysctl.d/10-ptrace.conf,将此文件下的kernel.yama.ptrace_scope = 1 改为0, 允许普通用户调试。但必须重启生效。
2、goland启动go-ethereum
参考2018-11-22 Debug以太坊go-ethereum实战配置,然后启动,当然如果选择debug一定退出
3、使用dlv调试
启动一个终端,执行ps
ps aux | grep geth
elikong 2504 0.9 4.8 960080 194284 pts/0 Sl+ 10:58 0:00 /tmp/___go_build_github_com_ethereum_go_ethereum_cmd_geth --datadir /home/elikong/temp/geth-data0 --networkid 1314 --nodiscover --rpcport 6001 --port 30001 --ipcpath /home/elikong/temp/geth-data0/geth1.ipc console
elikong 2543 0.0 0.0 21536 1036 pts/1 S+ 10:59 0:00 grep --color=auto geth
然后使用dlv
dlv attach 2504

(dlv) c
然后回到goland的run窗口里面输入
personal.unlockAccount(eth.accounts[0])
eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[1],value:web3.toWei(10,"ether")})
回车后,返回到dlv的终端,这个时候看到断点断下来了,剩下的就是参考使用Delve进行Golang代码的调试进行代码调试了
