3.1.7. 防止 geth 异常退出

在同步主网的过程中，我们发现经常出现geth崩溃退出，为了防止异常退出，我们写了这个脚本。

		
[ethereum@netkiller ~]$ cat run.sh 
#!/bin/bash
for (( ; ; ))
do
	#geth --syncmode light --cache 2048 --maxpeers 200
	# geth --syncmode light --cache 2048 --maxpeers 200 --rpc --rpcaddr 0.0.0.0 --rpcport 7545 --rpcapi web3,admin,eth,personal --port 30303 2> /tmp/geth.log
	geth --datadir private --networkid 44444 --port 30302 --mine --rpc
	#geth --testnet --syncmode light --cache 2048 --maxpeers 200 --rpc 2> /tmp/geth.log
	sleep 10
