[ghost]

when i run the example counter,i got some problem like "". i think it is caused by undefine conf. so how do i define the conf ? please tell me ,thank you.
DEFINE_string(conf, "", "Initial configuration of the replication group");

the error :
node Counter:127.0.0.1:8100:0 term 1 start pre_vote
W0320 16:40:10.782916 13281 /home/robin/github/braft/src/braft/node.cpp:1305] node Counter:127.0.0.1:8100:0 can't do pre_vote as it is not in 192.168.109.128:8100:0,192.168.109.128:8101:0,192.168.109.128:8102:0

Did you run counter_server via run_server.sh?

[ghost]

yes , i use the batch script run_server.sh to run the server

my steps:

1. git clone
2. use command "mkdir build && cd build && cmake .. && make" to compile the braft
3. compile the counter : cd example/counter && cmake . && make
4. run the counter:
   ./run_server.sh
   ./run_client.sh

i don't know whether there has some wrong steps or wrong parameters.

The ip via hostname -i in run_server.sh is different with the ip via butil::my_ip() in the program. To simply solve this issue, you can rewrite the IP variable in run_server.sh to '127.0.0.1' directly. The root cause is hard to figured out, more information (kernel version, linux distribution, output of `hostname -i' etc) may help to find the issue.

it's just like what you said, i can test the counter now. thank you.
