 启动etcd，以命令行和参数启动

etcd \
--logger=zap \
--name 'sht-sgmhadoopnn-01' \
--data-dir '/usr/local/etcd/data' \
--listen-client-urls 'http://0.0.0.0:2379' \
--advertise-client-urls 'http://0.0.0.0:2379' \
--listen-peer-urls 'http://0.0.0.0:2380' \
--initial-advertise-peer-urls 'http://0.0.0.0:2380'

输出log

# etcd --logger=zap --name 'sht-sgmhadoopnn-01' --data-dir '/usr/local/etcd/data' --listen-client-urls 'http://0.0.0.0:2379' --advertise-client-urls 'http://0.0.0.0:2379' --listen-peer-urls 'http://0.0.0.0:2380' --initial-advertise-peer-urls 'http://0.0.0.0:2380'
