# 2、修改 data 文件地址(可选)
mkdir -p /usr/local/zookeeper/data
#注释掉原有的配置
sed "s/^dataDir=.*/#&/" /usr/local/zookeeper/conf/zoo.cfg -i
#加入新配置
grep -q '^#dataDir=' /usr/local/zookeeper/conf/zoo.cfg && sed -i '/^#dataDir=.*/a\dataDir=/usr/local/zookeeper/data' /usr/local/zookeeper/conf/zoo.cfg || echo 'dataDir=/usr/local/zookeeper/data' >> /usr/local/zookeeper/conf/zoo.cfg
