mvn clean install # maven packaging, successful execution will generate the target folder, which has jar files

Generate a target folder under the zkui folder after execution

cp config.cfg target/  #Copy the config.cfg file to the target folder

sudo vim target/config.cfg　＃modify config.cfg file

# Find and modify the following configuration
# zkui web page access port 
serverPort=9090
# IP Address and Port of zookeeper Cluster
zkServer=localhost:2181,localhost:2182
# Set the username and password for login zkui, where we set the username and password to admin
userSet = {"users": [{ "username":"admin" , "password":"admin","role": "ADMIN" },{ "username":"appconfig" , "password":"appconfig","role": "USER" }]}
