这篇文章给大家分享的是有关Redis如何修改redis-trib.rb使其import支持密码的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
需求，现在需要将一个单机redis数据迁移至redis-cluster集群中，两遍都是开启了密码模式的，无密码模式直接import就可以了！现在带密码我试了下import工具发现并不支持密码模式，修改下redis-trib.rb脚本即可支持密码认证了
target端如何支持密码上篇博客已经说明
以下修改为支持source端（单节点端）
修改地方为：
def import_cluster_cmd(argv,opt)
source_addr = opt['from']
xputs ">>> Importing data from #{source_addr} to cluster #{argv[1]}"
use_copy = opt['copy']
use_replace = opt['replace']
#use_password = opt['password'] 这行注释
# Check the existing cluster.
load_cluster_info_from_node(argv[0])
check_cluster
# Connect to the source node.
xputs ">>> Connecting to the source Redis instance"
src_host,src_port,use_password = source_addr.split(":") ##这行修改添加密码
source = Redis.new(:host =>src_host, :port =>src_port, :password =>use_password) ##这行使用如下：
[root@ip-172-31-40-224 src]# /usr/local/src/redis-4.0.8/src/redis-trib.rb import --from 172.31.40.224:6381:inH7HkD7iXoxKZCi --copy 172.31.40.224:6379
