Redis如何修改redis-trib.rb使其import支持密码

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>>> Importing data from 172.31.40.224:6381:inH7HkD7iXoxKZCi to cluster >>> Performing Cluster Check (using node 172.31.40.224:6379)M: d5a1288c289dc27c014b34a0ec8280d2d4215747 172.31.40.224:6379   slots:0-5460 (5461 slots) master   1 additional replica(s)S: 7475145029eeccdc91b8db415377888130868199 172.31.40.224:6380   slots: (0 slots) slave   replicates c78d49f041e386723fd921cea19421e34c0262b6M: c78d49f041e386723fd921cea19421e34c0262b6 172.31.40.14:6379   slots:10923-16383 (5461 slots) master   1 additional replica(s)M: 4164f6a49979952479e98ccde18e463e125dd438 172.31.35.125:6379   slots:5461-10922 (5462 slots) master   1 additional replica(s)S: 725078c24574874197707b177375ee8dbf462099 172.31.35.125:6380   slots: (0 slots) slave   replicates d5a1288c289dc27c014b34a0ec8280d2d4215747S: 5a1cbcec8b540dd5d7ce6268942386ce6e48878f 172.31.40.14:6380   slots: (0 slots) slave   replicates 4164f6a49979952479e98ccde18e463e125dd438[OK] All nodes agree about slots configuration.>>> Check for open slots...>>> Check slots coverage...[OK] All 16384 slots covered.>>> Connecting to the source Redis instance*** Importing 3 keys from DB 0Migrating chen1 to 172.31.35.125:6379: OKMigrating chen to 172.31.40.224:6379: OKMigrating chen2 to 172.31.35.125:6379: OK
