我按照couchbase教程连接到远程couchbase服务器,但在尝试打开默认存储桶后连接超时失败.

我已经检查过我可以在我的电脑上打开couchbase服务器页面(192.xx.xx.xx:8091)

这是我的Java代码

CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
            .queryEnabled(true)
            .build();
Cluster cluster = CouchbaseCluster.create(env,"192.xx.xx.xx:8091");

Bucket bucket = cluster.openBucket("default","");
JsonObject user = JsonObject.empty()
        .put("firstname", "Walter")
        .put("lastname", "White")
        .put("job", "chemistry teacher")
        .put("age", 50);

JsonDocument doc = JsonDocument.create("walter", user);
JsonDocument response = bucket.upsert(doc);

JsonDocument walter = bucket.get("walter");
System.out.println("Found: " + walter);

cluster.disconnect();

和控制台

com.couchbase.client.core.CouchbaseCore <init>
CouchbaseEnvironment: {sslEnabled=false, sslKeystoreFile='null', sslKeystorePassword='null', queryEnabled=true, queryPort=8093, bootstrapHttpEnabled=true, bootstrapCarrierEnabled=true, bootstrapHttpDirectPort=8091, bootstrapHttpSslPort=18091, bootstrapCarrierDirectPort=11210, bootstrapCarrierSslPort=11207, ioPoolSize=4, computationPoolSize=4, responseBufferSize=16384, requestBufferSize=16384, kvServiceEndpoints=1, viewServiceEndpoints=1, queryServiceEndpoints=1, ioPool=NioEventLoopGroup, coreScheduler=CoreScheduler, eventBus=DefaultEventBus, packageNameAndVersion=couchbase-java-client/2.1.4 (git: 2.1.4), dcpEnabled=false, retryStrategy=BestEffort, maxRequestLifetime=75000, retryDelay=ExponentialDelay{growBy …

我的操作系统是 CentOS 6.6，我想知道如何通过 shell 脚本自动安装 mysql-server。

我发现有一个主题讨论了同样的问题，但它在 CentOS 6 上失败：在 ubuntu 上安装 mysql，没有密码提示

sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password your_password'
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password your_password'

错误信息是

bash: debconf-set-selections: command not found

这是我的基本脚本

#!/bin/sh
# Make sure only root can run our script
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

#password setting
root_password='abc123'

#install mysql-server
yum install mysql mysql-server 

#start service
service mysqld start

#MySQL Initial …
