Jedis
<p>After you create an ECS instance and a whitelist entry, install a Jedis client on the ECS instance and access the Redis instance from the Jedis client.</p>
<p><strong><span style="font-size:18px">Prerequisites</span></strong></p>
<ol>
<li>You have successfully created a Redis instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_Redis" target="_blank">Create a Redis Instance</a>. Make sure the instance is in running status.</li>
<li>You have successfully created an ECS instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_ECS" target="_blank">Create an ECS Instance</a>. Make sure the instance is in running status.</li>
<li>You have successfully created a whitelist entry. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_Whitelist" target="_blank">Create a Whitelist Entry</a>.</li>
</ol>
<p><strong><span style="font-size:18px">Procedures</span></strong></p>
<p>1. Log in to the ECS instance.</p>
<p> a. Log in to the <a href="https://pinganyun.com/console/ecs/overview" target="_blank">ECS Console</a>.</p>
<p> b. In the left navigation pane, click <strong>Instance</strong> to enter the <strong>Instance Management</strong> page.</p>
<p> c. In the <strong>Operations</strong> column for the target instance, click <strong>ECS Console</strong>.</p>
<p> d. Enter the username and password.</p>
<p>2. Download and install the Jedis client and common-pool2.</p>

<ul>
<li>You must download Jedis 2.9.0 or higher. The download address is download address.</li>
<li>You must download commons-pool2 or higher versions. The download address is download address.</li>
</ul>
<p>3. Connect to the Redis instance. Create a Project on the Eclipse client and execute the following codes:</p>
<pre>
<code>import java.util.HashSet;
import java.util.Set;
import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
public class pacloud_redis_usage
{
private static JedisCluster pool = null;
public static JedisCluster getPool() {
if (pool == null) {
GenericObjectPoolConfig = new GenericObjectPoolConfig();
genericObjectPoolConfig.setMaxIdle(50); //Maximum idle connections
genericObjectPoolConfig.setMinIdle(20); //Minimum idle connections
genericObjectPoolConfig.setMaxWaitMillis(3000L);
genericObjectPoolConfig.setMaxTotal(100); //Maximum connecttions
Set<HostAndPort> node = new HashSet<HostAndPort>();
node.add(new HostAndPort("Domain-Name ", Port)); //Specify the domain name and port number of the Redis instance
pool = new JedisCluster(node, 10000, 3000, 5, "Password", genericObjectPoolConfig);
//Specify the access password displayed in the console
}
return pool;
}
public static void main(String[] args)
throws Exception
{
JedisCluster jc = getPool();
try {
jc.set("foo", "pingan yun");
System.out.println(jc.get("foo"));
}
catch (Exception e)
{
e.printStackTrace();
}
}
}</code></pre>

<ul>
<li>Domain-Name: Access domain name of the Redis instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/User_Guide.Instance_Management.View_Instance" target="_blank">View Basic Information about an Instance</a>.</li>
<li>Port: Port number of the Redis instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/User_Guide.Instance_Management.View_Instance" target="_blank">View Basic Information about an Instance</a>.</li>
<li>Password: Password of the Redis instance that has been set when you create the Redis instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/User_Guide.Instance_Management.View_Instance" target="_blank">View Basic Information about an Instance</a>.</li>
</ul>
<p><strong><span style="font-size:18px">Result</span></strong></p>
<p>The system returns pingan yun, indicating that the Jedis client has been successfully connected to the Redis instance.</p>
