Memcache command-line Operations

Looking for a long time today, how to see the value of Memcache directly in the server, to determine whether PHP Memcache has been written in the

Https://www.ttlsa.com/memcache/memcache-list-all-keys/This method is not only applicable to windowns cmd. Also applies to Linux command line operations, the following is the specific content

Today is doing a memcache session test, but in the process of testing, found that memcache there is no relatively simple way to directly like Redis, keys * List all session key, and according to key get corresponding session content , so, I began to look for information, most of the memcache are some of the common commands, but the list of key methods, but not much, so came to Google, found a foreign material

Specific content I applied in my test environment, the operation is as follows

1. cmd on login memcache

1	> telnet 127.0.0.1 11211

2. List all keys

1234	stats Items //This is an order . STAT Items:7:number 1 STAT items:7:age 188 END

3. Get key via Itemid

Next, based on the items ID listed, this example is 7, the 2nd parameter is the length listed, and 0 is all listed

123	stats cachedump 7 0 // This is the command ITEM sess_sidsvpc1473t1np08qnkvhf6j2 [183 b 1394527347 s end

4. Get the key value via get

The stats cachedump command above lists my session key, followed by a GET command to find the corresponding session value

1234567

get sess_sidsvpc1473t1np08qnkvhf6j2 //This is an order .VALUEsess_sidsvpc1473t1np08qnkvhf6j2 1440 1 the sess_| A:5:{s:6:; S:32: " E70981FD305170C41A5632B2A24BBCAA "; S:3: "UID" s:1: " s:8: "username" ; S:5: "admin" s:9: "logintime" ; S:19: 2014-03-11 16:24:25 "; S:7: "log Inip "; S:9:"127.0.0.1";}

The above operation is directly copied, I test, no problem

1. A

　　

[Plain]View PlainCopyprint?

1. telnet localhost 200001 #登陆
2. Stats #查看状态
3. Flush_all #清理
4. Quit #退出

2. Another learning:

echo ' Flush_all ' | NC localhost 200001

3.

1. Data storage (assuming key is test,value to 12345)

　　

[Plain]View PlainCopyprint?

1. printf "set Test 0 0 5\r\n12345\r\n" | NC 127.0.0.1 200001
2. STORED

2. Data retrieval (assuming key is test)

　　

[Plain]View PlainCopyprint?

1. printf "Get test\r\n" | NC 127.0.0.1 200001
2. VALUE Test 0 5
3. 12345
4. END

3. Increase the value by 1 (assuming that key is test and value is a positive integer)

printf "incr Test 1\r\n" | NC 127.0.0.1 200001

12346

4, the value is reduced by 3 (assuming that key is test and value is a positive integer)

　

[Plain]View PlainCopyprint?

1. printf "DECR Test 3\r\n" | NC 127.0.0.1 200001
2. 12343

5. Data deletion (assuming key is test)

　　

[Plain]View PlainCopyprint?

1. printf "Delete test\r\n" | NC 127.0.0.1 11211
2. DELETED

6. View memcached Status

　

[Plain]View PlainCopyprint?

2. printf "stats\r\n" | NC 127.0.0.1 200001
4. STAT PID 3025
6. STAT Uptime 4120500

7. Simulate top command to view memcached status:

　　

[Plain]View PlainCopyprint?

1. printf "stats\r\n" | NC 127.0.0.1 200001
2. Or
3. Watch "Echo Stats | NC 127.0.0.1 200001 "
