安装Memcached
[root@nginx ~]# yum -y install libevent memcached
[root@nginx ~]# yum -y install libevent memcached
User information such as the size specified, the working environment often designated size is typically 4 to 8G, the test using this information.
[root @ nginx ~] # memcached -u root -m 120M -n 10 -f 2 -d -vvv -c 120
[root @ nginx ~] # memcached -u root -m 120M -n 10 -f 2 -d -vvv -c 120
Some of the options mean:
-h # view help
-p # specify the port number memcached is listening, 11211 default
user identity using the -l #memcached program is running must be root
-m # specify how much physical memory of the machine access the default data 64M
-c #memcached service maximum number of connections
-vvv # display detailed information about
the minimum space -n #chunk size of the unit is the number of bytes
-f #chunk size increase the size of a multiple of 1.25 times the default
-d # started in the background,
-h # view help
-p # specify the port number memcached is listening, 11211 default

Then create a session folder into which the corresponding jar package into them, and the version of tomcat
Then restart the tomcat service, then test access. If you refresh the Tomcat server change occurs, sessionID does not change is successful Redis Session servers difference of Redis and Memcached
* Memory utilization: simply use the key-value (key-value pairs) are stored, then Memcached higher memory utilization, if employed Redis do hash key-value store configuration, due to its modular compression, which use the memory rate will be higher than Memcached.
* Performance Comparison: Since only Redis mononuclear, polynuclear and may be used Memcached, the average Redis on each of the cores is higher than Memcached performance when small data storage. In the above 100k data, Memcached performance than Redis, although Redis also recently optimize storage performance on large data, but compared to Memcached, or slightly less.
* Redis supports data persistence, data in memory can be kept on disk, restart time can be used again to load
* Redis supports backup data, namely data backup master-slave mode.
* Redis not only support simple key-Value type data, while also providing a storage list, set, zset, hash data structure like
