#source /etc/bashrc
查看版本 [root@r6-3 ~]# java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mod
4、安装tomcat
#tar zxf apache-tomcat-7.0.47.tar.gz
#mv apache-tomcat-7.0.47 /usr/local/tomcat
#cd /usr/local/tomcat/bin/
5、启动tomcat服务
[root@r6-3 bin]# ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.7.0_45/
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
1、查看启动
[root@r6-3 bin]# ps -elf | grep tomcat
0 S root 5580 1 3 80 0 - 239083 futex_ 10:27 pts/0 00:00:03 /usr/java/jdk1.7.0_45//bin/java - Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/tomcat/endorsed -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
0 S root 5602 3308 0 80 0 - 25811 pipe_w 10:29 pts/0 00:00:00 grep tomcat
[root@r6-3 bin]# lsof -i :8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 5580 root 42u IPv6 22002 0t0 TCP *:webcache (LISTEN)
#elinks http://192.168.122.30:8080
2、修改默认端口
#vim /usr/loacl/tomcat/conf/server.xml
<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
3、重启 ./shutdown.sh && ./startup.sh
4、192.168.122.20重复上述配置
==============三、memcached 部分=================
一、材料
1、libevent-2.0.15-stable.tar.gz
2、memcached-1.4.5.tar.gz
二、安装配置
1、安装libevent
[root@localhost tmp]# tar xf libevent-2.0.15-stable.tar.gz
[root@localhost tmp]# cd libevent-2.0.15-stable
[root@localhost libevent-2.0.15-stable]# ./configure && make && make install
2、安装memcached
[root@localhost tmp]# tar xf memcached-1.4.5.tar.gz
[root@localhost tmp]# cd memcached-1.4.5
[root@localhost memcached-1.4.5]# ./configure && make && make install
[root@localhost memcached-1.4.5]# memcached -h #r6可能需要cp /usr/local/lib/libevent-2.0.so.5 /lib64/这步
[root@localhost memcached-1.4.5]# memcached -p 11211 -l 192.168.122.40 -u root -m 10 -c 10 -vvv -f 1.2 -n 60
telnet测试memcached
#telnet 192.168.122.40 11211
Trying 192.168.122.40...
Connected to 192.168.122.40.
Escape character is '^]'.
set key0 0 180 3 #设置key
123 #设置key 的value
STORED
get key0 #获取key0的值
VALUE key0 0 3
123
END
注意：set key1 0 3600 3
key1表示key的名字
0表示一个跟该key有关的自定义数据
3600表示该key的有效时间
3表示key1值的字节数
3、192.168.122.50重复上述配置
==============四、配置tomcat支持连接Memcached================

二、配置
#vim /usr/local/tomcat/conf/context.xml
在<Context></Context>中加入
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:192.168.122.40:11211,n2:192.168.122.50:11211"
failoverNodes="n1"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
三、重启tomcat服务
#echo "关闭tomcat" && /usr/local/tomcat/bin/shutdown.sh && echo "启动tomcat" && /usr/local/tomcat/bin/startup.sh
===============备注===============
memcached常用设置：
-p <num> 监听的端口
-l <ip_addr> 连接的IP地址, 默认是本机
-d start 启动memcached服务
-d restart 重起memcached服务
-d stop|shutdown 关闭正在运行的memcached服务
-d install 安装memcached服务
-d uninstall 卸载memcached服务
-u <username> 以<username>的身份运行 (仅在以root运行的时候有效)
-m <num> 最大内存使用，单位MB。默认64MB
-M 内存耗尽时返回错误，而不是删除项
-c <num> 最大同时连接数，默认是1024
-f <factor> 块大小增长因子，默认是1.25
-n <bytes> 最小分配空间，key+value+flags默认是48
-h 显示帮助
