Redis安裝
redis-3.2.6.tar.gz安裝，參考方式：
| 用源碼工程來編譯安裝 1、? 到官網(wǎng)下載最新stable版，這里使用的是：redis-3.2.6.tar.gz 2、? cd /usr/local ? 3、? make redis-src 4、? tar -zxvf ? ?redis-3.2.6.tar.gz? -C? ./redis-src/ 2、解壓源碼并進入目錄cd ?/usr/local/redis-src/redis-3.2.6 3、?先執(zhí)行make，檢查是否報錯 如果報錯提示缺少gcc，則安裝gcc ：? yum install -y gcc 如果報錯提示：Newer version ofjemalloc required 則在make時加參數(shù)：make MALLOC=libc （如果沒有報錯，直接使用make命令） ? 4、安裝redis，指定安裝目錄,如 /usr/local/redis make PREFIX=/usr/local/redis install ? 5、拷貝一份配置文件到安裝目錄下 切換到源碼目錄，里面有一份配置文件redis.conf，然后將其拷貝到安裝路徑下 cp redis.conf /usr/local/redis/ ? 6、啟動redis cd /usr/local/redis bin/redis-server redis.conf ? （如果想后臺進程運行，修改：daemonize yes） ? vim redis.conf 將下面的變量修改為： daemonize yes ? 將bind的id換成真實的ip地址，比如： bind 192.168.1.1 ? 在集群配置中，要對redis配置密碼，修改的配置是將redis.conf這個文件的下面的變量配置成如下的： requirepass cloudTplWebapp??? （這里設(shè)置一個密碼：cloudTplWebapp） 7、連接redis 另開一個xshell，然后： #cd /usr/local/redis/ [root@hadoop redis]# bin/redis-cli? 127.0.0.1:6379> |

tomcat-redis-session-manager開源項目的使用
1、開源項目地址：https://github.com/jcoleman/tomcat-redis-session-manager
2、下載代碼之后需要進行重新編譯，生成所需要的jar，任意創(chuàng)建maven項目，將src下的代碼拷貝到具體位置，如下：
maven的pom.xml文件如下：
| <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" ???????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ???????? xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> ??? <modelVersion>4.0.0</modelVersion> ? ??? <groupId>com.ufind.session</groupId> ??? <artifactId>tomcat-redis-session</artifactId> ??? <version>1.0-SNAPSHOT</version> ? ??? <dependencies> ??????? <dependency> ??????????? <groupId>org.apache.tomcat</groupId> ??????????? <artifactId>tomcat-catalina</artifactId> ??????????? <version>7.0.27</version> ??????? </dependency> ??????? <dependency> ??????????? <groupId>redis.clients</groupId> ??????????? <artifactId>jedis</artifactId> ??????????? <version>2.7.2</version> ??????? </dependency> ??? </dependencies> ? ??? <build> ??????? <plugins> ??????????? <plugin> ??????????????? <groupId>org.apache.maven.plugins</groupId> ??????????????? <artifactId>maven-compiler-plugin</artifactId> ??????????????? <version>3.0</version> ??????????? ????<configuration> ??????????????????? <source>1.7</source> ??????????????????? <target>1.7</target> ??????????????????? <encoding>UTF-8</encoding> ??????????????? </configuration> ??????????? </plugin> ??????? </plugins> ??? </build> ? </project> |
?
3、然后打開terminal，執(zhí)行mvn clean 和mvn install 將編譯好的代碼打包為：tomcat-redis-session-1.0-SNAPSHOT.jar
4、將tomcat-redis-session-1.0-SNAPSHOT.jar、jedis-2.7.3.jar、commons-pool2-2.3.jar三個jar包分別放在tomcat1和tomcat2實例下的lib目錄下。
圖 32 jar包所在位置
5、修改tomcat實例下conf/contex.xml文件
| <?xml version='1.0' encoding='utf-8'?> <!-- ? Licensed to the Apache Software Foundation (ASF) under one or more ? contributor license agreements.?

分別修改：/data/tomcat1/bin和? /data/tomcat2/bin 下的catalina.sh,修改JVM參數(shù)信息和指定JDK
| export "JAVA_OPTS=-Xms512m -Xmx1024m -XX:PermSize=256M -XX:MaxNewSize=256m -XX:MaxPermSize=1024m" export "JAVA_HOME=/data/jdk8-for-tomcat7/jdk1.8.0_121" |
?
最后，重啟一下tomcat。
