Nginx安装
nginx-1.10.1.tar.gz安装,参考http://blog.csdn.net/tototuzuoquan/article/details/47381907。
修改nginx.conf的配置文件

proxy_temp_path /data/tpl_nginx_cache_dir/temp;
##设置缓存目录为二级目录,共享内存区大小,非活动时间,最大容量,注意临时目录要跟缓存目录在同一个分区

Redis安装
redis-3.2.6.tar.gz安装,参考方式:
用源码工程来编译安装
1、 到官网下载最新stable版,这里使用的是: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、解压源码并进入目录cd /usr/local/redis-src/redis-3.2.6
3、 先执行make,检查是否报错
如果报错提示缺少gcc,则安装gcc : yum install -y gcc
如果报错提示:Newer version ofjemalloc required
则在make时加参数:make MALLOC=libc (如果没有报错,直接使用make命令)
4、安装redis,指定安装目录,如 /usr/local/redis
make PREFIX=/usr/local/redis install
5、拷贝一份配置文件到安装目录下
切换到源码目录,里面有一份配置文件redis.conf,然后将其拷贝到安装路径下
cp redis.conf /usr/local/redis/
6、启动redis
cd /usr/local/redis
bin/redis-server redis.conf (如果想后台进程运行,修改:daemonize yes)
vim redis.conf 将下面的变量修改为:
daemonize yes
将bind的id换成真实的ip地址,比如:
bind 192.168.1.1
在集群配置中,要对redis配置密码,修改的配置是将redis.conf这个文件的下面的变量配置成如下的:
requirepass cloudTplWebapp (这里设置一个密码:cloudTplWebapp)
7、连接redis
另开一个xshell,然后:
#cd /usr/local/redis/
[root@hadoop redis]# bin/redis-cli
127.0.0.1:6379>
tomcat-redis-session-manager开源项目的使用
1、开源项目地址:https://github.com/jcoleman/tomcat-redis-session-manager
2、下载代码之后需要进行重新编译,生成所需要的jar,任意创建maven项目,将src下的代码拷贝到具体位置,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、然后打开terminal,执行mvn clean 和mvn install 将编译好的代码打包为:tomcat-redis-session-1.0-SNAPSHOT.jar
4、将tomcat-redis-session-1.0-SNAPSHOT.jar、jedis-2.7.3.jar、commons-pool2-2.3.jar三个jar包分别放在tomcat1和tomcat2实例下的lib目录下。
图 32 jar包所在位置
5、修改tomcat实例下conf/contex.xml文件
<?xml version='1.0' encoding='utf-8'?>

tomcat-redis-session共享配置,下面的host表示的是redis的ip地址。
port:表示的意思是redis的端口。
password:表示的意思是redis的password (这里就是5.2.2中Redis配置的password的值,如果不配置密码
database:选择的redis的db是0)

</Context>
分别修改:/data/tomcat1/bin和 /data/tomcat2/bin 下的catalina.sh,修改JVM参数信息和指定JDK
export "JAVA_OPTS=-Xms512m -Xmx1024m -XXermSize=256M -XX:MaxNewSize=256m -XX:MaxPermSize=1024m"
export "JAVA_HOME=/data/jdk8-for-tomcat7/jdk1.8.0_121"
最后,重启一下tomcat。
