修改java_home

vim /etc/profile
export JAVA_HOME=/data/java export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar export JAVA_HOME JAVA_BIN PATH CLASSPATHLD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib export LD_LIBRARY_PATH

安裝openssl

yum install -y zlib tar zxf openssl-1.0.2h.tar.gz cd openssl-1.0.2h ./config shared zlib make make install
mv /usr/bin/openssl /usr/bin/openssl.bak mv /usr/include/openssl /usr/include/openssl.bak ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl ln -s /usr/local/ssl/include/openssl /usr/include/openssl echo “/usr/local/ssl/lib” >> /etc/ld.so.conf ldconfig -vopenssl version -a ?

安裝apr

tar -xvf apr-1.5.2.tar.gz cd apr-1.5.2 ./configure --prefix=/usr/local/apr make make install

安裝apr-iconv

tar -xvf apr-iconv-1.2.1.tar.gz cd apr-iconv-1.2.1 ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr make make install

安裝apr-util

tar zxvf apr-util-1.5.4.tar.gz cd apr-util-1.5.4 ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr make make install cd /root

增加tomcat項目

tar zxvf apache-tomcat-7.0.61.tar.gz mv apache-tomcat-7.0.61 你項目的路徑和名字

cd /你項目的路徑和名字/bin

tar zxvf tomcat-native.tar.gz
cd tomcat-native-1.1.33-src/jni/native/
./configure --with-apr=/usr/local/apr
make
make install

參考定義java回收

vim 你項目的路徑和名字/bin/catalina.sh　 JAVA_OPTS="-server -Xms2048m -Xmx2048m -XX:PermSize=256M -XX:MaxPermSize=512m -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:MaxGCPauseMillis=50 -XX:GCPauseIntervalMillis=200"

參考定義不用端口直接訪問tomcat

<Connector port="8999"
protocol="org.apache.coyote.http11.Http11AprProtocol"
executor="tomcatThreadPool"
compression="on"
compressionMinSize="2048"
maxThreads="30000"
minSpareThreads="50"
maxSpareThreads="200"
enableLookups="false"
redirectPort="8444"
acceptCount="35000"
debug="0"
connectionTimeout="40000"
disableUploadTimeout="true" URIEncoding="UTF-8" useBodyEncodingForURI="true" />
<!-- A "Connector" using the shared thread pool-->

在<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">下面增加 <Context path="" docBase="你項目的路徑和名字" />

1.配置Tomcat的conf目錄下的context.xml文件：

1> 單點Reids配置

vim context.xml
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" /> <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" host="IP" port="端口" database="用的你個redis數據庫，默認16個，自己指定" maxInactiveInterval="60"/>

2> Sentinel集群配置：

<!-- Sentinel 配置 --> <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" /> <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" maxInactiveInterval="60" sentinelMaster="mymaster" sentinels="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381,127.0.0.1:26382" />

復制commons-logging-1.2.jar?commons-pool2-2.4.1.jar?jedis-2.5.2.jar?tomcat-redis-session-manage-tomcat7.jar到你tomcat的lib目錄下

啟動tomcat，看日志提示?Will expire sessions after 1800 seconds
