cd /usr/local/srcwget http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
##需要进去，点介绍协议，下载jdk8
tar zxvf jdk-8u144-linux-x64.tar.gz
mv jdk1.8.0_144/ /usr/local/jdk8.0
vim /etc/profile
JAVA_HOME=/usr/local/jdk8.0
JAVA_BIN=/usr/local/jdk8.0/bin
PATH=$PATH:$JAVA_BIN
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
export CATALINA_BASE=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
source /etc/profile
cd /usr/local/src/
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.23/bin/apache-tomcat-8.5.23.tar.gz
tar zxvf apache-tomcat-8.5.23.tar.gz
mv apache-tomcat-8.5.23/usr/local/tomcat8.5
ln -s /usr/local/tomcat8.5/ /usr/local/tomcat
cd /usr/local/tomcat/bin/
echo "CATALINA_HOME=/usr/local/tomcat8.5/">> catalina.sh
chmod +x *.sh
./startup.sh
启动慢修改如下：
在catalina.sh中加入这么一行：
JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom"
打开$JAVA_PATH/jre/lib/security/java.security这个文件，找到下面的内容：
securerandom.source=file:/dev/urandom
替换成
securerandom.source=file:/dev/./urandom
想登陆管理页面，操作如下：
conf/Catalina/localhost/下创建 manager.xml ， 填入如下内容

<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/manager">
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
</Context>
添加用户conf/tomcat-users.xml 中的 <tomcat-users></tomcat-users> 标签内添加如下代码：
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/>
<user username="deploy" password="deploy" roles="manager-script"/>
host-manager 还是 403 错误 解决办法允许所有IP访问

vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml
<Context antiResourceLocking="false" privileged="true" >
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="^.*$" /> #修改这里
</Context>
修改成80
vim conf/server.xml
69 <Connector port="80" protocol="HTTP/1.1"
70 connectionTimeout="20000"
71 redirectPort="8443" />
修改默认网页路径
vim conf/server.xml
148 <Host name="localhost"appBase="webapps"
149 unpackWARs="true" autoDeploy="true">
164 <Context path="" docBase="/usr/local/tomcat/webapps/shyt/" debug="0"/> ###加入此行， docBase就是你要访问的路径
165 </Host>
修改默认首页文件
vim conf/web.xml
4693 <welcome-file-list>
4694 <welcome-file>index.html</welcome-file>
4695 <welcome-file>index.htm</welcome-file>
4696 <welcome-file>index.jsp</welcome-file>
4697 </welcome-file-list>
