##需要進去，點介紹協議，下載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

啟動慢修改如下：

在catalina.sh中加入這麽一行：

JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom"

打開$JAVA_PATH/jre/lib/security/java.security這個文件，找到下面的內容：

securerandom.source=file:/dev/urandom

替換成

securerandom.source=file:/dev/./urandom

想登陸管理頁面，操作如下：

conf/Catalina/localhost/下創建 manager.xml ， 填入如下內容

<Context privileged="true" antiResourceLocking="false"
         docBase="${catalina.home}/webapps/manager">
    <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
</Context>


添加用戶  conf/tomcat-users.xml 中的 <tomcat-users></tomcat-users> 標簽內添加如下代碼：


<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 還是 403 錯誤 解決辦法 允許所有IP訪問

vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml
<Context antiResourceLocking="false" privileged="true" >
     <Valve className="org.apache.catalina.valves.RemoteAddrValve"
     allow="^.*$" /> #修改這裏
</Context>
