-安装JDK

-安装tomcat:  

https://tomcat.apache.org/download-90.cgi

wget  https://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.74/bin/apache-tomcat-9.0.74.zip

unzip  apache-tomcat-9.0.74.zip   && rm -rf   apache-tomcat-9.0.74.zip

cp apache-tomcat-9.0.74  /usr/local/   &&   mv  apache-tomcat-9.0.74  tomcat

chmod -R 777 /usr/local/tomcat/bin

-修改字符集

vim  /usr/local/tomcat/conf/server.xml

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"

-修改端口号

# 根据实际情况修改下面三个端口号
<!-- 关闭时使用 -->
<Server port="8005" shutdown="SHUTDOWN">
<!-- 一般应用使用 -->
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
<!-- 为AJP端口，即容器使用，如 APACHE能通过AJP协议访问Tomcat的8009端口 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

-优化性能

vim  bin/catalina.sh

-添加
JAVA_OPTS="-Xms1024m -Xmx4096m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=2048m"
