升级 Apache Tomcat的办法

1、下载最新的7系列tomcat

cd /usr/local/software

wget https://www-us.apache.org/dist/tomcat/tomcat-7/v7.0.92/bin/apache-tomcat-7.0.92.tar.gz

tar -zxvf apache-tomcat-7.0.92.tar.gz

2、

rm -rf /usr/local/tomcat7_old

mv /usr/local/tomcat7 /usr/local/tomcat7_old

mv apache-tomcat-7.0.92 /usr/local/tomcat7

cd /usr/local/tomcat7/bin/

#追加文本行
sed -i -e '/#!\/bin\/sh/a\export CATALINA_HOME=\/usr\/local\/tomcat7' /usr/local/tomcat7/bin/catalina.sh
sed -i -e '/#!\/bin\/sh/a\export TOMCAT_HOME=\/usr\/local\/tomcat7' /usr/local/tomcat7/bin/catalina.sh
sed -i -e '/#!\/bin\/sh/a\JAVA_HOME=\/usr\/java\/jdk1.7.0_80' /usr/local/tomcat7/bin/catalina.sh
sed -i -e '/# OS specific support.  $var _must_ be set to either true or false./a\JAVA_OPTS="-Xms1024m -Xmx2048m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=1024m"' /usr/local/tomcat7/bin/catalina.sh
sed -i -e 's/redirectPort=\"8443\"/redirectPort=\"8443\" URIEncoding=\"UTF-8\"/g'  /usr/local/tomcat7/conf/server.xml

cd /usr/local/tomcat7/bin/   
chmod +x *.*

# 删除系统自带的小猫和例子
cd /usr/local/tomcat7/webapps
rm -rf  host-manager
rm -rf examples
rm -rf manager/
rm -rf docs

 

3、移动旧的项目回来

cd /usr/local/tomcat7_old

cd webapps

将这个目录下的所有子目录移动到 /usr/local/tomcat7下。

 

4、重新启动tomcat即可
