Tomcat

1、设置编码

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" useBodyEncodingForURI="true" URIEncoding="UTF-8" />
maxPostSize="20971520"
IEncoding="utf-8" URIEncoding="utf-8"

maxPostSize:

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than zero. If not specified, this attribute is set to 2097152 (2 megabytes). Note that the FailedRequestFilter can be used to reject requests that exceed this limit.

2、CentOS中安装

检查java版本信息

java -version

java version “1.7.0_99”

OpenJDK Runtime Environment (rhel-2.6.5.0.el6_7-x86_64 u99-b00)

OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

如果没有则安装：

yum -y install java-1.7.0-openjdk

下载并解压缩tomcat

cd /tmp

wget http://www.us.apache.org/dist/tomcat/tomcat-7/v7.0.68/bin/apache-tomcat-7.0.68.tar.gz

http://www-us.apache.org/dist/tomcat/tomcat-8/v8.0.33/bin/apache-tomcat-8.0.33.tar.gz

(yum -y install wget)

tar xzf apache-tomcat-7.0.68.tar.gz

mv apache-tomcat-7.0.68 /usr/local/tomcat7

启动tomcat

cd /usr/local/tomcat7

./bin/startup.sh

[输出样例]

Using CATALINA_BASE: /usr/local/tomcat7

Using CATALINA_HOME: /usr/local/tomcat7

Using CATALINA_TMPDIR: /usr/local/tomcat7/temp

Using JRE_HOME: /usr

Using CLASSPATH: /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar

Tomcat started.

访问http://ip:8080

重启tomcat服务

# ./bin/shutdown.sh

# ./bin/startup.sh

防火墙开放8080端口：一

增加8080端口到防火墙配置中，执行以下操作：

[root@localhost ~]/sbin/iptables -I INPUT -p tcp –dport 8080 -j ACCEPT #开启8080端口

[root@localhost ~]/etc/rc.d/init.d/iptables save #保存配置

[root@localhost ~]/etc/rc.d/init.d/iptables restart #重启防火墙

防火墙开放8080端口：二

增加8080端口到防火墙配置中，执行以下操作：

[root@admin ~]# vi + /etc/sysconfig/iptables

增加以下代码

-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 8080 -j ACCEPT

重启防火墙

[root@admin java]# service iptables restart

3、查看tomcat日志（类windows控制台）: tomcat/logs

tail -f catalina.out

4、设置用户账户

<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="tomcat" password="tomcat" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>

5、https及二级域名配置

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="D:/tomcat.keystore" keystorePass="luodeng"
/>

<Host name="admin.luodeng.com"  appBase="E:\\JAVA\\tomcat\\axshop_admin_web"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>

<Host name="shop.luodeng.com"  appBase="E:\JAVA\tomcat\axshop_main_web"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>

127.0.0.1  admin.luodeng.com
127.0.0.1  shop.luodeng.com

6、远程调试

catalina.sh或startup.sh
linux:
declare -x CATALINA_OPTS="-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8788"
windows:
SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8788

linux打开端口命令的使用方法

nc -lp 8788 &（打开8788端口）

查看是否打开8788端口

netstat -an | grep 8788

-Xdebug启用调试模式

-Xrunjdwp:加载JVM的JPDA参考实现库

transport=dt_socket:Socket连接，可选dt_shmem 通过共享内存的方式连接到调试服务器

address=8000:调试服务器监听的端口

server=y:是否是服务器端，n为客户端

suspend=n:启动过程是否加载暂停，y为启动时暂停，方
4000
便调试启动过程
