liunx系统安装tomcat的方法
安装tomcat前需要先安装jdk,安装jdk的方法参考我的上一篇文章:liunx系统安装jdk的方法
1、下载tomcat
下载地址:http://tomcat.apache.org/download-60.cgi
我下载的是apache-tomcat-6.0.44.zip
2、安装tomcat
将下载的压缩包apache-tomcat-6.0.44.zip放到目录/usr/tomcat下
2.1、解压命令如下:
# unzip apache-tomcat-6.0.44.zip
2.2、编辑catalina.sh文件:
# cd /usr/tomcat/apache-tomcat-6.0.44/bin
# vi catalina.sh
在catalina.sh文件追加内容如下:
CATALINA_HOME=/usr/tomcat/apache-tomcat-6.0.44/
3、启动tomcat
# chmod +x *.sh
# ./catalina.sh start
4、测试tomcat是否已正常启动
访问 http://127.0.0.1:8080/,如果正常,说明tomcat服务已正常启动
5、打开防火墙的8080端口
默认系统防火墙开放了22端口,8080端口默认是关闭的,现在我们把tomcat默认使用的8080端口打开,否则远程访问是访问不了的
编辑/etc/sysconfig/iptables 文件(红色的内容是我添加的):
# Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A RH-Firewall-1-INPUT -p 50 -j ACCEPT -A RH-Firewall-1-INPUT -p 51 -j ACCEPT -A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited COMMIT
我在CentOS6还看到另外一个版本的:
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
默认有了22的,照着原来的添加一行tomcat的端口就可以了。
编辑文件后,让防火墙策略生效:
# /etc/init.d/iptables restart
附:防火墙的相关命令
- 启动指令:service iptables start
- 重启指令:service iptables restart
- 关闭指令:service iptables stop
