tomcat基础学习
Tomcat是Apache软件基金会维护的一个核心项目，是一个免费的开放源码的轻量级web应用服务器，作为JSP/SERVERLET容器。
一、准备：
环境：CentOS 7 VM
YUM源：对接yum源，比如：阿里的yum源，参照网上配置
二、安装

三、启动：
# 修改tomcat的端口号/usr/share/tomcat/conf/server.xml，如下： <Connector port="8090" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> [root@localhost]# service tomcat start# 启动tomcatRedirecting to /bin/systemctl start tomcat.service# 实际为使用systemctl调用/usr/lib/systemd/system/tomcat.service配置启动tomcat[root@localhost]# service tomcat status# 查看tomcat状态Redirecting to /bin/systemctl status tomcat.service● tomcat.service - Apache Tomcat Web Application Container Loaded: loaded (/usr/lib/systemd/system/tomcat.service; disabled; vendor preset: disabled) Active: active (running) since Wed 2017-10-11 20:00:36 CST; 16min ago Main PID: 28133 (java) CGroup: /system.slice/tomcat.service └─28133 /usr/lib/jvm/jre/bin/java -classpath /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar:/usr/share/java/commons-daemon.jar -Dcatalina.base=/usr/share/tomcat -Dcatal... Oct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: Oct 11, 2017 8:00:37 PM org.apache.catalina.core.StandardService startInternalOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: INFO: Starting service CatalinaOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: Oct 11, 2017 8:00:37 PM org.apache.catalina.core.StandardEngine startInternalOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: INFO: Starting Servlet Engine: Apache Tomcat/7.0.76Oct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: Oct 11, 2017 8:00:37 PM org.apache.coyote.AbstractProtocol startOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: INFO: Starting ProtocolHandler ["http-bio-8080"]Oct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: Oct 11, 2017 8:00:37 PM org.apache.coyote.AbstractProtocol startOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: INFO: Starting ProtocolHandler ["ajp-bio-8009"]Oct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: Oct 11, 2017 8:00:37 PM org.apache.catalina.startup.Catalina startOct 11 20:00:37 iZbp1679bcuj0vinyihgk0Z server[28133]: INFO: Server startup in 112 ms# 查看进程状态[root@localhost]# ps -ef | grep tomcattomcat 28133 1 0 20:00 ? 00:00:01 /usr/lib/jvm/jre/bin/java -classpath /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar:/usr/share/java/commons-daemon.jar -Dcatalina.base=/usr/share/tomcat -Dcatalina.home=/usr/share/tomcat -Djava.endorsed.dirs= -Djava.io.tmpdir=/var/cache/tomcat/temp -Djava.util.logging.config.file=/usr/share/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager org.apache.catalina.startup.Bootstrap start
可以看到，tomcat在执行过程中会对/usr/share/tomcat/下的文件进行加载，以便响应相应的请求。
四、tomcat工作空间：
从上面的进程可以看到tomcat的工作空间：
[root@localhost]# tree /usr/share/tomcat//usr/share/tomcat/├── bin# 启动脚本，该RPM中不包含catalina.sh文件│ ├── bootstrap.jar│ ├── catalina-tasks.xml│ └── tomcat-juli.jar├── conf -> /etc/tomcat# 配置，包括server.xml（主要配置），web应用缺省文件web.xml等├── lib -> /usr/share/java/tomcat# tomcat使用的lib库(jar)，会加载到tomcat的classpath中├── logs -> /var/log/tomcat# 日志├── temp -> /var/cache/tomcat/temp# 临时文件目录├── webapps -> /var/lib/tomcat/webapps# web应用└── work -> /var/cache/tomcat/work# 工作目录，将翻译的JSP以及其他放到这里
五、webapps下创建测试网页
[root@localhost app1]# pwd# webapps目录/usr/share/tomcat/webapps/app1[root@localhost app1]# cat app1.html # 新建的应用网页<html><head> <title>This is app1</title></head><body>A test for app1</body></html>
六、关闭防火墙
有时网页不能正确的打开，需要手动关闭防火墙：
[root@localhost app1]# service firewalld statusRedirecting to /bin/systemctl status firewalld.service● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2017-10-16 08:54:25 PDT; 5 days ago Main PID: 825 (firewalld) CGroup: /system.slice/firewalld.service └─825 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid Oct 16 08:54:16 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...Oct 16 08:54:25 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.[root@localhost app1]# service firewalld stopRedirecting to /bin/systemctl stop firewalld.service
七、登陆网页
