Tomcat

Tomcat配置SSL加密
[root@localhost ~]# keytool -genkeypair -alias tomcat -keyalg RSA -keystore /usr/local/tomcat8/keystore
输入密钥库口令:
再次输入新口令:
您的名字与姓氏是什么?
[Unknown]: crushlinux
您的组织单位名称是什么?
[Unknown]: cloud
您的组织名称是什么?
[Unknown]: cloud
您所在的城市或区域名称是什么?
[Unknown]: beijing
您所在的省/市/自治区名称是什么?
[Unknown]: beijing
该单位的双字母国家/地区代码是什么?
[Unknown]: CN
CN=crushlinux, OU=cloud, O=cloud, L=beijing, ST=beijing, C=CN是否正确?
[否]: y

输入 <tomcat> 的密钥口令
(如果和密钥库口令相同, 按回车):
[root@localhost ~]# vim /usr/local/tomcat8/conf/server.xml

Tocmat虚拟主机
基于域名的虚拟主机
[root@localhost ~]# vim /usr/local/tomcat8/conf/server.xml     //需要两个Host

<Host name="www.a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context docBase="/web/a" path="" reloadable="flase"/>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

<Host name="www.b.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">

<Context docBase="/web/b" path="" reloadable="flase"/>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

创建jsp文件

[root@localhost ~]# mkdir /web/a
[root@localhost ~]# mkdir /web/b
[root@localhost ~]# vim /web/a/index.jsp
www.a.com
[root@localhost ~]# vim /web/b/index.jsp
www.b.com
[root@localhost ~]# /usr/local/tomcat8/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat8
Using CATALINA_HOME: /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME: /usr/local/java
Using CLASSPATH: /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Tomcat started.

 

基于端口的虚拟主机
[root@localhost ~]# vim /usr/local/tomcat8/conf/server.xml         //基于端口要两个<Service> 所以 ..........
<Service name="Catalina1">

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>

<Host name="www.a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context docBase="/web/a" path="" reloadable="flase"/>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

</Engine>
</Service>

<Service name="Catalina2">

<Connector port="8090" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>

<Host name="www.a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context docBase="/web/b" path="" reloadable="flase"/>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

</Engine>
</Service>

基于IP地址的虚拟主机
服务器使用多网卡配置多个IP地址，然后配置WEB服务器，把多个网站绑定在不同的IP上。（该方式浪费IP资源，tomcat不支持该方式）

Tomcat多实例配置

[root@localhost ~]# tar xf apache-tomcat-8.5.40.tar.gz
