Apache利用JDK自身keytool实现HTTPS
因为一个偶然机会，想把自己的webserver通过https加密访问，这里就采用JDK自带的keytool工具实现，tomcat官方也推荐这种方式，英文好的同学走这里：https://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html
实验环境：
os: centos 6.6 x86_64
tomcat: tomcat7(tomcat6 too)
jdk: 1.7,1.6（只要有keytool就行）
首先，你的tomcat环境是可以正常运行的，这个不在这里的讨论范围之内。
1.生成 keystore
[root@test conf]# keytool -genkey -v -alias tomcat -keyalg RSA -keystore mykeystore Enter keystore password: #设置密码 Re-enter new password: #重复一次 What is your first and last name? [Unknown]: Alex Lu #随便填 What is the name of your organizational unit? [Unknown]: visionet #随便填 What is the name of your organization? [Unknown]: visionet #随便填 What is the name of your City or Locality? [Unknown]: SH #随便填 What is the name of your State or Province? [Unknown]: SH #随便填 What is the two-letter country code for this unit? [Unknown]: ZH #随便填 Is CN=Alex Lu, OU=visionet, O=visionet, L=SH, ST=SH, C=ZH correct? [no]: Y #这里要Y，确认前面信息。 Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 90 days for: CN=Alex Lu, OU=visionet, O=visionet, L=SH, ST=SH, C=ZH Enter key password for <tomcat> (RETURN if same as keystore password): #默认回车即可，不需要设置太多密码 [Storing mykeystore] [root@test conf]# ls Catalina catalina.policy catalina.properties context.xml logging.properties mykeystore server.xml tomcat-users.xml web.xml
注意：-keystore是用来指定keystore保存位置，如果不加参数默认保存的当前用户家目录为~/.keystore
-validity 可以用来指定证书有效期，单位为天，缺省值为90天。
2.备份$tomcatdir/conf/server.xml To $tomcatdir/conf/server.xml.bak
cp $tomcatdir/conf/server.xml $tomcatdir/conf/server.xml
3.修改server.xml
a.注释一下：（tomcat注释用：<!-- XXXX --> ） ###如何也想保留http访问，可以不注释
<!-- <Connector executor="tomcatThreadPool" port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> -->
b.取消下面注释
<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" />
c.增加keystoreFile和keystorePass
<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="conf/mykeystore" keystorePass="123456"/>
keystoreFile=跟keystore文件位置
keystorePass=跟当时keytool命令执行时输入的密码
4. 重启tomcat
[root@test conf]# ../bin/catalina.sh stop && ../bin/catalina.sh start Using CATALINA_BASE: /home/pms/apache-tomcat-6.0.44 Using CATALINA_HOME: /home/pms/apache-tomcat-6.0.44 Using CATALINA_TMPDIR: /home/pms/apache-tomcat-6.0.44/temp Using JRE_HOME: /home/pms/jdk1.7.0_65 Using CLASSPATH: /home/pms/apache-tomcat-6.0.44/bin/bootstrap.jar Using CATALINA_BASE: /home/pms/apache-tomcat-6.0.44 Using CATALINA_HOME: /home/pms/apache-tomcat-6.0.44 Using CATALINA_TMPDIR: /home/pms/apache-tomcat-6.0.44/temp Using JRE_HOME: /home/pms/jdk1.7.0_65 Using CLASSPATH: /home/pms/apache-tomcat-6.0.44/bin/bootstrap.jar [root@test conf]# netstat -ntlup | grep -e "80\|443" tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21960/java tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 21960/java tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 21960/java tcp 0 0 0.0.0.0:8009 0.0.0.0:* LISTEN 21960/java [root@test conf]#
5. successful ！
