查看yum包含的jdk版本

[root@suhw ~]# yum search java

安装jdk

[root@suhw ~]# yum install java-1.8.0-openjdk-devel.x86_64

环境变量配置

将以下三行内容写入/etc/profile中，JAVA_HOME以实际为准

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

安装校验

[root@suhw ~]# source /etc/profile
[root@suhw ~]# java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

安装Tomcat

下载

[root@suhw ~]# cd /usr/local/

[root@suhw local]# wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.5.55/bin/apache-tomcat-8.5.55.tar.gz

解压

[root@suhw local]# tar -zxvf apache-tomcat-8.5.55.tar.gz 
# 修改名称
[root@suhw local]# mv apache-tomcat-8.5.55 tomcat

启动

[root@suhw ~]# /usr/local/tomcat/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

关闭

[root@suhw ~]# /usr/local/tomcat/bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

测试

查看默认端口是否监听

[root@suhw tomcat]# lsof -i:8080
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    9233 root   52u  IPv6  62224      0t0  TCP *:webcache (LISTEN)

默认端口配置在/usr/local/tomcat/conf/server.xml中

69     <Connector port="8080" protocol="HTTP/1.1"
70                connectionTimeout="20000"
71                redirectPort="8443" />

访问ip:port，出现下图即为配置成功

注：可能需要关闭防火墙

[root@suhw tomcat]# firewall-cmd --state
running

[root@suhw tomcat]# systemctl stop firewalld.service

CAS安装

下载

下载地址

https://github.com/apereo/cas/releases/tag/v4.0.0

解压

[root@suhw ~]# unzip cas-server-4.0.0-release.zip 
[root@suhw ~]# cd cas-server-4.0.0/modules/
# 重命令为 cas.war
[root@suhw modules]# mv cas-server-webapp-4.0.0.war cas.war
# 将cas.war 拷贝至 tomcat/webapps/ 下
[root@suhw modules]# cp cas.war /usr/local/tomcat/webapps/

配置

tomcat会自动解析war包，构建web项目cas

[root@suhw ~]# ll /usr/local/tomcat/webapps/
total 24460
drwxr-x---.  7 root root      108 Jun  3 12:05 cas
-rw-r--r--.  1 root root 25038970 Jun  3 12:05 cas.war
drwxr-x---. 16 root root     4096 Jun  3 11:12 docs
drwxr-x---.  6 root root       83 Jun  3 11:12 examples
drwxr-x---.  5 root root       87 Jun  3 11:12 host-manager
drwxr-x---.  5 root root      103 Jun  3 11:12 manager
drwxr-x---.  3 root root      283 Jun  3 11:12 ROOT

端口修改

[root@suhw ~]# vi /usr/local/tomcat/webapps/cas/WEB-INF/cas.properties 

确保 cas与tomcat端口一致

20 server.name=http://localhost:8080
21 server.prefix=${server.name}/cas

去除https校验

cas默认使用https模式，由于没配置证书，所以取消https

1、修改/usr/local/tomcat/webapps/cas/WEB-INF/deployerConfigContext.xml

末尾增加p:requireSecure="false"

90     <!-- Required for proxy ticket mechanism. -->
91     <bean id="proxyAuthenticationHandler"
92           class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
93           p:httpClient-ref="httpClient" p:requireSecure="false" />

2、修改/usr/local/tomcat/webapps/cas/WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml

将cookieSecure置为false

 31                 p:cookieSecure="false"

3、修改/usr/local/tomcat/webapps/cas/WEB-INF/spring-configuration/warnCookieGenerator.xml

同样将cookieSecure置为false

 32                 p:cookieSecure="false"

重启tomcat

重启完成后访问http://ip:port/cas/login

在usr/local/tomcat/webapps/cas/WEB-INF/deployerConfigContext.xml中有默认用户名密码

username	password
casuser	Mellon

    109         <property name="users">
    110             <map>
    111                 <entry key="casuser" value="Mellon"/>
    112             </map>
    113         </property>

使用默认用户名密码登录成功效果如下

退出登录访问/cas/logout即可
