32453、配置 Tomcat web 控制页面
注意：不要在生产环境使用
# 添加如下内容
[root@localhost local]# vim /usr/local/tomcat/conf/tomcat-users.xml
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<role rolename="manager-script"/>
<role rolename="manager-status"/>
<user username="tomcat" password="tomcat" roles="admin-gui,manager-gui,managerjmx,manager-script,manager-status,admin-script"/>
# 允许访问 Manager App
[root@localhost local]# vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
# 允许访问 Host Manager
[root@localhost local]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
# 重启 Tomcat 服务
[root@node01 local]# systemctl restart tomcat.service
在浏览器访问：http://192.168.3.99:8080/
4、Web 站点部署（Jpress）
[root@localhost ~]# ll
total 192620
-rw-r--r--. 1 root root 2831 Jan 4 21:49 1
-rw-------. 1 root root 1409 Jan 2 12:07 anaconda-ks.cfg
-rw-r--r--. 1 root root 9433364 Jan 2 13:07 apache-tomcat-8.5.20.tar.gz
-rw-r--r--. 1 root root 169971490 Jan 2 13:05 jdk-8u144-linux-x64.rpm
drwxr-xr-x. 2 root root 6 Jan 4 16:38 JspRun!_6.0.0_UTF8
-rw-r--r--. 1 root root 17825359 Jan 4 16:30 JspRun6.0.0_UTF8_1.zip
[root@localhost ~]#mv jpress-web-newest.war /usr/local/tomcat/webapps/（1）配置数据库
[root@localhost bbs]# vim config.properties
dbhost = localhost
dbport=3306
dbuser = bbs
dbpw = 123456
dbname = jsprun
pconnect = 0
tablepre = jrun_
database = mysql
dbcharset =
charset = utf-8
headercharset = 0
tplrefresh = 1
version=5.1
[root@localhost local]# yum -y install mariadb-server
[root@localhost local]# systemctl start mariadb.service
[root@localhost local]# mysql -e "create database jsprun DEFAULT CHARACTER SET utf8;"
或者
MariaDB [(none)]> create database jsprun character set utf8;
[root@localhost local]# mysql -e "grant all on jsprun.* to bbs@'localhost' identified by '123456';"
或者
MariaDB [(none)]> grant all on jsprun.* to bbs@localhost identified by '123456';浏览器访问：http://192.168.3.99:8080/jpress-web-newest/install
5、Tomcat 虚拟主机配置
（1）修改 server.xml
[root@localhost ~]# systemctl stop tomcat.service
[root@localhost bbs]# cd /usr/local/tomcat/conf/
[root@localhost conf]# cp server.xml{,.bak}
# 添加虚拟主机配置
[root@localhost conf]# vim server.xml
</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="www.a.com_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %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="www.b.com_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
（2）虚拟主机目录及文件准备
[root@localhost conf]# mkdir -p /web/{a,b}
[root@localhost conf]# vim /web/a/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP a page</title>
</head>
<body>
<% out.println("Welocome to test site,http://www.a.com");%>
</body>
</html>
[root@localhost conf]# vim /web/b/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP a page</title>
</head>
<body>
<% out.println("Welocome to test site,http://www.b.com");%>
</body>
</html>（3）配置 hosts 解析
[root@localhost conf]# vim /etc/hosts
# 添加：
192.168.3.99 www.a.com www.b.com
（4）重启 Tomcat
[root@localhost conf]# systemctl restart tomcat.service（5）测试
[root@localhost conf]# curl www.a.com
