1、安装 JDK
[root@localhost ~]# ls anaconda-ks.cfg apache-tomcat-8.5.20.tar.gz jdk-8u144-linux-x64.rpm [root@localhost ~]# yum install -y jdk-8u144-linux-x64.rpm
2、部署 Tomcat
[root@localhost ~]# tar xf apache-tomcat-8.5.20.tar.gz -C /usr/local [root@localhost ~]# cd /usr/local/ [root@localhost java]# ln -sv apache-tomcat-8.5.20/ tomcat ‘tomcat’ -> ‘apache-tomcat-8.5.20/’
（1）配置 Tomcat 环境变量
[root@localhost local]# vim /etc/profile.d/tomcat.sh # TOMCAT export CATALINA_HOME=/usr/local/tomcat # PATH export PATH=$PATH:$CATALINA_HOME
（2）配置 Tomcat pid 文件和相关参数
[root@localhost local]# vim /usr/local/tomcat/bin/setenv.sh # add tomcat pid CATALINA_PID="$CATALINA_HOME/tomcat.pid" # add java opts JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=512m -Xms512M -Xmx512M -XX:MaxNewSize=256m"
（3）配置 Tomcat 服务脚本
[root@localhost local]# vim /usr/lib/systemd/system/tomcat.service [Unit] Description=Apache Tomcat Web Application ContainerAfter=syslog.target network.target [Service] Type=forking PIDFile=/usr/local/tomcat/tomcat.pid ExecStart=/usr/local/tomcat/bin/catalina.sh start ExecReload=/bin/kill -s HUP MAINPID ExecStop=/bin/kill−s QUIT MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target
（4）启动服务
[root@localhost local]# systemctl daemon-reload [root@localhost local]# systemctl status tomcat.service [root@localhost local]# systemctl enable tomcat.service [root@localhost local]# systemctl is-enabled tomcat.service enabled [root@localhost local]# systemctl start tomcat.service # 查看 Tomcat 开启端口状态 [root@localhost ~]# netstat -lnutp | grep :8080 tcp6 0 0 :::8080 :::* LISTEN 3060/java # 查看当前运行进程 [root@localhost ~]# ps -ef | grep java root 3060 1 0 13:16 ? 00:00:05 /usr/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -server -XX:PermSize=256M -XX:MaxPermSize=512m -Xms512M -Xmx512M -XX:MaxNewSize=256m -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start root 3910 2183 0 13:32 pts/0 00:00:00 grep --color=auto java
（5）提升 Tomcat 启动速度
# 查看是否有足够的熵来用于产生随机数 [root@localhost local]# cat /proc/sys/kernel/random/entropy_avail 1101 # 安装rngd服务（熵服务，增大熵池） [root@localhost ~]# yum install rng-tools # 开机自启动服务 [root@localhost ~]# systemctl enable --now rngd # 再次查看 [root@localhost local]# cat /proc/sys/kernel/random/entropy_avail 3245
3、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

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
