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';

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 &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="www.b.com_access_log" suffix=".txt"
             pattern="%h %l %u %t &quot;%r&quot; %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
