1.
安装JDK
注意：安装之前需要查看下系统是否安装了openjdk，如果安装了openjdk，请先卸载，否则安装不了oracle官方的jdk
2.
[root@xuegod13 opt]# ls
apache-tomcat-8.5.75.tar.gz jdk-8u321-linux-x64.tar.gz mysql-connector-java-8.0.28.tar.gz
[root@xuegod13 opt]# tar xf jdk-8u321-linux-x64.tar.gz -C /usr/local/
[root@xuegod13 opt]# vim /etc/profile
[root@xuegod13 opt]# . /etc/profile
[root@xuegod13 opt]# java -version
java version "1.8.0_321"
Java(TM) SE Runtime Environment (build 1.8.0_321-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.321-b07, mixed mode)
3.
添加相关配置变量
vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_321
export CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/jar/tools.jar:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
4.
tomcat安装
解压后直接就可以用了
[root@xuegod13 opt]# tar xf apache-tomcat-8.5.75.tar.gz -C /usr/local/
[root@xuegod13 opt]# ls /usr/local/
apache-tomcat-8.5.75 bin etc games include jdk1.8.0_321 lib lib64 libexec sbin share src
[root@xuegod13 opt]# cd /usr/local/
[root@xuegod13 local]# mv apache-tomcat-8.5.75/ tomcat_8.5/
[root@xuegod13 local]# ls
bin etc games include jdk1.8.0_321 lib lib64 libexec sbin share src tomcat_8.5
[root@xuegod13 local]# cd tomcat_8.5/
[root@xuegod13 tomcat_8.5]# ls
bin conf lib logs README.md RUNNING.txt webapps
BUILDING.txt CONTRIBUTING.md LICENSE NOTICE RELEASE-NOTES temp work
[root@xuegod13 tomcat_8.5]# cd bin/
查看Tomcat版本
[root@xuegod13 bin]# ./catalina.sh version
Using CATALINA_BASE: /usr/local/tomcat_8.5
Using CATALINA_HOME: /usr/local/tomcat_8.5
Using CATALINA_TMPDIR: /usr/local/tomcat_8.5/temp
Using JRE_HOME: /usr/local/jdk1.8.0_321
Using CLASSPATH: /usr/local/tomcat_8.5/bin/bootstrap.jar:/usr/local/tomcat_8.5/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Server version: Apache Tomcat/8.5.75
Server built: Jan 17 2022 22:07:47 UTC
Server number: 8.5.75.0
OS Name: Linux
OS Version: 3.10.0-957.el7.x86_64
Architecture: amd64
JVM Version: 1.8.0_321-b07
JVM Vendor: Oracle Corporation
5.
创建tomcat启动脚本
[root@xuegod13 ~]# vim /etc/init.d/tomcat
#
# tomcat startup script for the Tomcat server
#
# chkconfig: 345 80 20
# description: start the tomcat deamon
#
# Source function library
JAVA_HOME=/usr/local/jdk1.8.0_321
export JAVA_HOME
CATALANA_HOME=/usr/local/tomcat_8.5
export CATALANA_HOME
case "$1" in
start)
echo "Starting Tomcat..."
$CATALANA_HOME/bin/startup.sh
;;
stop)
echo "Stopping Tomcat..."
$CATALANA_HOME/bin/shutdown.sh
;;
restart)
echo "Stopping Tomcat..."
$CATALANA_HOME/bin/shutdown.sh
sleep 2
echo
echo "Starting Tomcat..."
$CATALANA_HOME/bin/startup.sh
;;
*)
echo "Usage:$prog{start|stop|restart}"
;;
esac
exit 0
[root@xuegod13 ~]# chmod +x /etc/init.d/tomcat
6.
添加到开机自启动项
[root@xuegod13 init.d]# chkconfig --add tomcat
[root@xuegod13 init.d]# chkconfig tomcat on
[root@xuegod13 init.d]# chkconfig --list tomcat
注：该输出结果只显示 SysV 服务，并不包含
原生 systemd 服务。SysV 配置数据
可能被原生 systemd 配置覆盖。
要列出 systemd 服务，请执行 'systemctl list-unit-files'。
查看在具体 target 启用的服务请执行
'systemctl list-dependencies [target]'。
tomcat 0:关 1:关 2:开 3:开 4:开 5:开 6:关
这里要注意的是：实际环境中，start 和 stop不常用 ，常用的是重启tomcat。tomcat自带的脚本中，startup.sh是好使的，但是shutdown.sh好多时候是关不掉tomcat，生产环境直接用kill杀进程的方法关闭tomcat。
7.
tomcat主配置文件是主目录下conf目录中的server.xml，端口、路径都是在它里面设置的。
context.xml这个是数据源配置文件，数据库连接账号密码都是在里面配置的
这两个文件是工作中最常用的
[root@xuegod13 conf]# ls
Catalina catalina.policy catalina.properties context.xml jaspic-providers.xml jaspic-providers.xsd logging.properties server.xml tomcat-users.xml tomcat-users.xsd web.xml
8.
搭建基于域名的虚拟主机
在server.xml文件是，跳转到最后，在最后一个</Host>标签后面插入如下行
<Host name="www.xuegod13.com" appBase="/var/www/html">
<Context path="" docBase="/var/www/html/web1" />
</Host>
<Host name="www.xuegod13.cn" appBase="/var/www/html">
<Context path="" docBase="/var/www/html/web2" />
</Host>
创建虚拟主机测试环境
[root@xuegod13 conf]# mkdir -p /var/www/html/{web1,web2}
[root@xuegod13 conf]# echo xuegod13.com >/var/www/html/web1/index.html
[root@xuegod13 conf]# echo xuegod13.cn >/var/www/html/web2/index.html
最后打开一台linux主机做测试。
[root@xuegod63 ~]# curl www.xuegod13.com:8080
xuegod13.com
[root@xuegod63 ~]# curl www.xuegod13.cn:8080
xuegod13.cn
注：需要先在测试机(xuegod63)的hosts文件做好映射关系内容，如下
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.31.13 www.xuegod13.com
192.168.31.13 www.xuegod13.cn
9.
安装tomcat-Native
注意:这个包在tomcat8的bin 目录已经提供
先安装依赖包
[root@xuegod13 ~]# yum -y install apr-devel gcc gcc-c++ openssl-devel openssl解压编译安装
[root@xuegod13 ~]# cd /usr/local/tomcat_8.5/
[root@xuegod13 tomcat_8.5]# ls

[root@xuegod13 native]# make -j 4 && make install
#内容省略，但要注意输出最后的一部分内容，如下
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/apr/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the -LLIBDIR
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
#注意，需要做的就是，把/usr/local/apr/lib加到/etc/ld.so.conf中去，还有加一些变量加到环境变量里去
[root@xuegod13 native]# vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/apr/lib
[root@xuegod13 native]# ldconfig #使生效
[root@xuegod13 native]# vim /etc/profile.d/jdk8.sh
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
[root@xuegod13 native]# . /etc/profile.d/jdk8.sh
修改成apr模式
[root@xuegod13 native]# cd /usr/local/tomcat_8.5/conf/
[root@xuegod13 conf]# ls
Catalina context.xml logging.properties tomcat-users.xsd
catalina.policy jaspic-providers.xml server.xml web.xml
catalina.properties jaspic-providers.xsd tomcat-users.xml
[root@xuegod13 conf]# vim server.xml
#修改69行
