Tomcat部署实战！

Tomcat部署及优化

1.Tomcat安装部署

2.虚拟主机配置

3.Tomcat优化

Tomcat介绍

1.免费的、开放源代码的Web应用服务器
2.Apache软件基金会(Apache Software Foundation)Jakarta项目中的- -个核心项目
3.由Apache、 Sun和一些公司及个人共同开发而成
4.深受Java爱好者的喜爱，并得到部分软件开发商的认可
5.目前比较流行的Web应用服务器

Tomcat部署步骤

1.下载并安装jdk

2.安装并启动Tomcat

3.配置虚拟主机

设置环境变量

1.编辑/etc/profile文件：

export JAVA_HOME=/usr/java/jdk1.8.0_171-amd64

export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt,jar

export PATH=$JAVA_HOME/bin:$PATH

2.使环境变量生效的命令：

[root@localhost~]#source /etc/profile

3.查看jdk版本的命令：

[root@localhost~]#java -version

安装、启动Tomcat

1.下载安装包：

[root@localhost ~]# wget http://mirrors. shu.edu.cn/apache/tomcat/tomcat-9/v9.0.8/bin/apache-tomcat-9.0.8.tar.gz

2.将安装包移动到/usr/local下重命名：

[root@localhost ~]# mv apache-tomcat-9.0.8 /usr/ocal/tomcat

3.启动Tomcat：

[root@localhost ~]# /usr/local/tomcat/bin/startup.sh

Tomcat启动时间

1.缩短启动时间的命令
/usr/java/jdk1.8.0_171-amd64/je/lib/security/java.security文件

securerandom.source=file:/dev/random改为urandom

//设置环境变量：
[root@localhost jdk1.8.0_201-amd64]# vim /etc/profile
按大写字母G到末行，按小写字母o在下行插入以下内容：

export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$PATH

此时使用宿主机浏览器输入地址：192.168.18.145:8080，可访问到Tomcat的主页：

此时Tmocat部署成功，谢谢观看！
