Tomcat deployment of combat!

Tomcat deployment and optimization

1.Tomcat installation and deployment

2. Virtual Host Configuration

3.Tomcat optimization

Tomcat Introduction

1. The free, open-source Web application server
2.Apache Software Foundation (Apache Software Foundation) Jakarta Project - - core projects
3. by the Apache, Sun and a number of companies and individuals jointly developed with

Tomcat deployment steps

1. Download and install jdk

2. Install and start Tomcat

3. Configure virtual hosts

Set Environment Variables

1. Edit / etc / profile file:

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. The entry into force of the command environment variables:

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

3. Review the jdk version of the command:

[root@localhost~]#java -version

Installation, start Tomcat

1. Download the installation package:

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

2. The installation package is moved to the / usr / local rename:

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

3. Start Tomcat:

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

Tomcat startup time

1. shorten start-up time of command
/usr/java/jdk1.8.0_171-amd64/je/lib/security/java.security file

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