Check the java version
rpm -qa | grep java
Clear the system comes with the Java
RPM -e - nodeps rpm -qa | grep java
Create java, tomcat directory
mkdir /usr/local/java/
tar -zxvf jdk-8u191-linux-x64.tar.gz -C /usr/local/java
mkdir /usr/local/tomcat/
tar -zxvf apache-tomcat-8.5.35.tar.gz -C /usr/local/tomcat
Set the environment variable:
gedit / etc / Profile
JAVA_HOME=/usr/local/java/jdk1.8.0_191
CLASSPATH=.:$JAVA_HOME/lib.tools.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH
Set to take effect
source / etc / profile
Configuring tomcat server.xml
server.xml can configure the ports, coding and configuration items, and so on, we are here in a port, the default of 8080, modified to 80
gedit /usr/local/tomcat/apache-tomcat-8.5.35/conf/server.xml
将<Connector port="8080" protocol="HTTP/1.1"
改成<Connector port="80" protocol="HTTP/1.1"
Add firewall port 80/8080
Firewall-cmd = --zone public --add-Port = 8080 / tcp --permanent
Firewall---zone cmd = = public --add-Port 80 / tcp --permanent
# refresh the firewall its entry into force
sudo firewall-cmd --reload
firewall-cmd --zone = public --list-ports # View firewall to release the list of ports
启动tomcat
/usr/local/tomcat/apache-tomcat-8.5.35/bin/startup.sh
Set boot from the start
If you want to boot from the start tomcat, configuration is as follows:
chmod + the X-/etc/rc.d/rc.local
gedit /etc/rc.d/rc.local
Add the following lines in the file:
export JAVA_HOME=/usr/local/java/jdk1.8.0_191
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
/usr/local/tomcat/bin/startup.sh
配置tomcat的jdk环境变量
yum -y install vim
gedit /usr/local/tomcat/apache-tomcat-8.5.35/bin/catalina.sh
在 OS specific support. 前面加入如下代码：
JAVA_HOME=/usr/local/java/jdk1.8.0_191
JRE_HOME=$JAVA_HOME/jre
配置tomcat8开机启动
在/usr/lib/systemd/system目录下增加tomcat8.service文件，内容如下:
gedit /usr/lib/systemd/system/tomcat.service

RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
允许tomcat开机启动
