温馨提示：启动Tomcat需要提前配置好Java运行环境。

若未安装java环境可参考

CentOS 7.9下安装配置Java环境 | Ever (xiaoduz.com)

1、安装tomcat 9.0.87

1.1、创建安装目录

[xiaodu root /tmp]# mkdir -p /usr/share/tomcat/
[xiaodu root /tmp]# cd /usr/share/tomcat/

1.2、解压安装包

[xiaodu root /usr/share/tomcat]# tar xf /tmp/apache-tomcat-9.0.87.tar.gz -C /usr/share/tomcat/

[xiaodu root /usr/share/tomcat]# mv apache-tomcat-9.0.87/* .

1.3加入环境变量配置

vim /etc/profile

JAVA_HOME=/usr/lib/jvm/java
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
CATALINA_BASE=/usr/share/tomcat
CATALINA_HOME=/usr/share/tomcat
export JAVA_HOME PATH CLASSPATH CATALINA_BASE CATALINA_HOME

使配置文件生效

source /etc/profile

查看是否生效

echo $CATALINA_BASE

echo $CATALINA_HOME

2、tomcat开启PID文件

配置tomcat启动后将进程号保存至 ./bin/tomcat.pid 文件。

修改 catalina.sh 文件，在 PRGDIR 下面一行添加 CATALINAPID 参数行，如下

CATALINA_PID=$PRGDIR/tomcat.pid

[xiaodu root /usr/share/tomcat/bin]# vim catalina.sh

注意路径

3、启动tomcat

[xiaodu root /usr/share/tomcat/bin]# ./startup.sh
Using CATALINA_BASE: /usr/share/tomcat
Using CATALINA_HOME: /usr/share/tomcat
Using CATALINA_TMPDIR: /usr/share/tomcat/temp
Using JRE_HOME: /usr/local/soft/jdk1.8.0_401/jre
Using CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Using CATALINA_PID: /usr/share/tomcat/bin/tomcat.pid
Tomcat started.

查看8080端口
[xiaodu root /usr/share/tomcat/bin]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 :
LISTEN 0 1 [::ffff:127.0.0.1]:8005 [::]:*
LISTEN 0 100 [::]:8080 [::]:*
LISTEN 0 128 [::]:22 [::]:*
LISTEN 0 100 [::1]:25 [::]:*

验证访问页面

8080端口

4.彩蛋

配置system管理启动脚本

停掉tomcat

[xiaodu root /usr/share/tomcat/bin]# ./shutdown.sh
Using CATALINA_BASE: /usr/share/tomcat
Using CATALINA_HOME: /usr/share/tomcat
Using CATALINA_TMPDIR: /usr/share/tomcat/temp
Using JRE_HOME: /usr/local/soft/jdk1.8.0_401/jre
Using CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Using CATALINA_PID: /usr/share/tomcat/bin/tomcat.pid
Tomcat stopped.

4.1查看tomcat.pid文件

4.1.1编写system启动脚本

vim /etc/systemd/system/tomcat-console.service
