## 获取 Tomcat 镜像 ##

*  语法：`docker pull tomcat`（这种方法是获取最新的Tomcat镜像）
 *  示例：

[root@izbp13xko46hud9vfr5s94z ~]# docker pull tomcat 
    Using default tag: latest
    latest: Pulling from library/tomcat
    cc1a78bfd46b: Pull complete 
    d2c05365ee2a: Pull complete

    Status: Downloaded newer image for tomcat:latest
    [root@izbp13xko46hud9vfr5s94z ~]#

## 启动Tomcat容器实例 ##

*  语法：`docker run --name tomcat -d -it --rm -p 8080:8080 tomcat`  
    说明：`--rm`:表示当关闭或者销毁当前容器实例进程时，同时销毁容器实例。
 *  示例：

[root@izbp13xko46hud9vfr5s94z ~]# docker run --name tomcat -d -it --rm -p 8080:8080 tomcat
    1909f6a6792b456c07de717e2111548e71dd39c49fabd3a99c12df5d25450c01
    [root@izbp13xko46hud9vfr5s94z ~]#

注意：如果需要通过非当前主机外部的浏览器访问Tomcat，需要通过`-p 8080:8080`指定容器向外部暴露的端口。

## 实例化Tomcat容器实例 ##

*  语法：`docker restart tomcat`（tomcat是当前实例的名称，也可以通过当前实例的容器ID来重启）
 *  示例：

[root@izbp13xko46hud9vfr5s94z ~]# docker restart tomcat 
    tomcat
    [root@izbp13xko46hud9vfr5s94z ~]#

## 关闭Tomcat容器实例 ##

*  语法：`docker stop tomcat`（tomcat是当前实例的名称，也可以通过当前实例的容器ID来重启）
 *  示例：

[root@izbp13xko46hud9vfr5s94z ~]# docker stop tomcat 
    tomcat
    [root@izbp13xko46hud9vfr5s94z ~]#

## 启动Tomcat容器实例 ##

*  语法：`docker start tomcat`
 *  示例：

[root@izbp13xko46hud9vfr5s94z ~]# docker start tomcat 
    tomcat
    [root@izbp13xko46hud9vfr5s94z ~]#

## 查看Tomcat容器实例进程信息 ##

*  通过`docker top tomcat`查看

[root@izbp13xko46hud9vfr5s94z ~]# docker top tomcat 
    UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD

    [root@izbp13xko46hud9vfr5s94z ~]#

*  通过`ps -ef | grep tomcat`查看

[root@izbp13xko46hud9vfr5s94z ~]# ps -ef | grep tomcat 
    root     29232 29214  0 10:49 pts/0    00:00:02 /docker-java-home/jre/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dorg.apache.catalina.security.SecurityListener.UMASK=0027 -Dignore.endorsed.dirs= -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start

[root@izbp13xko46hud9vfr5s94z ~]# docker kill -s KILL tomcat 
    tomcat
    [root@izbp13xko46hud9vfr5s94z ~]# docker ps 
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
