使用docker部署tomcat服务器

1、拉去tomcat镜像

[root@localhost yum.repos.d]# sudo docker pull docker.io/tomcat:9
9: Pulling from library/tomcat
de44b265507a: Pull complete 
4c2afd91a87d: Pull complete 
89e9bbcfa697: Pull complete 
11be3e613582: Pull complete 
1b9d1e181a2a: Pull complete 
ffd7da68d2ba: Pull complete 
4f4fb700ef54: Pull complete 
cff7298967c0: Pull complete 
Digest: sha256:b19c830294642c0dd863346fbecd190e000b4164df5cc760d1b435012db0a0b6
Status: Downloaded newer image for tomcat:9
docker.io/library/tomcat:9

2、查看tomcat镜像

[root@localhost yum.repos.d]# docker images tomcat
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
tomcat       9         f05fe3cd4f92   10 days ago   470MB

3、通过docker服务创建tomcat守护式容器

[root@localhost yum.repos.d]# docker run -di -p 80:8080 --name=tomcat001 docker.io/tomcat:9
0444152863f24d3d03ad8d87ae217b570a97f6cceaa69b6b27e06881eccc29d0

4、通过tocker服务查看tomcat容器状态，当tomcat容器的状态显示为up时，表明tomcat容器已经启动成功

[root@localhost yum.repos.d]# docker ps -a
CONTAINER ID   IMAGE      COMMAND             CREATED         STATUS         PORTS                                   NAMES
0444152863f2   tomcat:9   "catalina.sh run"   9 seconds ago   Up 9 seconds   0.0.0.0:80->8080/tcp, :::80->8080/tcp   tomcat001

四、通过docker部署mysql数据库

1、拉去mysql镜像

[root@localhost yum.repos.d]# docker pull docker.io/mysql:5.7
5.7: Pulling from library/mysql
20e4dcae4c69: Pull complete 
1c56c3d4ce74: Pull complete 
e9f03a1c24ce: Pull complete 
68c3898c2015: Pull complete 
6b95a940e7b6: Pull complete 
90986bb8de6e: Pull complete 
ae71319cb779: Pull complete 
ffc89e9dfd88: Pull complete 
43d05e938198: Pull complete 
064b2d298fba: Pull complete 
df9a4d85569b: Pull complete 
Digest: sha256:4bc6bc963e6d8443453676cae56536f4b8156d78bae03c0145cbe47c2aad73bb
Status: Downloaded newer image for mysql:5.7
docker.io/library/mysql:5.7

2、查看镜像

[root@localhost yum.repos.d]# docker images mysql
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
mysql        5.7       5107333e08a8   13 months ago   501MB

3、通过docker服务创建mysql守护式容器。这里已经设置了用户和用户密码。

[root@localhost yum.repos.d]# docker run -di --name=mysql001 -p 33506： -e MYSQL_ROOT_PASSWORD=123456 docker.io/mysql:5.7

4、通过docker服务查看mysql容器状态，当容器的状态显示为up时，表明容器已经启动成功

[root@localhost yum.repos.d]# docker ps -a
CONTAINER ID   IMAGE       COMMAND                   CREATED         STATUS         PORTS                                                                NAMES
8bf430c86754   mysql:5.7   "docker-entrypoint.s…"   9 seconds ago   Up 8 seconds   3306/tcp, 33060/tcp, 0.0.0.0:32768->33506/tcp, :::32768->33506/tcp   mysql001
0444152863f2   tomcat:9    "catalina.sh run"         3 minutes ago   Up 3 minutes   0.0.0.0:80->8080/tcp, :::80->8080/tcp                                tomcat001

5、进入mysql容器

[root@localhost yum.repos.d]# docker exec -it 8bf430c86754  bash
bash-4.2# mysql -uroot -p123456

6、然后就可以随便进行操作了
