案例实施

1. 基础环境准备

(1)导入软件包

下载并解压软件包:

[root@master ~]# tar -xf Pig.tar.gz
[root@master ~]# ll Pig
total 206752
-rw------- 1 root root 211696640 Jan 12 17:24 CentOS_7.9.2009.tar
drwxr-xr-x 2 root root        85 Jan  5 08:58 mysql
drwxr-xr-x 3 root root        37 Jan  5 08:56 nginx
drwxr-xr-x 2 root root        97 Jan  5 08:56 service
drwxr-xr-x 3 root root     12288 Jan  5 08:56 yum

导入CentOS:7.9.2009镜像:

[root@master ~]# docker load -i Pig/CentOS_7.9.2009.tar 
Loaded image: centos:centos7.9.2009

(2)启动Kubernetes集群

初始化Kubernetes集群:
[root@master ~]# init-cluster
查看集群状态:
[root@master ~]# kubectl cluster-info
Kubernetes control plane is running at https://apiserver.cluster.local:6443
CoreDNS is running at https://apiserver.cluster.local:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.

2. 容器化部署MariaDB

(1)编写Dockerfile

编写init.sh脚本:

[root@master ~]# cd Pig/
[root@master Pig]# vi mysql_init.sh 
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 8
mysqladmin -u root password 'root'
mysql -uroot -proot -e "grant all on *.* to 'root'@'%' identified by 'root';flush privileges;"
mysql -uroot -proot -e "source /opt/pig.sql;source /opt/pig_codegen.sql;source /opt/pig_config.sql;source /opt/pig_job.sql;"

编写yum源:

[root@master Pig]# vi local.repo
[pig]
name=pig
baseurl=file:///root/yum
gpgcheck=0
enabled=1

编写Dockerfile文件:

[root@master Pig]# vi Dockerfile-mariadb 
FROM centos:centos7.9.2009
MAINTAINER Chinaskills
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
ENV LC_ALL en_US.UTF-8
RUN yum -y install mariadb-server
COPY mysql /opt/
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

(2)构建镜像

构建镜像:

[root@master Pig]# docker build -t pig-mysql:v1.0 -f Dockerfile-mariadb .
Sending build context to Docker daemon  890.9MB
Step 1/12 : FROM centos:centos7.9.2009

3. 容器化部署Redis

(1)编写Dockerfile


编写Dockerfile文件:
[root@master Pig]# vi Dockerfile-redis
FROM centos:centos7.9.2009
MAINTAINER Chinaskills
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
RUN yum -y install redis
RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/redis.conf && \
     sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
EXPOSE 6379
CMD ["/usr/bin/redis-server","/etc/redis.conf"]

(2)构建镜像

[root@master Pig]# docker build -t pig-redis:v1.0 -f Dockerfile-redis .
Sending build context to Docker daemon  890.9MB
Step 1/9 : FROM centos:centos7.9.2009
 ---> eeb6ee3f44bd
Step 2/9 : MAINTAINER Chinaskills
 ---> Using cache
 ---> 815a4a5f2242
Step 3/9 : RUN rm -rf /etc/yum.repos.d/*
 ---> Using cache
 ---> 6afa0315cb5b
Step 4/9 : COPY local.repo /etc/yum.repos.d/

Step 6/9 : RUN yum -y install redis
 ---> Using cache
 ---> 2d0b65ca48f0
Step 7/9 : RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/redis.conf &&     sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
