Posted 2021-09-05 人间失格727

一.创建ssh镜像

1.创建镜像目录

2. 创建编写dockerfile文件 

3. 生成镜像 

4. 启动容器并修改root密码

二. 构建Systemctl镜像

1.创建镜像目录方便管理

 2.创建编写dockerfile文件

3. 生成镜像

 4.启动容器，并挂载宿主机目录挂载到容器中，和进行初始化

5.进入容器 

 或者用第二种方法：

三、构建nginx镜像 

1.创建镜像目录方便管理

 2.创建编写dockerfile文件

 3. 编写脚本

4.生成镜像

 

 

5.浏览器访问测试

四、构建tomcat 镜像 

以下同流程同上面一样，这里就不操作演示了，跟着命令打就行了

1.创建镜像目录方便管理

mkdir /opt/tomcat
cd /opt/tomcat
cp /opt/jdk-8u91-linux-x64.tar.gz /opt/tomcat
cp /opt/apache-tomcat-8.5.16.tar.gz /opt/tomcat

2.创建编写dockerfile文件

vim Dockerfile

FROM centos:7
MAINTAINER this is tomcat image <clj>
ADD jdk-8u91-linux-x64.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv jdk1.8.0_91 /usr/local/java
ENV JAVA_HOME /usr/local/java
ENV JRE_HOME ${JAVA_HOME}/jre
ENV CLASSPATH .:${JAVA_HOME}/lib:${JRE_HOME}/lib
ENV PATH $JAVA_HOME/bin:$PATH
ADD apache-tomcat-8.5.16.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv apache-tomcat-8.5.16 /usr/local/tomcat
EXPOSE 8080
#CMD ["/usr/local/tomcat/bin/catalina.sh","run"]
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]

3. 生成镜像

docker build -t tomcat:centos .

docker run -d --name tomcat01 -p 1216:8080 tomcat:centos 
 

4.浏览器访问测试

 
http://192.168.80.10:1216
 

五、构建mysql镜像

1.创建镜像目录方便管理

mkdir /opt/mysqld
cd /opt/mysqld
 

2.创建编写dockerfile文件

vim Dockerfile

FROM centos:7
MAINTAINER this is mysql image <clj>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
RUN useradd -M -s /sbin/nologin  mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/
WORKDIR /usr/local/src/mysql-5.7.20/
RUN cmake \\
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \\
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \\
-DSYSCONFDIR=/etc \\
-DSYSTEMD_PID_DIR=/usr/local/mysql \\
-DDEFAULT_CHARSET=utf8  \\
-DDEFAULT_COLLATION=utf8_general_ci \\
-DWITH_INNOBASE_STORAGE_ENGINE=1 \\
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \\
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \\
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \\
-DMYSQL_DATADIR=/usr/local/mysql/data \\
-DWITH_BOOST=boost \\
-DWITH_SYSTEMD=1 && make && make install
RUN chown -R mysql:mysql /usr/local/mysql/
RUN rm -rf /etc/my.cnf
ADD my.cnf /etc/
RUN chown mysql:mysql /etc/my.cnf
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
WORKDIR /usr/local/mysql/
RUN bin/mysqld \\
--initialize-insecure \\
--user=mysql \\
--basedir=/usr/local/mysql \\
--datadir=/usr/local/mysql/data
RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
EXPOSE 3306
ADD run.sh /usr/local/src
RUN chmod 755 /usr/local/src/run.sh
RUN sh /usr/local/src/run.sh
#CMD ["/usr/sbin/init"]

3.编写my.cnf脚本

vim my.cnf
[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
 

4.编写run.sh脚本

vim run.sh
#!/bin/bash
/usr/local/mysql/bin/mysqld    
systemctl enable mysqld

 5.创建新镜像、启动容器，并进行初始化

docker build -t mysql:centos .
#启动容器，并进行初始化
docker run --name=mysql_server -d -P --privileged mysql:centos /usr/sbin/init &
 

6.进容器给权限

docker ps -a
CONTAINER ID   IMAGE          COMMAND             CREATED          STATUS          PORTS                     NAMES
f9a4d8f6c65f   mysql:centos   "/usr/sbin/init"    17 seconds ago   Up 16 seconds   0.0.0.0:49153->3306/tcp   mysql_server
 

7.进入容器，授权远程连接 mysql

docker exec -it f9a4d8f6c65f /bin/bash

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
grant all privileges on *.* to 'root'@'localhost' identified by 'abc123';
flush privileges;
 

8.在客户端连接mysql容器

mysql -h 192.168.80.10 -u root -P 49153 -pabc123
