说明：由于业务需要使用centos7.6+mysql5.7+jdk8以及其他的java程序，本想在网上找一个现成的，发现镜像都不适合我。

一、yum方式安装mysql

1、编写dockerfile文件

#FROM centos:7FROM xxlaila/centos7.6-jdk1.8LABEL maintainer=‘xxx‘ centos_version=‘7.6‘ mysql_version=‘5.7‘ jdk_version=‘1.8‘#ADD jdk-8u181-linux-x64.tar.gz /usr/local

COPY bootstrap.sh/etc/WORKDIR/usr/local

RUN yum install wget crontabs iproute-y&& wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm \

&& rpm -ivh mysql57-community-release-el7-10.noarch.rpm&& yum install install mysql-server -y --nogpgcheck&& mysqld --initialize --explicit_defaults_for_timestamp --user=mysql&& chmod 777 /etc/bootstrap.sh#ENV PATH/usr/local/jdk/bin:$PATHCOPY my.cnf/etc/my.cnf

COPY createDB.sql/mysql/createDB.sqlCOPY privileges.sql/mysql/privileges.sqlEXPOSE3306 ENTRYPOINT ["/etc/bootstrap.sh"]

CMD ["/usr/sbin/init"]

2、bootstrap.sh文件

#!/bin/bashset -x

#判断mysql root密码是否被赋值，如果没有赋值，给定默认值

MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD:-123456}

#判断mysql是否启动

mysqld--user=mysql &sleep2function start_mysql(){for p in {3..0};doPORT=$(ss -anlp|grep 3306|wc -l)if [ $PORT != 1]; then

echo"Mysql 未启动，启动mysql"mysqld--user=mysql &sleep2

elseecho"Mysql 以启动"

breakfiif [ $p = 0]; then

echo>&2 ‘MySQL 启动失败!‘exit1fi

done

}

start_mysql

#获取mysql初始密码

PASSWORD=$(awk ‘/password/{print $NF}‘ /var/log/mysqld.log)

echo"修改mysql密码..."mysql--connect-expired-password -uroot -p"$PASSWORD" -e "alter user [email protected] identified by ‘$MYSQL_ROOT_PASSWORD‘" > /dev/null 2>&1#判断密码是否修改成功#if [ $? -eq 0 ];then# echo"Mysql密码修改成功..."

#else# echo"Mysql密码修改失败..."# exit1#fi

#设置环境变量

MYSQL="mysql --protocol=socket -uroot -p${MYSQL_ROOT_PASSWORD}"#初始化sql

echo"1. 初始化mysql..."#1、判断数据库test_db是否存在

$MYSQL-e "use test_db;" > /dev/null 2>&1

if [ $? != 0]; then

echo‘2. creating database...‘$MYSQL< /mysql/createDB.sqlecho‘4. flush privileges....‘$MYSQL< /mysql/privileges.sql

fi

# check mysql status

#echo `service mysql status`

echo‘5. mysql for test_db is ready...‘

3、my.cnf

[mysqld]

server-id=1max_connections=3000#basedir= /usr/local/mysql

#datadir= /data/mysql/data

port= 3306#secure_file_priv=/data/mysql/data

query_cache_type=1query_cache_size=120M

query_cache_min_res_unit=4096character_set_server=utf8

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘general_log=ON

slow_query_log=1long_query_time=2#log-error=/data/mysql/logs/mysql.err

#log_bin=/data/mysql/logs/mysql-bin

#slow-query-log-file=/data/mysql/logs/slowquery.log

#socket= /data/mysql/mysql.sock

symbolic-links=0character-set-server=gbk

#######################

[client]

#socket=/data/mysql/mysql.sock

[mysql]default-character-set=gbk

二、基于源码安装mysql

1、dockerfile文件

FROM centos:7LABEL maintainer=‘xxx‘ centos_version=‘7.7‘ mysql_version=‘5.7‘ jdk_version=‘1.8‘#拷贝并解压mysql、jdk软件包

ADD jdk-8u181-linux-x64.tar.gz /usr/local

ADD mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz /usr/local

WORKDIR/usr/local

COPY setup.sh/usr/bin/RUN ln-s mysql-5.7.24-linux-glibc2.12-x86_64 mysql&& ln -s jdk1.8.0_181 jdk&& groupadd -r mysql&& useradd -r -g mysql mysql&& yum install -y crontabs libaio libaio-devel numactl.x86_64 iproute&& cat /data/cron |crontab&& chmod 777 /usr/bin/setup.sh

ENV PATH/usr/local/mysql/bin:/usr/local/jdk/bin:$PATH

EXPOSE3306 #拷贝初始化mysql的sql文件

COPY my.cnf/etc/my.cnf

COPY createDB.sql/mysql/createDB.sqlCOPY privileges.sql/mysql/privileges.sql#执行初始化脚本文件

ENTRYPOINT ["setup.sh"]

2、setup.sh文件信息

#!/bin/bashset -x

echo"----开始初始化mysql----------------------"mkdir-p /data/mysql/{data,logs,conf,mysql.pid}

touch/data/mysql/logs/mysql.err

chown-R mysql.mysql /data/mysql

#curl-o /data/mysql/conf/my.cnf http://124.207.22.13/logs/Math/my.cnf

#ln -s /data/mysql/conf/my.cnf /etc/my.cnf/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data

cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

chmod777 /etc/init.d/mysqld

#ln-s /usr/local/mysql/bin/*/usr/bin/

echo "初始化数据库完毕.数据持目录:/data/mysql"

echo "设置变量"

passwd="$(awk ‘/localhost/{print $NF}‘ /data/mysql/logs/mysql.err|head -1)"

dbinit=( mysql --connect-expired-password -uroot -p"$passwd" )

#sed -i ‘/\[mysqld\]/a\skip-grant-tables‘ /etc/my.cnf

echo "启动数据库"

#启动数据库并判断状态

sed -i "47cdatadir=/data/mysql/data" /etc/init.d/mysqld

function start_mysql(){

/etc/init.d/mysqld restart && sleep 3

echo "启动后查看进程"

port=$(ss -lntp|grep "3306"|wc -l)

for p in {3..0}; do

if [ $port -ne 1 ];then

echo "Mysql启动失败-重新启动"

/etc/init.d/mysqld restart && sleep 2

else

echo "Mysql 已经启动"

break

fi

if [ "$p" = 0 ];then

echo >&2 ‘MySQL 启动失败!‘

exit 1

fi

done

}

start_mysql

echo "修改数据库密码"

#passinit="alter user [email protected] identified by ‘123456‘;"

#echo $passinit | $dbinit

#echo $dbinit

mysql --connect-expired-password -uroot -p"$passwd" -e "alter user [email protected] identified by ‘123456‘;"

echo "$passwd" 密码

#echo "重新启动mysql"

#start_mysql

#初始化sql

#mysql=( mysql --protocol=socket -uroot -hlocalhost --socket="/data/mysql/mysql.sock" -p123456)

mysql="mysql --protocol=socket -uroot -hlocalhost --socket=/data/mysql/mysql.sock -p123456"

#echo ‘1. starting mysql...‘

#service mysql start

$mysql -e "use test_db;" > /dev/null 2>&1

if [ $? != 0 ]; then

echo ‘2. creating database...‘

$mysql < /mysql/createDB.sql

set password

echo ‘3. flush privileges....‘

$mysql < /mysql/privileges.sql

fi

# check mysql status

#echo `service mysql status`

echo ‘4. mysql for test_db is ready...‘

3、my.cnf

[mysqld]

server-id=1max_connections=3000basedir= /usr/local/mysql

datadir= /data/mysql/data

port= 3306secure_file_priv=/data/mysql/data

query_cache_type=1query_cache_size=120M

query_cache_min_res_unit=4096character_set_server=utf8

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘general_log=ON

slow_query_log=1long_query_time=2log-error=/data/mysql/logs/mysql.err

log_bin=/data/mysql/logs/mysql-bin

slow-query-log-file=/data/mysql/logs/slowquery.log

socket= /data/mysql/mysql.sock

symbolic-links=0character-set-server=gbk

#######################

[client]

socket=/data/mysql/mysql.sock

[mysql]default-character-set=gbk

注：基于源码安装比基于yum安装方式，最后生成的镜像大一点多G，如下：

1.78GB是yuam方式安装

3.31GB这个是源码安装，这种方式安装以后，镜像实在是有点太大了。

总的来说，这个镜像还是太臃肿，最好是几百兆就完美了。
