vitess基础镜像构建流程Centos

时间：2023-02-08 04:22:12

以下列出了构建vitess使用的Centos镜像的简单流程，由于较早基础版本是Centos7.2的，重新构建可以基于最新的Centos版本构建

1.基础镜像拉取

#拉取官方版本

docker pull centos:7.2.1511

官方镜像地址: https://hub.docker.com/_/centos/

2. 修改镜像源，可以选择阿里云的源地址或者内部源地址

CentOS-7.2-Base.repo

[CentOS]

name=CentOS-7.2 - Base

#additional packages that may be useful

[extras]

name=CentOS-$releasever - Extras - mirrors.aliyun.com

failovermethod=priority

baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/

        http://mirrors.aliyuncs.com/centos/$releasever/extras/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras

gpgcheck=1

gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

epel.repo

[epel]

name=Extra Packages for Enterprise Linux 7 - $basearch

#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch

metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch

failovermethod=priority

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

[epel-debuginfo]

name=Extra Packages for Enterprise Linux 7 - $basearch - Debug

#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug

metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

[epel-source]

name=Extra Packages for Enterprise Linux 7 - $basearch - Source

#baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS

metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

3. 依赖程序安装

#安装vim

yum install vim -y

#安装wget

yum install wget -y

#安装rzsz

yum install lrzsz -y

#安装ssh

yum install openssh-server -y

#安装net-tools(包含netstat)

yum install net-tools -y

#重置镜像默认密码

echo root:xxxxxxxxxxxxxxxx | chpasswd

#安装sudu权限

yum install sudo -y

#添加操作用户admin

useradd admin

#修改admin默认密码

echo admin:xxxxxxxxxxxx | chpasswd

#添加jeduser用户sudu权限

#在vim /etc/sudoers文件中root下面添加一行，增加admin的sudo权限

#root    ALL=(ALL)       ALL

admin ALL=(ALL)       ALL

#由于ssh需要依赖于一些key，需要更新key否则ssh无法启动

#Could not load host key: /etc/ssh/ssh_host_rsa_key

#Could not load host key: /etc/ssh/ssh_host_ecdsa_key

#Could not load host key: /etc/ssh/ssh_host_ed25519_key

ssh-keygen -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key

ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ""

ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key 

#安装tcpdump

yum install tcpdump -y

#安装lsof

yum install lsof -y

#安装dstat

yum install dstat -y

#安装scp

yum install openssh-clients

#安装perf

yum install perf -y

#安装sysstat

yum install sysstat -y

#安装perl相关

yum install perl-DBI -y

yum install perl-DBD-MySQL -y

yum install perl-Time-HiRes -y

yum install perl-IO-Socket-SSL

#安装percona-toolkit

yum install perl-TermReadKey -y

yum install perl-Digest-MD5 -y

#官网下载最新版本

#https://www.percona.com/downloads/percona-toolkit/LATEST/

wget https://www.percona.com/downloads/percona-toolkit/3.0.5/binary/redhat/7/x86_64/percona-toolkit-3.0.5-1.el7.x86_64.rpm

rpm -i percona-toolkit-3.0.5-1.el7.x86_64.rpm

#安装percona-xtrabackup

yum install percona-xtrabackup -y

#安装bzip2

yum install bzip2 -y

#安装jq,解析json工具

yum install jq

#安装mysql

wget https://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpm

yum localinstall mysql57-community-release-el7-11.noarch.rpm

yum install mysql-community-server.x86_64 -y

#安装python-setuptools

yum install python-setuptools -y

#安装orzdba

#处理ssh启动脚本

#由于debian和centos文件位置不一致，所以这里直接在centos中加入/etc/init.d/ssh脚本，通过脚本调用/usr/sbin/sshd，确保两个系统调用一致；这样调用模板就可以统一
#以下内容根据需要选择

#ssh脚本内容如下

/usr/sbin/sshd

4 添加证书

#根据需要添加需要的证书，如果不需要就忽略

#切换到admin

su admin

#添加信任证书

echo ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxx >> /home/admin/.ssh/authorized_keys

#修改证书授权文件权限

chmod 644 /home/admin/.ssh/authorized_keys

5. 提交镜像

构建完镜像之后直接获取镜像ID然后提交成基础镜像

提交后可以压缩镜像大小
