oracle有克隆安装,事实上mysql/mariadb相似。仅仅需简单几步就能够直接在异机直接启动.
环境:
node01安装完毕的mariadb;
node02一个新机器
如今将node01克隆到node02机器
--1.node02准备环境
#yum remove mysql-libs
#yum -y install cmake gcc gcc-c++ autoconf automake zlib* libxml*
ncurses ncurses-devel libtool-ltdl-devel* make bison bison-devel libaio
#groupadd mysql && useradd -g mysql mysql -s /sbin/nologin && echo 'mysql01!@#' |passwd --stdin mysql
#vi + /etc/security/limits.conf
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
--2.node01正常关闭数据库
# mysqlshutdownv.sh
mysql port is 33107
close mysql service
--------------------------------------------
mysql shutdown....Wait a minute...
****MYSQL SUCESS CLOSE****
---3.node01打包
tar czvf mysql.tar.gz /data/
--4.传输到node02
# scp -r -p -P 22 /root/mysql.tar.gz root@192.168.50.160:/backup
The authenticity of host '192.168.50.160 (192.168.50.160)' can't be established.
RSA key fingerprint is 74:5d:47:c0:f8:cf:e7:bb:8c:76:94:4f:0d:6b:ea:c8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.50.160' (RSA) to the list of known hosts.
root@192.168.50.160's password:
mysql.tar.gz 100% 131MB 43.6MB/s 00:03
--5.解压和改动权限
#cd /backup
# tar zxvf mysql.tar.gz -C /data/
# ls /data/
data
--移动文件夹到上一层
# cd /data/data/ && mv mysql/ ../ && mv ocpyang/ ../ && ls /data/data/ && ls /data/mysql/ && ls /data/ocpyang
# rm -rf /data/data
#chown -R mysql /data/mysql && chgrp -R mysql /data/mysql
--6.链接必要文件
##链接文件
#ln -fs /data/mysql/my.cnf /etc/my.cnf; ll /etc/my.cnf
#cd /data/mysql/&& cp support-files/mysql.server /etc/init.d/mysql && chkconfig mysql on
--7.改动my.cnf文件
#vi /etc/my.cnf
:%s/node01/node02/g
--8.改动环境变量
# vi ~/.bash_profile
#ocpyang set
alias date='date "+%Y-%m-%d %H:%M:%S" '
alias mysql="mysql -hlocalhost -uroot -ppassword --auto-rehash --prompt="u@node02 R:m:s>" "
alias errorlog="cat /data/mysql/mysql_logs/error_log/error.log"
alias mycnf="cd /data/mysql"
export PATH=/data/mysql/scripts:$PATH
#source ~/.bash_profile
#chmod 755 /data/ocpyang/*
#echo "export PATH=/data/ocpyang:$PATH">>~/.bash_profile
#source ~/.bash_profile
--9.启动mysql
#chown -R mysql /data/mysql; chgrp -R mysql /data/mysql
#/data/mysql/bin/mysqld_safe --datadir='/data/mysql/data' &
# mysql
