mariadb克隆

Posted 2020-06-10 Angus_yang

oracle有克隆安装,其实mysql/mariadb类似，只需简单几步就可以直接在异机直接启动.
环境:
node01安装完成的mariadb;
node02一个新机器
现在将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 '[email protected]#' |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  [email protected]:/backup

--5.解压和修改权限


#cd /backup

# tar zxvf mysql.tar.gz -C /data/

# ls /data/
data

--移动目录到上一层
# 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.修改my.cnf文件
#vi /etc/my.cnf

:%s/node01/node02/g




--8.修改环境变量

# vi ~/.bash_profile

#ocpyang set
alias date='date "+%Y-%m-%d %H:%M:%S" '
alias  mysql="mysql -hlocalhost -uroot -ppassword --auto-rehash --prompt=\"\[email protected] \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
