Linux下安装MySQL多实例作为数据备份服务器实现多主到一从多实例的备份

这篇文章主要为大家详细介绍了Linux下安装MySQL多实例作为数据备份服务器实现多主到一从多实例的备份，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
[注] 添加mysql组和用户 
#groupadd mysql 
#useradd -g mysql mysql 
[注] 解包到/usr/local 
# tar -xzf mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz -C /usr/local 
[注] 建立软链接，方便操作（此处给此连接命名为mysql001，也可为其它的名字） 
#cd /usr/local 
#ln -s mysql-standard-5.0.15-linux-i686-glibc23 mysql001 
#cd mysql001 
#scripts/mysql_install_db 
#chown -R root . 
#chown -R mysql data 
#chgrp -R mysql . 
[注] 复制data，以供单版本多实例分配 
#cp -a data data_1 
#cp -a data data_2 
[注] 添加多实例配置文件 
#cd /usr/local/mysql001/bin 
#cat >my_multi.cnf 
[注] 以下是my_multi.cnf的配置信息，可依此复制 
[mysqld_multi] 
mysqld = /usr/local/mysql001/bin/mysqld_safe 
mysqladmin = /usr/local/mysql001/bin/mysqladmin 
user = root 
password = root 
[mysqld1] 
socket = /tmp/mysql_001.sock 
port = 3301 
pid-file = /usr/local/mysql001/data_1/hostname.pid 
datadir = /usr/local/mysql001/data_1 
log = /usr/local/mysql001/data_1/hostname.log 
user = mysql 
# slave setting 
server-id = 2 
master-host = 192.168.1.85 
master-port = 3306 
master-user = backup 
master-password = 123456 
replicate-do-db = gs_database 
replicate-do-db = gs_log 
master-connect-retry=30 
[mysqld2] 
socket = /tmp/mysql_5_2.sock 
port = 3302 
pid-file = /usr/local/mysql001/data_2/hostname.pid 
datadir = /usr/local/mysql001/data_2 
log = /usr/local/mysql001/data_2/hostname.log 
user = mysql 
# slave setting 
server-id = 3 
master-host = 192.168.1.69 
master-port = 3306 
master-user = backup 
master-password = 123 
replicate-do-db = gs_databaes 
replicate-do-db = gs_log 
master-connect-retry=30 

代码如下:

 
#vi /etc/profile # 添加系统环境变量。 
export MYSQL_HOME=/usr/local/mysql001/bin 
export PATH=$PATH:$MYSQL_HOME 

代码如下:

 
vi /etc/rc.local 
# 添加 
mysqld_multi --defaults-extra-file=/usr/local/src/mysql_dir/bin/my_multi.cnf start 1,2
