tar zxvf mysql-5.5.3-m3.tar.gz

cd mysql-5.5.3-m3/

./configure --prefix=/usr/local/mysql2/ --with-tcp-port=3307 --with-unix-socket-path=/tmp/mysql2.sock --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg

make && make install

cp /usr/local/mysql2/share/mysql/my-medium.cnf /etc/my2.cnf

cp /usr/local/mysql2/share/mysql/mysql.server /etc/init.d/mysql2

修改服务文件

vi /etc/rc.d/init.d/mysql2

将引用的配置文件名称由my.cnf改为当前要使用的配置文件my2.cnf，将my.cnf改成my2.cnf

# Try to find basedir in /etc/my.cnf

conf=/etc/my.cnf

print_defaults=

if test -r $conf

then

在$bindir/mysqld_safe中添加--defaults-file=/etc/my2.cnf

修改成下面

# may be overwritten at next upgrade.

$bindir/mysqld_safe --defaults-file=/etc/my2.cnf --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &

保存。

初始化数据库

/usr/local/mysql2/bin/mysql_install_db --defaults-file=/etc/my2.cnf --basedir=/usr/local/mysql2/ --datadir=/usr/local/mysql2/var/ --user=mysql

chown -R mysql /usr/local/mysql2/var

chgrp -R mysql /usr/local/mysql2/.

chmod 755 /etc/init.d/mysql2

chkconfig --level 345 mysql2 on

service mysql2 start

至此安装完毕，可以启动一下，看是否有该进程

netstat -tlnap | grep mysql

/usr/local/mysql2/bin/mysql -uroot -p --socket=/tmp/mysql2.sock

change master to master_host='0.0.0.0', master_user='replication',master_password='00000', master_log_file='mysql-bin.000005', master_log_pos=107,MASTER_PORT=3306;

要指定端口，要不用的是本实例默认端口。
