Mysql+heartbeat+nfs do high Availability

First , the Environment preparation node two
node1:10.10.10.202
node2:10.10.10.203
Server for NFS:
node3:10.10.10.204
System Environment CentOS release 6.5 (Final)
second, create a shared directory of MySQL on the NFS server
Mkdir/data
Vim/etc/exports
/data 10.10.10.0/24 (rw,no_root_squash)
re-export the file system
Exportfs-rav
look at the client and try to mount
showmount-e 10.10.10.204
mount-t NFS 10.10.10.204:/data/data
Add the MySQL user group and the user (the ID of the MySQL user and group to keep each node is consistent OH)
groupadd-r-G MySQL
useradd-u 250-g MySQL mysql
setfacl-m U:mysql:rwx/data
Node1:
groupadd-r-G MySQL
useradd-u 250-g MySQL mysql
Node2:
groupadd-r-G MySQL
useradd-u 250-g MySQL mysql
Node1 and Node2:
Tar xf mariadb-10.0.28-linux-glibc_214-x86_64.tar.gz-c/usr/local/
ln-sv mariadb-10.0.28-linux-x86_64 MySQL
chown Root.mysql.-R
Mkdir/data/{database,binlog}
chown-r Mysql.mysql/data
Initializing the database
mariaDB10.0.28 need to install version 2.14 of glibc and 6.5 is 2.12
error message:
./bin/my_print_defaults:/lib64/libc.so.6:version ' glibc_2.14 ' not found (required by./bin/my_print_defaults)
Workaround:
Upgrade glibc
wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
Tar zxvf glibc-2.14.tar.gz
CD glibc-2.14

Workaround:
Upgrade GCC
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.0/gcc-4.8.0.tar.bz2
TAR-JXVF gcc-4.8.0.tar.bz2
CD gcc-4.8.0

Workaround:
Yum Install gcc-c++
Make Install
determine the path to the newly installed GCC, usually by default under/usr/local/bin.
ls/usr/local/bin | grep gcc
viewing the GCC version can be used gcc-v
add a new gcc to the optional, the last third is the name, the penultimate parameter is the new GCC path, the final parameter 40 is the priority, and the new version is automatically used after setting a larger one.
update-alternatives--INSTALL/USR/BIN/GCC GCC/USR/LOCAL/BIN/I686-PC-LINUX-GNU-GCC
Start with strings/usr/lib64/libstdc++.so.6 | grep glibcxx to view supported versions
ln-sf/usr/local/lib64/libstdc++.so.6.0.18/usr/lib64/libstdc++.so.6
Copy the MySQL startup scripts and configuration files
Mkdir/etc/mysql
CP support-files/my-large.cnf/etc/mysql/my.cnf
CP Support-files/mysql.server/etc/rc.d/init.d/mysqld
chmod +x/etc/rc.d/init.d/mysqld
chkconfig--add mysqld
chkconfig mysqld off

DataDir =/data/database

Log-bin=/data/binlog/master-bin
Start the service
/etc/init.d/mysqld Start
