修改mysql配置文件，增加同步参数：
mkdir /mysqllog
主：
server-id=1

BINARY LOGGING

innodb_log_group_home_dir = /mysqllog/
log-bin = /mysqllog/master-bin
expire-logs-days = 7
sync_binlog=1
binlog-ignore-db = mysql
binlog-ignore-db = performance_schema
binlog-ignore-db = information_schema

从：
server-id=2

BINARY LOGGING

innodb_log_group_home_dir = /mysqllog/
log-bin = /mysqllog/slave-bin
expire-logs-days = 7
sync_binlog=1
binlog-ignore-db = mysql
binlog-ignore-db = performance_schema
binlog-ignore-db = information_schema
log_bin_trust_function_creators=TRUE
slave-skip-errors = all #跳过主从复制出现的错误

重启两个数据库

主库新建账号并授权slave
grant replication slave on _._ to ‘sync‘@’%’ identified by ‘lhtx_123456’;
flush privileges;

检测授权结果:
select * from user where host=’%’and user=’sync’\G;
如果Repl_slave_priv项为Y，表示授权成功。

登录主数据库查看master状态
show master status;

注：执行完此步骤后不要再操作主服务器MYSQL，防止主服务器状态值变化

配置从数据库slave
show master status;

找出“File：”，“Position：”

CHANGE MASTER TO MASTER_HOST=’15.3.2.12’, MASTER_USER=’sync’,MASTER_PASSWORD=’lhtx_123456’,MASTER_LOG_FILE=’#######’,MASTER_LOG_POS=########;
注：如果slave处于启动状态，则先执行stopslave命令停止，再执行changemaster to…配置slave，最后执行start slave启动slave。

检测从数据库复制功能状态
show slave status\G;
其中下面两项都必须为yes。

Slave_IO_Running: Yes

Slave_SQL_Running: Yes

MDS上操作：

所有机器都需配置基础环境
service iptables stop
chkconfig iptables off
sed -i ‘/SELINUX/s/enforcing/disabled/‘ /etc/selinux/config

安装编译依赖包
yum install zlib-devel python-devel rpm-build libtool libselinux-devel redhat-rpm-config expect tcl gcc-gfortran tk

安装Lustre Kernel更新Kernel：
rpm -ivh kernel-firmware-2.6.32-431.23.3.el6_lustre.x86_64.rpm
rpm -ivh kernel-devel-2.6.32-431.23.3.el6_lustre.x86_64.rpm
rpm -ivh kernel-2.6.32-431.23.3.el6_lustre.x86_64.rpm

reboo重启
检查内核是否切换为Lustre内核

安装e2fs
rpm -Uvh –nodeps e2fsprogs-libs-1.42.12.wc1-7.el6.x86_64.rpm
rpm -Uvh –nodeps libcom_err-1.42.12.wc1-7.el6.x86_64.rpm

rpm -Uvh e2fsprogs-1.42.12.wc1-7.el6.x86_64.rpm

编译Lustre：
安装Lustre源码包：
rpm -ivh lustre-source-2.5.3-2.6.32_431.23.3.el6_lustre.x86_64.x86_64.rpm
cd /usr/src/lustre-2.5.3/
开始编译：
./configure –with-linux=/usr/src/kernels/2.6.32-431.23.3.el6_lustre.x86_64/ –enable-mpitests=no –
enable-ext4

make

make rpms

安装编译完的Lustre包：
cp -r /root/rpmbuild/RPMS/x86_64 /root/backup/lustre2.5.3/
安装：
cd /root/backup/lustre2.5.3/x86_64/
rpm -ivh lustre-modules-2.5.3-2.6.32_431.23.3.el6_lustre.x86_64.x86_64.rpm
rpm -ivh lustre-osd-ldiskfs-2.5.3-2.6.32_431.23.3.el6_lustre.x86_64.x86_64.rpm
rpm -ivh lustre-2.5.3-2.6.32_431.23.3.el6_lustre.x86_64.x86_64.rpm

把编译生成的rpm包传到各个OSS上，再各个OOS上也需要安装上面的Lustre包

配置Lustre模块和网络
echo “options lnet networks=tcp(eth0)” >> /etc/modprobe.d/lustre.conf
echo “modprobe lustre” >>/etc/rc.local
echo “modprobe lnet” >> /etc/rc.local
重启检查是否加载上
lsmod | grep lustre
lsmod |grep lnet
lctl list_nids

MDS上格式化mdt并挂载：
格式化：
mkfs.lustre –fsname=fclustre –mgs –mdt –index=0 –reformat /dev/sdb
转换普通用户也有可写权限：
tunefs.lustre –param mdt.identity_upcall=NONE /dev/sdb
挂载：
mkdir -p /mnt/fclustre-mdt0
写入开机启动：
echo “mount -t lustre /dev/sdb /mnt/fclustre-mdt0” >> /etc/rc.local
