生产环境 xfs filesystem 上安装Mariadb
规划
/dev/sda 安装Linux操作系统，CentOS-6.6
/dev/sdb Mysql数据文件和二进制文件单独放在一块硬盘，磁盘做成LVM逻辑卷方便以后扩充
+--------------------------------------------------------------------------+
| 1、查看磁盘 |
+--------------------------------------------------------------------------+
root@nginx1 ~ > fdisk -l /dev/sdb 数据盘，大小为300G
Disk /dev/sdb: 300.0 GB, 300000000000 bytes
255 heads, 63 sectors/track, 36472 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

+--------------------------------------------------------------------------+
| 2、进行分区，并配置LVM |
+----------------------------------------------------------- ---------------+
1) 进行分区
root@nginx1 ~ > fdisk /dev/sdb
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

root@nginx1 ~ > partprobe /dev/sdb
root@nginx1 ~ > cat /proc/partitions
major minor #blocks name

2) 配置LVM
root@nginx1 ~ > pvcreate /dev/sdb1
Physical volume "/dev/sdb1" successfully created
root@nginx1 ~ > vgcreate mysql-vg /dev/sdb1
Volume group "mysql-vg" successfully created
root@nginx1 ~ > lvcreate -L 250G -n mysql-lv mysql-vg
Logical volume "mysql-lv" created
root@nginx1 ~ > lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
mysql-lv mysql-vg -wi-a----- 250.00g
root@nginx1 ~ >
+--------------------------------------------------------------------------+
| 3、进行格式化===> 格式化为xfs 文件系统 |
+--------------------------------------------------------------------------+
1) 由于默认CentOS内核就支持xfs文件系统，只需要加载模块即可
root@nginx1 ~ > lsmod |grep xfs
root@nginx1 ~ > modprobe xfs
root@nginx1 ~ > lsmod |grep xfs
xfs 1124960 0
exportfs 4236 1 xfs
root@nginx1 ~ >
2) 安装客户端工具包
root@nginx1 ~ > yum -y install xfsprogs
3) 进行格式化
root@nginx1 ~ > mkfs.xfs /dev/mysql-vg/mysql-lv
meta-data=/dev/mysql-vg/mysql-lv isize=256 agcount=4, agsize=16384000 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=65536000, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=32000, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
root@nginx1 ~ >
4) 修改磁盘调度策略为 deadline
root@nginx1 ~ > echo 'deadline' > /sys/block/sdb/queue/scheduler
root@nginx1 ~ > cat /sys/block/sdb/queue/scheduler
noop anticipatory [deadline] cfq
root@nginx1 ~ >
5) 挂载，挂载时禁止atime
root@nginx1 ~ > mkdir /JY
root@nginx1 ~ > mount -o noatime /dev/mysql-vg/mysql-lv /JY/
root@nginx1 ~ > df -HPT
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda5 ext4 22G 1.5G 19G 8% /
tmpfs tmpfs 984M 0 984M 0% /dev/shm
/dev/sda1 ext4 199M 36M 154M 19% /boot
/dev/sda3 ext4 109G 2.3G 101G 3% /usr
/dev/mapper/mysql--vg-mysql--lv xfs 269G 34M 269G 1% /JY
root@nginx1 ~ > mount
/dev/sda5 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/sda3 on /usr type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/mapper/mysql--vg-mysql--lv on /JY type xfs (rw,noatime)
6) 写入fstab
root@nginx1 ~ > echo -e '/dev/mapper/mysql--vg-mysql--lv \t /JY \t xfs \t defaults,noatime \t 0 0' >> /etc/fstab
+--------------------------------------------------------------------------+
| 4、安装Mysql数据库 |
+--------------------------------------------------------------------------+
1) 创建Mysql用户
root@nginx1 ~ > useradd -r mysql -s /sbin/nologin
2) 准备数据目录和二进制存放目录
root@nginx1 ~ > mkdir /JY/{data,binlog}
root@nginx1 ~ > chown -R mysql:mysql /JY/
root@nginx1 ~ > ll /JY/
total 0
drwxr-xr-x 2 mysql mysql 6 Oct 22 10:44 binlog
drwxr-xr-x 2 mysql mysql 6 Oct 22 10:44 data
root@nginx1 ~ >
3) 安装cmkae
root@nginx1 ~ > tar xf cmake-3.0.1.tar.gz
root@nginx1 ~ > cd cmake-3.0.1
root@nginx1 ~/cmake-3.0.1 > ./configure
root@nginx1 ~/cmake-3.0.1 > make && make install
4) 安装数据库
root@nginx1 ~ > tar xf mariadb-10.0.21.tar.gz
root@nginx1 ~ > cd mariadb-10.0.21
root@nginx1 ~/mariadb-10.0.21 > cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

root@nginx1 ~/mariadb-10.0.21 > make && make install

root@nginx1 /usr/local/mysql > chown -R mysql:mysql ./*
root@nginx1 /usr/local/mysql >
root@nginx1 /usr/local/mysql > scripts/mysql_install_db --user=mysql --datadir=/JY/data/
root@nginx1 /usr/local/mysql > cp support-files/my-large.cnf /etc/my.cnf
root@nginx1 /usr/local/mysql > cp support-files/mysql.server /etc/init.d/mysqld
root@nginx1 /usr/local/mysql > chkconfig mysqld --add
root@nginx1 /usr/local/mysql > chkconfig mysqld on
root@nginx1 /usr/local/mysql > echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
root@nginx1 /usr/local/mysql > chmod +x /etc/profile.d/mysql.sh
root@nginx1 /usr/local/mysql > source /etc/profile.d/mysql.sh
root@nginx1 /usr/local/mysql > echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf
root@nginx1 /usr/local/mysql > ldconfig
root@nginx1 /usr/local/mysql > ldconfig -v |grep mysql
/usr/local/mysql/lib:
libmysqlclient.so.18 -> libmysqlclient_r.so.18.0.0
/usr/lib64/mysql:
