1, upload Mysql installation package, Mysql binary package, what installation steps actually not, but there are some configuration requires manual configuration, such as the data directory / data configuration in which, and the installation directory try not to, and the data directory in a folder.
Insert a title outside: If you want to Mysql data directory newly added hard disk, making LVM as follows: If the newly added hard disk is / dev / sdb1,
fdisk dividing partition, create / dev / sda7 sda8 sda9 specify the file system type 8e --- linux lvm, partprobe reset under the partition table, pvcreate / dev / sda7 8, , 9, pvdisplay ---- See all pv native
1, the PV was added VG
vgcreate –s 64M vg01 /dev/sda7 /dev/sda8 /dev/sda9
Without -s 4m size as the default size: Power of 2
See the vgdisplay ----- VG, the number of visible PV, the number of PE, and use of
2, VG divided in LV
lvcreate –L 500M –n le01 /dev/vg01
LV -L specified size, -l specify the LV number LE, -n LV specified name
lvdisplay
lvdisplay -m / dev / vg01 / lv01 ---- View pe mapping relationship in occupied lv
3, for LV production file system, use the mount
mkfs –t ext4 /dev/vg01/lv01
4, after completion of production of the file system, mount / dev / vg1 / lv1 / mysql
There is no other way to upload, you can install Yum source tool, yum -y install lszrz, enter rz automatically pop Explorer page. Click on the appropriate package to upload.
2, currently used is typically a tar.gz package, unzip command tar -zxvf mysql ***. Tar.gz
3, after extracting the file folder, mv mysql **** / usr / local / mysql
4、cd /usr/local/mysql
cp support-files/mysql.server /etc/init.d/mysql.server
After the file is added in the past, you can add boot from the start Services
chkconfig -add mysqld (cp support-files/mysql.server /etc/init.d/mysqld)
5, modified / etc / my, cnf follows:
[mysqld]
basedir=/usr/local/mysql
datadir=/mysql/data
# No configuration data directory, the system will be placed in / var / lib / mysql
socket=/var/lib/mysql/.mysql.sock
character-set-server=utf8
[client]
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8
Kang Rao's my.cnf configuration file separately and then another pass
You can already start with mysql_safe --user = mysql & start mysql daemon to start the service, you can log in using the / usr / local / mysql / bin / mysqladmin -uroot -p mysql database to log the
Now the environment has not been written, edit / etc / pfofile: export PATH = / usr / local / mysql / bin: $ PATH, which is permanent. You can also enter export directly from the command line to collect tax revenues temporarily change my
In the mysql data directory, there are two database files can hang time, to restore sentence structure
Mysql official website tool mysqlfrm
Mysql database table can be derived from the structure of the file table creation statement, database data recovery
command: such as: mysqlfrm --diagnostic /data/mysql_data/aaa/a.frm
this command seems to only recover the table structure, do not know how Data recovery
6, Mysql installation package file has INSTALL_BINARY, wherein the mounting step, now wake up as follows
shell> yum search libaio # search for info
shell> yum install libaio # install library
shell> apt-cache search libaio # search for info
shell> apt-get install libaio1 # install library
shell> groupadd mysql
shell> useradd -r -g mysql mysql

shell> chown -R mysql .

One problem associated with parameters:
innodb_log_file_size parameters, after modification on a Mysql database has been running for a long time, restart Mysql database, error,
报错：Error:log file ./ib_logfile0 is of different size 0 5242880,
Before making changes data is 5M, the system default, commented out, is not enabled, after canceling a comment, start the above error Mysql database was reported.
The final solution: after the data directory, Mysql data directory ib_logfile0, ib_logfile1 delete, then this parameter is enabled, restart the Mysql database, normal start.
Why there would also have two Logfile parameter control innodb_log_files_in_group
