MySQL migration in CentOS 5.6

This week, two sets of EMC storage are migrated, and several intranet database servers are attached to the storage space. You need to migrate the stored database to the server. The specific migration steps are as follows:

I. Environment:

1. original database server: 172.28.29.21 (Mount EMC to the/sandata directory)

2. Database Server: 10.20.220.107

II. Specific ideas:

1. Run NFS on 10.20.220.107 and mount/data/db to 172.28.29.21.

2. Mount/data/db of 10.20.220.107 to/data/db on 172.28.29.21

3. copy all files in the mysql database directory DB under the/sandata directory to/data/db on 172.28.29.21.

4. Install the mysql database on 10.20.220.107. www.bkjia.com directs the database path to/data/db.

5. Test

Iii. Implementation steps

1. The first three steps are simple. I will not talk about them here. Next we will install the mysql database.

A. Install ncurses-devel first

[Root @ localhost ~] # Yum install ncurses-devel

B. Install mysql

[Root @ localhost ~] # Useradd mysql-s/sbin/nologin

[Root @ localhost ~] # Tar-zxvf mysql-5.1.54.tar.gz
[Root @ localhost ~] # Cd mysql-5.1.54

[Root @ localhost mysql-5.1.54] #. /configure -- prefix =/usr/local/mysql -- with-mysqld-user = mysql -- with-extra-charsets = all -- with-charset = utf8 -- with-unix-socket- path =/usr/local/mysql/var/mysql. sock -- enable-thread-safe-client -- with-plugins = innobase

Note: This error may be reported in this step:

Config. status: executing libtool commands
/Bin/rm: cannot remove 'libtoolt': No such file or directory
Config. status: executing default commands
Solution:

Run the following command before executing./configure:
# Autoreconf -- force -- install
# Libtoolize -- automake -- force
# Automake -- force -- add-missing

Execute again:

[Root @ localhost mysql-5.1.54] #. /configure -- prefix =/usr/local/mysql -- with-mysqld-user = mysql -- with-extra-charsets = all -- with-charset = utf8 -- with-unix-socket- path =/usr/local/mysql/var/mysql. sock -- enable-thread-safe-client -- with-plugins = innobase

[Root @ localhost mysql-5.1.54] # make & make install

# Copy a my. cnf file to/etc, and I will post the content later

[Root @ localhost data] # chown mysql/data/db

[Root @ localhost db] # chmod 777/data/db

[Root @ localhost ~] #/Usr/local/mysql/bin/mysql_install_db -- user = mysql -- datadir =/data/db

[Root @ localhost db] #/usr/local/mysql/bin/mysqld_safe &
