3. InstallMySQL using source code
cd /home1/mysql
1. Compile and install cmake,
wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz
tar xvf cmake-2.8.5.tar.gz
cd cmake-2.8.5
./bootstrap
make
make install
2. Compile and install mysql-5.5.15 (Directory: /home1/mysql/mysql-service)
wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.15.tar.gz/from/http://mirror.khlug.org/mysql/
tar xvf mysql-5.5.15.tar.gz
cd mysql-5.5.15
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
cmake -DCMAKE_INSTALL_PREFIX=/home1/mysql/mysql-service \
-DMYSQL_UNIX_ADDR=/home1/mysql/mysql-service/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk,gb2312 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/home1/mysql/mysql-service/data \
-DMYSQL_USER=mysql
make
make install
3. MySQL configuration
chmod +w /home1/mysql/mysql-service
chown -R mysql:mysql /home1/mysql/mysql-service
mkdir -p /home1/mysql/mysql-service/data/
mkdir -p /home1/mysql/mysql-service/log/
cd support-files/
cp my-large.cnf /home1/mysql/mysql-service/my.cnf
cp mysql.server /etc/init.d/mysqld
/home1/mysql/mysql-service/scripts/mysql_install_db \
--defaults-file=/home1/mysql/mysql-service/my.cnf \
--basedir=/home1/mysql/mysql-service \
--datadir=/home1/mysql/mysql-service/data \
--user=mysql
chmod +x /etc/init.d/mysqld
vi /etc/init.d/mysqld（edit this file，find and edit the variables, if there no these variable add them）
basedir=/home1/mysql/mysql-service
datadir=/home1/mysql/mysql-service/data
4. Add them into bootup：
chkconfig --add mysqld
chkconfig --level 345 mysqld on
5. start mysql service：
service mysqld start
6.Set password：
/home1/mysql/mysql-service/bin/mysqladmin password [new-password]
7. Many programs call mysql.sock from /var/lib/mysql/mysql.sock:
mkdir -p /var/lib/mysql
ln -s /var/lib/mysql/mysql.sock /home1/mysql/mysql-service/tmp/mysql.sock
4. InstallMySQL using compressed TAR archive without Installation
1. Download compressed tar archive mysql file
cd /home1/mysql
tar xvf mysql-5.5.16-linux2.6-x86_64.tar.gz
cp -r mysql-5.5.16-linux2.6-x86_64/ mysql
mkdir -p /home1/mysql/mysql/tmp
groupadd mysql
useradd -g mysql mysql
cd /home1/mysql/mysql
ln -s /home1/mysql/mysql/bin/mysql /usr/bin/
chown -R mysql .
chgrp -R mysql .
scripts/mysql_install_db --user=mysql
chown -R root .
chown -R mysql data
cp support-files/my-medium.cnf /etc/my.cnf
vi my.cnf
basedir=/home1/mysql/mysql
datadir=/home1/mysql/mysql/data
socket = /home1/mysql/mysql/tmp/mysql.sock
innodb_data_home_dir = /home1/mysql/mysql/data/
/home1/mysql/mysql/bin/mysqld_safe --user=mysql & --start mysqld service
Error：
110915 18:01:50 [ERROR] Can't start server : Bind on unix socket: Permission denied
110915 18:01:50 [ERROR] Do you already have another mysqld server running on socket: /home1/mysql/mysql/tmp/mysql.sock ?
Solution： chmod 777 /home1/mysql/mysql/tmp/
/home1/mysql/mysql/bin/mysqladmin -uroot -p shutdown -- shut down mysql
Error：
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Solution：
-- mysqladmin call mysql.sock from /tmp/mysql.sock default
ln -s /home1/mysql/mysql/tmp/mysql.sock /tmp/mysql.sock
bin/mysqladmin -uroot password [password]
2. Add mysql service into bootup
cp support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod 700 /etc/init.d/mysqld
chkconfig –add mysqld
chkconfig –level 345 mysqld on
