一、编译安装第一个MySQL 5.1.33

cd /opt
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql -s /bin/nologin -d /usr/local/mysql
tar -zxvf mysql-5.1.33.tar.gz
cd mysql-5.1.33/
./configure --prefix=/usr/local/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server  --enable-local-infile --with-plugins=innobase
 
make && make install
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
cp support-files/my-medium.cnf /usr/local/mysql/my.cnf
cd ../

附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下两步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步
无需执行。
①、以mysql用户帐号的身份建立数据表:
/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
②、启动MySQL(最后的&表示在后台运行)
/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &
echo "/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &"  >> /etc/rc.local
ln -s /usr/local/mysql/bin/mysql /sbin/mysql 
ln -s /usr/local/mysql/bin/mysqladmin /sbin/mysqladmin

mysqladmin -u root password 1234  --初始化root密码
mysqladmin -u root -p password 456  --修改root已设置好的密码
mysql -u root -p                 --用新密码连接数据库

添加mysql帐户  
grant all on *.* to 
‘mysql3306‘@‘%‘ identified by ‘mysql3306‘;         --添加用户mysql3306用于远程管理mysql数据库

二、编译安装第二个mysql 5.1.33:
注:可以将第一个mysql的安装文件全部复制过来,为了熟练安装过程,这里就再来重新安装一遍
cd /opt
/usr/sbin/useradd -g mysql mysql3307 -s /bin/nologin -d /usr/local/mysql3307
tar -zxvf mysql-5.1.33.tar.gz
cd mysql-5.1.33/
./configure --prefix=/usr/local/mysql3307/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase
make;make install
chmod +w /usr/local/mysql3307
chown -R mysql3307:mysql /usr/local/mysql3307
chmod -R 777 /usr/local/mysql3307
cp /usr/local/mysql/share/mysql/my-medium.cnf /usr/local/mysql3307/my.cnf
修改配置文件:
port  = 3307                                     --修改端口
socket  = /tmp/mysql3307.sock              --修改sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
port  = 3307
socket  = /tmp/mysql3307.sock

①、以mysql用户帐号的身份建立数据表:
/usr/local/mysql3307/bin/mysql_install_db --basedir=/usr/local/mysql3307 --datadir=/usr/local/mysql3307/data --user=mysql3307
②、启动MySQL(最后的&表示在后台运行)

/bin/sh /usr/local/mysql3307/bin/mysqld_safe --defaults-file=/usr/local/mysql3307/my.cnf &
echo "/bin/sh /usr/local/mysql3307/bin/mysqld_safe --defaults-file=/usr/local/mysql3307/my.cnf &"  >> /etc/rc.local
注:如出现 warning world-writable config file ‘ /usr/local/mysql3307/my.cnf‘ is ignored
解决办法:  chmod 644 /usr/local/mysql3307/my.cnf

mysqladmin -P 3307 -S/tmp/mysql3307.sock  -u root password 1q2w3e  --初始化root密码
mysqladmin -P 3307 -S/tmp/mysql3307.sock  -u root -p password 1q2w3e  --修改root已设置好的密码
/usr/local/mysql3307/bin/mysql -uroot -p -S/tmp/mysql3307.sock
添加mysql帐户  
grant all on *.* to 
‘mysql3307‘@‘%‘ identified by ‘mysql3307‘;         --添加用户mysql3307用于远程管理mysql数据库
