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
