安装第二个MySQL数据库
（1）清理配置信息
[root@localhost bin]# cd /workspace/mysql-5.5.32
[root@localhost mysql-5.5.32]# make clean
[root@localhost mysql-5.5.32]# rm -rf CMakeCache.txt
（2）创建所需要的文件目录
[root@localhost mysql-5.5.32]# cd /usr/local/
[root@localhost local]# mkdir mysql3307
[root@localhost local]# cd mysql3307/
[root@localhost mysql3307]# mkdir data
[root@localhost mysql3307]# mkdir etc
（3）配置第二个实例的编译信息
[root@localhost bin]# cd /workspace/mysql-5.5.32
[root@localhost mysql-5.5.32]# cmake \
> -DCMAKE_INSTALL_PREFIX=/usr/local/mysql3307 \
> -DMYSQL_DATADIR=/usr/local/mysql3307/data \
> -DSYSCONFDIR=/usr/local/mysql3307/etc \
> -DWITH_MYISAM_STORAGE_ENGINE=1 \
> -DWITH_INNOBASE_STORAGE_ENGINE=1 \
> -DWITH_MEMORY_STORAGE_ENGINE=1 \
> -DWITH_READLINE=1 \
> -DMYSQL_UNIX_ADDR=/tmp/mysqld3307.sock \
> -DMYSQL_TCP_PORT=3307 \
> -DENABLED_LOCAL_INFILE=1 \
> -DWITH_PARTITION_STORAGE_ENGINE=1 \
> -DEXTRA_CHARSETS=all \
> -DDEFAULT_CHARSET=utf8 \
> -DDEFAULT_COLLATION=utf8_general_ci
（4）编译安装
[root@localhost mysql-5.5.32]# make & make install
（5）配置第二个MySQL实例
[root@localhost mysql-5.5.32]# cd /usr/local/mysql3307
[root@localhost mysql3307]# chown -R mysql:mysql .
[root@localhost mysql3307]# cp support-files/my-medium.cnf /usr/local/mysql3307/etc/my.cnf
[root@localhost mysql3307]# vi /usr/local/mysql3307/etc/my.cnf
添加 datadir=/usr/local/mysql3307/data
default-storage-engine=MyISAM
[root@localhost mysql3307]# cd /usr/local/mysql3307/scripts/
[root@localhost scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql3307 --datadir=/usr/local/mysql3307/data &
[root@localhost scripts]# cd /usr/local/mysql3307/bin
[root@localhost bin]# ./mysqld_safe --user=root
131016 20:40:27 mysqld_safe Logging to '/usr/local/mysql3307/data/localhost.localdomain.err'.
131016 20:40:27 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql3307/data
查看服务是否启动成功
[root@localhost bin]# netstat -tlnap | grep mysql
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 29147/mysqld
tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 7447/mysqld
登录MySQL并修改root用户密码
[root@localhost bin]# ./mysqladmin -uroot password 'eisoo.com123'
[root@localhost bin]# ./mysql -uroot -peisoo.com123
