从MySQL5.5 开始就要用cmake安装，本次安装的版本为mysql-5.5.22.tar.gz

手册中提到的安装方法：
To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/local/mysql//bin/mysqladmin -u root password ‘new-password‘ /usr/local/mysql//bin/mysqladmin -u root -h localhost password ‘new-password‘ Alternatively you can run: /usr/local/mysql//bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr/local/mysql/ ; /usr/local/mysql//bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd /usr/local/mysql//mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/local/mysql//scripts/mysqlbug script!
默认的mysql安装目录
shell> groupadd mysql shell> useradd -r -g mysql mysql # Beginning of source-build specific instructions shell> tar zxvf mysql-VERSION.tar.gz shell> cd mysql-VERSION shell> cmake . shell> make shell> make install # End of source-build specific instructions # Postinstallation setup shell> cd /usr/local/mysql shell> chown -R mysql . shell> chgrp -R mysql . shell> scripts/mysql_install_db --user=mysql shell> chown -R root . shell> chown -R mysql data # Next command is optional shell> cp support-files/my-medium.cnf /etc/my.cnf shell> bin/mysqld_safe --user=mysql & # Next command is optional shell> cp support-files/mysql.server /etc/init.d/mysql.server
修改默认密码（默认无密码）：
use mysql; update user set password=password(‘123456‘) where user=‘root‘ flush privileges;
