mysql源码编译失败怎么怎么办？

Question

源码编译失败怎么怎么办？ 我怎么删除已经安装的 mysql文件？或者是重新编译一次能覆盖吗？

Answer 1

最近的src.rpm都编译不灵了，所以只能装rpm包了，效果和性能感觉都还不错

# wget http://mysql.oss.eznetsols.org/D ... mysql-5.0.27.tar.gz
# tar xzvf mysql-5.0.27.tar.gz
# cd mysql-5.0.27

配置成功会提示：

MySQL has a Web site at http://www.mysql.com/ which carries details on the
latest release, upcoming features, and other information to make your
work or play with MySQL more productive. There you can also find
information about mailing lists for MySQL discussion.

Remember to check the platform specific part of the reference manual for
hints about installing MySQL on your platform. Also have a look at the
files in the Docs directory.

Thank you for choosing MySQL!

# make
编译的时间可能会比较长，毕竟优化的比较厉害。

# make install

编译安装完成后执行后续操作：
   # useradd mysql   //添加 mysql 用户
   # cd /usr/local/mysql
   # bin/mysql_install_db --user=mysql
   # chown -R root:mysql .   //设置权限，注意后面有一个 "."
   # chown -R mysql /var/lib/mysql   //设置 mysql 目录权限
   # chgrp -R mysql .   //注意后面有一个 "."
   # cp share/mysql/my-huge.cnf /etc/my.cnf
   # cp share/mysql/mysql.server /etc/rc.d/init.d/mysqld   //开机自动启动 mysql。
   # chmod 755 /etc/rc.d/init.d/mysqld
   # chkconfig --add mysqld
   # /etc/rc.d/init.d/mysqld start   //启动 MySQL
   # bin/mysqladmin -u root password "123456789"
   # service mysqld stop   //关闭 MySQL
