创建mysql用户
groupadd mysql
useradd -g mysql mysql
mysql编译安装
wget http://downloads.mysql.com/archives/mysql-5.1/mysql-5.1.70.tar.gz tar -zxvf mysql-5.1.70.tar.gz cd mysql-5.1.70 yum install ncurses ncurses-devel ./configure '--prefix=/usr/local/mysql' '--without-debug' '--with-charset=utf8' '--with-extra-charsets=all' '--enable-assembler' '--with-pthread' '--enable-thread-safe-client' '--with-mysqld-ldflags=-all-static' '--with-client-ldflags=-all-static' '--with-big-tables' '--with-readline' '--with-ssl' '--with-embedded-server' '--enable-local-infile' '--with-plugins=innobase' make make install
下面开始mysql的配置工作
1.安装mysql选项文件
cp support-files/my-medium.cnf /etc/my.cnf
2.mysql设置开机自启动
cp -r support-files/mysql.server /etc/init.d/mysqld /sbin/chkconfig --del mysqld /sbin/chkconfig --add mysqld
3.配置权限表
chown -R mysql:mysql /usr/local/mysql /usr/local/mysql/bin/mysql_install_db --user=mysql
可能出现的问题：
130925 10:08:28 [Warning] '--skip-locking' is deprecated and will be removed
解决办法：
vim /etc/my.cnf
找到：skip-locking
改为：skip-external-locking
WARNING: The host 'xxx' could not be looked up with resolveip.
解决办法,增加host：
vim /etc/host
127.0.0.1 xxx
4.启动mysql
sudo sh /etc/init.d/mysqld start
开机启动mysql
chmod 755 /etc/init.d/mysqld chkconfig --add mysqld chkconfig --level 345 mysqld on chkconfig --list mysqld
mysql初始化配置：
vim /etc/profile
最下面写入：
PATH=/usr/local/mysql/bin:$PATH
初始化配置mysql
/usr/local/mysql/bin/mysql_secure_installation
mysql如何导入旧的数据：
直接拷贝数据库文件夹到数据目录下然后执行
/usr/local/mysql/bin/mysqladmin -u root -p flush-tables
