安装mysql，安装前准备

如果mysql用户不存在，那么添加mysql用户

groupadd mysql
useradd -g mysql mysql

　　

mysql编译安装

make时间特别长

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-5.1.70yum 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

　　

到此mysql就安装到了/usr/local/mysql路径下，下面开始mysql的配置工作
------------------------------------

安装mysql选项文件

cp support-files/my-medium.cnf /etc/my.cnf

　　

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

　　

配置权限表

chown -R mysql:mysql /usr/local/mysql
/usr/local/mysql/bin/mysql_install_db --user=mysql

　　

启动mysql

给/etc/init.d/mysql 执行权限，然后运行

chmod a+wrx /etc/init.d/mysql
/etc/init.d/mysqld start

　　

mysql初始化配置：

包括密码设置等

export PATH=/usr/local/mysql/bin:$PATH
/usr/local/mysql/bin/mysql_secure_installation　　

在弹出的对话框中要求输入密码：

Enter current password for root (enter for none):

默认打回车，然后重新设置root密码:

Set root password? [Y/n] y

Disallow root login remotely? [Y/n] n

Remove test database and access to it? [Y/n] n

Reload privilege tables now? [Y/n] y

至此，Mysql运行成功
