（4）linux下安装配置Mysql

1）创建用户和组
groupadd mysql
useradd mysql -g mysql -M -s /sbin/nologin

2）下载软件
3）编译安装
./configure \
--prefix=/application/mysql5.1.72 \
--with-unix-socket-path=/application/mysql5.1.72/tmp/mysql.sock \
--localstatedir=/application/mysql5.1.72/data \
--enable-assembler \
--enable-thread-safe-client \
--with-mysqld-user=mysql \
--with-big-tables \
--without-debug \
--with-pthread \
--enable-assembler \
--with-extra-charsets=complex \
--with-readline \
--with-ssl \
--with-embedded-server \
--enable-local-infile \
--with-plugins=partition,innobase \
--with-mysqld-ldflags=-all-static \
--with-client-ldflags=-all-static 

创建mysql.install 
文件，将上述编译配置复制到文件中，进入到mysql包目录，
编译安装：
cat mysql.install | bash

错误：
checking for termcap functions library... configure: error: No curses/termcap library found

yum安装：
yum install ncurses-devel

make && make install

创建软链接
ln -s /application/mysql5.1.72/ /application/mysql

4）
拷贝配置文件：
cp my-small.cnf /etc/my.cnf 

创建msyql数据句文件
mkdir /application/mysql/data -p

授权
chown -R mysql.mysql /application/mysql

初始化数据库
/application/mysql/bin/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql

cp mysql.server.sh /etc/init.d/mysqld

启动mysql
cd /application/mysql ; /application/mysql/bin/mysqld_safe &

cd /application/mysql ; /application/mysql/bin/mysqld_safe —skip-grant-table &
忽略授权表，用于修改密码

将mysql
添加到pah路径中
vim /etc/profile
. /etc/profile

命令行执行
mysql
进入到mysql的交互模式

脚本文件启动mysql
cp mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld 
chkconfig --add mysqld
chkconfig mysqld on

vi /etc/init.d/mysqld
编辑下面两行：
basedir=/application/mysql/
datadir=/application/mysql/data

杀死mysql
进程
pkill mysqld

5）添加密码
/application/mysql/bin/mysqladmin -u root password 'oldboy123'

登录：
mysql -uroot -poldboy123

select version();
select user();
