二进制编译安装mysql

1:解压包及做链接

# tar xvf mysql-5.5.13-linux2.6-i686.tar.gz -C /usr/local

# cd /usr/local

# ln -sv mysql-5.5.13-linux2.6-i686 mysql

# cd mysql

---------------------------------------------------------------

2:增加用户mysql及创建数据库数据存放目录/mydata/data

# groupadd mysql

# useradd -g mysql -s /sbin/nologin -M -r mysql

# mkdir /mydata

# cd /mydata

# mkdir data

# chown -R mysql:mysql /mydata

----------------------------------------------------------------

3:初始化mysql的配置

# cd /usr/local/mysql

# chown mysql:mysql . -R

# scripts/mysql_install_db --user=mysql --datadir=/mydata/data

# chown root . -R

# cp support-files/my-large.cnf /etc/my.cnf

# vim /etc/my.cnf

----------------------------------------------------------------

## 在[mysqld]的字段添加如下一行：

----------------------------------------------------------------

datadir = /mydata/data

----------------------------------------------------------------

4:启动mysql

# cd /usr/local/mysql

# bin/mysqld_safe --user=mysql &

# netstat -nutlp |grep '3306'

----------------------------------------------------------------

5:设置系统使其拥有mysql命令

# vim /etc/profile

----------------------------------------------------------------

##最好在export字段其上添加一行：

----------------------------------------------------------------

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

----------------------------------------------------------------

# . /etc/profile

----------------------------------------------------------------

6:加载库函数

# cd /etc/ld.so.conf.d/

# vim mysql.conf

----------------------------------------------------------------

添加如下一行：

----------------------------------------------------------------

/usr/local/mysql/lib

----------------------------------------------------------------

# ldconfig -v

# ln -sv /usr/local/mysql/include /usr/include/mysql

# ls /usr/include/mysql

----------------------------------------------------------------

7:把mysql加入开机启动

# cd /usr/local/mysql

# cp support-files/mysql.server /etc/init.d/mysqld

# chkconfig --add mysqld

# chkconfig mysqld on

# service mysqld start
