linux下mysql解压后怎么安装

shell>groupadd mysql

shell>useradd -r -g mysql mysql

shell>cd /usr/local

shell>tar zxvf mysql-5.5.32-linux2.6-x86_64.tar.gz

shell>mv mysql-5.5.32-linux2.6-x86_64 /usr/local/mysql3309

shell>cd /usr/local/mysql3309

shell>chown -R mysql .

shell>chgrp -R mysql .

2

shell>cat my3309.cnf

#/usr/local/mysql3309下新建my3309.cnf配置文件，内容复制my3308.cnf

shell>mkdir /usr/local/mysql3309/logs

shell>mkdir /usr/local/mysql3309/bin-log

shell>chown -R mysql.mysql .

shell>scripts/mysql_install_db --user=mysql --defaults-file=/usr/local/mysql3309/my3309.cnf

(启动mysql）

shell>bin/mysqld_safe --defaults-file=/usr/local/mysql3309/my3309.cnf --user=mysql >/dev/null 2>&1 &

（进入mysql）

shell>bin/mysql --defaults-file=/usr/local/mysql3309/my3309.cnf

4

无法启动或进入：

查看日志shell>tail -f /usr/local/mysql3309/logs/mysql3309.log

END

注意事项

解压缩版的mysql可直接运行，执行时需指定my.cnf文件

注意添加--defaults-file=/usr/local/my3309.cnf命令

由于在my.cnf文件中指定了mysql.sock的位置，为了避免多个mysql同时读取/tmp/mysql.sock文件，在启动时指定读取的sock文件位置： --socket=/tmp/mysql3307.sock

到mysql官网下载mysql编译好的二进制安装包

解压32位安装包:

进入安装包所在目录，执行命令：tar mysql-5.6.17-linux-glibc2.5-i686.tar.gz

复制解压后的mysql目录到系统的本地软件目录:

执行命令：cp mysql-5.6.17-linux-glibc2.5-i686 /usr/local/mysql -r

注意：目录结尾不要加/

添加系统mysql组和mysql用户：

执行命令：groupadd mysql和useradd -r -g mysql mysql

安装数据库：

进入安装mysql软件目录：执行命令 cd /usr/local/mysql

修改当前目录拥有者为mysql用户：执行命令 chown -R mysql:mysql ./

安装数据库：执行命令 ./scripts/mysql_install_db --user=mysql

修改当前目录拥有者为root用户：执行命令 chown -R root:root ./

修改当前data目录拥有者为mysql用户：执行命令 chown -R mysql:mysql data

到此数据库安装完毕
