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

http://dev.mysql.com/downloads/mysql/5.6.html#downloads

这是mysql官网地址，你可以根据你的内核版本下载相应的msyql版本安装包，如：

MySQL-client-5.6.31-1.el7.x86_64.rpm

MySQL-server-5.6.31-1.el7.x86_64.rpm

下载好上述两个安装包后执行安装命令就可以了：

rpm -ivh MySQL-client-5.6.31-1.el7.x86_64.rpm

rpm -ivh MySQL-server-5.6.31-1.el7.x86_64.rpm

注意：安装之前要确认你的主机目前有没有默认安装的mysql版本，如果有，先删除就可以了。

你试着再终端输入：sudo /etc/init.d/mysql start

要是你说的只是解压就运行的话，主要还得看你的安装目录，再在终端输入上面类似的命令，比如改下文件夹（/etc/init.d/），就是该成你在哪里解压的文件夹。
