Linux 上通过rpm安装mysql

安装mysql之前要remove掉系统自带的mysql：

rpm -qa | grep "MySQL*"    和rpm -qa | grep mysql  要确保卸载干净

rpm -e MySQL-server-5.1.74-1.el6.x86_64.rpm --nodeps

mysql这里使用rpm 安装:

安装包：MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tar

tar xf MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tar

解压出：

[root@vm-mha-slave02 mysql_install_packet]# ll

先创建用户：

groupadd mysql                        --创建mysql用户组

useradd -M -s  /sbin/nologin mysql -g mysql  --这里创建的mysql不能登录没有家目录

 

rpm逐一安装：

rpm -ivh  MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm

rpm -ivh MySQL-devel-5.6.26-1.linux_glibc2.5.x86_64.rpm

rpm -ivh MySQL-embedded-5.6.26-1.linux_glibc2.5.x86_64.rpm

rpm -ivh MySQL-shared-5.6.26-1.linux_glibc2.5.x86_64.rpm

rpm -ivh MySQL-shared-compat-5.6.26-1.linux_glibc2.5.x86_64.rpm

rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm

这里test不用安装了！

 

更改数据目录：

mkdir /mysqldata

将rpm默认安装的数据目录下的文件都移动到新目录下面：

mkdir -p /mysqldata/

mv /var/lib/mysql/* /mysqldata/

cd /mysqldata

mkdir slowlog

mkdir binlog

mkdir relaylog

mkdir tmpdata

mkdir general_log

chown -R mysql:mysql /mysqldata

 

更改my.cnf文件:

使用下列内容替换原有/etc/my.cnf内容，具体参数要根据应用需求和服务器情况进行调整：

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

#使用本配置之前请在数据目录新建一下目录: tmpdata  binlog  relaylog general_log  slowlog ,并且赋予mysql用户权限!

添加mysql服务到开机启动：

chkconfig --add mysql

chkconfig --levels 235 mysql on

最后vi /etc/init.d/mysql  修改basedir和datadir为下面内容：

basedir=/usr

datadir=/mysqldata

 

service mysql start

cat /root/.mysql_secret

mysql -uroot -p'5P19xzxfIPUWyxwR'   --这个密码为mysql_secret里面的

SET PASSWORD = PASSWORD('mysteel');

flush privileges;

drop database test;
