1. 从http://www.mysql.com 下载的Mysql安装包 花开2.将mysql的压缩包复制到/usr/local/ 目录# cp mysql-standard-5.0.15-linux
1. 从 下载的Mysql安装包 花开
2.将mysql的压缩包复制到/usr/local/ 目录
# cp mysql-standard-5.0.15-linux-gnu-i686-glibc23.tar.gz /usr/local
3. 解压缩到/usr/ocal/下并改名为mysql,并为了节省空间,删除mysql安装包
# tar xzvf mysql-standard-5.0.15-linux-gnu-i686-glibc23.tar.gz
# mv mysql-standard-5.0.15-linux-gnu-i686-glibc23 mysql
# rm mysql-standard-5.0.15-linux-gnu-i686-glibc23
4.建立mysql组,建立mysql用户并且加入到mysql组中
# groupadd mysql
# useradd mysql -g mysql
5. 覆盖/etc/my.cnf
# cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
6. 进入mysql目录初试化表并且规定用mysql用户来访问。初始化表以后就开始给mysql和root用户设定访问权限
# cd /usr/local/mysql
# ./scripts/mysql_install_db --user=mysql
7. 设定root能访问/usr/local/mysql
# chown -R root .
8. 设定mysql用户能访问/usr/local/mysql/data ,里面存的是mysql的数据库文件.这个目录是在/etc/my.cnf中有配置,,在mysql_install_db时产生
# chown -R mysql data
9. 设定mysql用户能访问/usr/local/mysql/data/mysql下的所有文件
# chown -R mysql data/.
10.设定mysql组能够访问/usr/local/mysql
# chgrp -R mysql .
11. 运行mysql,如果没有问题的话,应该会出现类似这样的提示:
[1] 42264
Starting mysqld daemon with databases from /usr/local/mysql/var
# /usr/local/mysql/bin/mysqld_safe --user=mysql &
如果出现 mysql ended这样的语句,表示Mysql没有正常启动,你可以到log中查找问题,Log文件的通常在/etc/my.cnf中配置。大多数问题是权限设置不正确引起的。
12. 用如下命令修改MYSQL密
# /usr/local/mysql/bin/mysqladmin -u root password yourpassword
13. copy编译目录的一个脚本,设置使mysql每次启动都能自动运行
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
# chmod 700 /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --level 345 mysqld on
14. 启动mysqld服务 拥抱
# service mysqld start

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
