MySQL 5 on Linux手动安装方法
1. 下载"mysql-standard-5.0.27-linux-i686-icc-glibc23.tar.gz",推荐ICC版本,据称比GCC性能提高10-20%
2. 复制到/usr/local/,解压:tar zxvf mysql-standard-5.x....tar.gz
3. 添加用户和组mysql:
groupadd mysql
useradd -g mysql mysql
4. 创建符号连接:/usr/local # ln -s mysql-standard-5.x... mysql
5. cd mysql,当前目录改为/usr/local/mysql/
6. 运行脚步初始化数据库:./scripts/mysql_install_db --user=mysql
7. 设置权限:
/usr/local/mysql # chown -R root .
/usr/local/mysql # chown -R mysql data
/usr/local/mysql # chgrp -R mysql
8. 根据需要创建并修改/etc/my.cnf,参考配置:
[mysqld]
# 设置默认为INNODB表,支持事务:
default-storage-engine=INNODB
# 设置默认的字符集:
default-character-set=utf8
# 禁用bdb:
skip-bdb
9. 启动MySQL:
/usr/local/mysql/bin # ./mysqld_safe --user=mysql &
10. 初始化root口令:
/usr/local/mysql/bin # ./mysqladmin -u root -p password "password-of-root"
Enter password: <输入旧口令,直接按Enter>
11. 以root登录创建数据库:
/usr/local/mysql # ./mysql -u root -p
Enter password: password-of-root
创建一个新用户:
mysql> create user test identified by 'test-password';
创建一个新数据库:
mysql> create database testdb;
赋予test用户从localhost访问testdb的权限:
mysql> grant all on testdb.* to test@localhost;
停止MySQL服务器:
/usr/local/mysql/bin # ./mysqladmin -u root -p shutdown
Enter password: password-of-root
STOPPING server from pid file /usr/local/mysql/data/debian.pid
