Mysql那些事儿之（一）mysql的安装

一、Linux下安装Mysql数据库

首先下载Linux的Mysql安装包

mysql-5.0.85.tar.tar

将下载好的安装包上传至Linux的 /usr/sid/mysql 目录

然后继续如下操作：

安装步骤：

--进入Mysql的安装目录

cd /usr/sid/mysql

--添加一个Mysql组

groupadd mysql

--在Mysql组里添加一个Mysql用户

useradd -g mysql mysql

安装：

--解压Mysql安装包

tar zxvf mysql-5.0.85.tar.tar

--进入mysql-5.0.85目录

cd mysql-5.0.85

--配置Mysql的安装路径与相关参数

./configure --prefix=/usr/local/sunnyboysac/mysql -with-extra-charsets=gbk -with-extra-charsets=all -with-named-curses-libs=/usr/lib/libncurses.so.5 -with-innodb

--编译

make

--安装

make install

配置步骤：

--进入mysql解压的目录

cd mysql-5.0.85

--拷贝文件

cp support-files/my-large.cnf /etc/my.cnf

vi /etc/my.cnf

修改内容

添加一行

default-storage-engine=INNODB

并把innodb相关的注释（#）去掉

改写部分修改后的形式如下

#bdb_max_lock = 100000

default-storage-engine=INNODB

# Uncomment the following if you are using InnoDB tables

innodb_data_home_dir = /usr/local/eetrust/mysql/var/

innodb_data_file_path = ibdata1:10M:autoextend

innodb_log_group_home_dir = /usr/local/eetrust/mysql/var/

innodb_log_arch_dir = /usr/local/eetrust/mysql/var/

# You can set .._buffer_pool_size up to 50 - 80 %

# of RAM but beware of setting memory usage too high

innodb_buffer_pool_size = 256M

innodb_additional_mem_pool_size = 20M

# Set .._log_file_size to 25 % of buffer pool size

innodb_log_file_size = 64M

innodb_log_buffer_size = 8M

innodb_flush_log_at_trx_commit = 1

innodb_lock_wait_timeout = 50

进入mysql目录

cd /usr/local/eetrust/mysql/bin

添加用户mysql

./mysql_install_db --user=mysql

--设置用户密码

./mysqld_safe --user=mysql &

./mysqladmin -u root password sunnyboysac

--设置mysql自启动

--进入解压目录

--拷贝文件

cd /usr/sid/mysql/mysql-5.0.85

cp support-files/mysql.server /etc/rc.d/init.d/mysql

--修改权限

cd /etc/rc.d/init.d

chmod +x /etc/rc.d/init.d/mysql

--设置自启动

chkconfig --add mysql

chkconfig mysql on

--将mysql的bin添加到/etc/profile的path中

vi /etc/profile

--在path后面加入如下内容

:/usr/local/eetrust/mysql/bin

--应用

source /etc/profile

mysql -uroot –psunnyboysac

--给mysql的用root用户授权，使其远程可以访问

grant all on *.* to 'root'@'%' identified by 'mysqladmin';

grant all on *.* to 'root'@'%' identified by 'sunnyboysac';

GRANT USAGE ON *.* to root@'%' IDENTIFIED BY 'sunnyboysac';

--刷新

flush privileges;

如果还连不上，关掉防火墙

service iptables stop

验证：

service mysql start

退出窗口重新登录

用mysql命令
