linux 怎么部署mysql数据库

创建用于执行mysql服务程序的帐号：

[root@linuxprobe cmake-28112]# cd

[root@linuxprobe src]# useradd mysql -s /sbin/nologin

创建数据库程序和文件的目录，并设置目录的所属与所组：

[root@linuxprobe src]# mkdir -p /usr/local/mysql/var

[root@linuxprobe src]# chown -Rf mysql:mysql /usr/local/mysql

安装Mysql服务程序（解压与编译过程已省略）：

[root@linuxprobe src]# tar xzvf mysql-5619targz

[root@linuxprobe src]# cd mysql-5619/

[root@linuxprobe mysql-5619]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/var -DSYSCONFDIR=/etc

[root@linuxprobe mysql-5619]# make

[root@linuxprobe mysql-5619]# make install

删除系统默认的配置文件：

[root@linuxprobe mysql-5619]# rm -rf /etc/mycnf

生成系统数据库（生成信息已省略）：

[root@linuxprobe mysql-5619]# cd /usr/local/mysql

[root@linuxprobe mysql]# /scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var

创建配置文件的软连接文件：

[root@linuxprobe mysql]# ln -s mycnf /etc/mycnf

将mysqld服务程序添加到开机启动项：

[root@linuxprobe mysql]# cp /support-files/mysqlserver /etc/rcd/initd/mysqld

[root@linuxprobe mysql]# chmod 755 /etc/initd/mysqld

[root@linuxprobe mysql]# chkconfig mysqld on

编辑启动项的配置文件：

[root@linuxprobe mysql]# vim /etc/rcd/initd/mysqld

//分别修改第46与47行，basedir为程序安装路径，datadir为数据库存放目录。

basedir=/usr/local/mysql

datadir=/usr/local/mysql/var

重启mysqld服务程序：

[root@localhost mysql]# service mysqld start

Starting MySQL SUCCESS!

把mysql服务程序命令目录添加到环境变量中（永久生效）：

[root@linuxprobe mysql]# vim /etc/profile

//在配置文件的最下面追加：

export PATH=$PATH:/usr/local/mysql/bin

[root@linuxprobe mysql]# source /etc/profile

将mysqld服务程序的库文件链接到默认的位置：

[root@linuxprobe mysql]# mkdir /var/lib/mysql

[root@linuxprobe mysql]# ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql

[root@linuxprobe mysql]# ln -s /usr/local/mysql/include/mysql /usr/include/mysql

[root@linuxprobe mysql]# ln -s /tmp/mysqlsock /var/lib/mysql/mysqlsock

初始化mysqld服务程序：

[root@linuxprobe mysql]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current

password for the root user If you've just installed MySQL, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here

Enter current password for root (enter for none):

OK, successfully used password, moving on

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation

Set root password [Y/n] y

New password: 输入要为root用户设置的数据库密码。

Re-enter new password: 重复再输入一次密码。

Password updated successfully!

Reloading privilege tables

Success!

By default, a MySQL installation has an anonymous user, allowing anyone

to log into MySQL without having to have a user account created for

them This is intended only for testing, and to make the installation

go a bit smoother You should remove them before moving into a

production environment

Remove anonymous users [Y/n] y（删除匿名帐号）

Success!

Normally, root should only be allowed to connect from 'localhost' This

ensures that someone cannot guess at the root password from the network

Disallow root login remotely [Y/n] y(禁止root用户从远程登陆)

Success!

By default, MySQL comes with a database named 'test' that anyone can

access This is also intended only for testing, and should be removed

before moving into a production environment

Remove test database and access to it [Y/n] y(删除test数据库并取消对其的访问权限)

- Dropping test database

Success!

- Removing privileges on test database

Success!

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately

Reload privilege tables now [Y/n] y(刷新授权表，让初始化后的设定立即生效)

Success!

All done! If you've completed all of the above steps, your MySQL

installation should now be secure

Thanks for using MySQL!

Cleaning up

可以百度搜索Linux就该这么学，第9章 使用Apache服务部署静态网站，里面有部署mysql的资料

1、 将mysql-connector-java-516-binjar,也在%Tomcat_Home%\common\lib\下,

2、 在tomcat中manager中配置数据源名,配置完后内容自动放在conf\serverxml中。

3、 在conf\catalina\localhost\下建你应用程序的xml文件，例wei2xml中,内容为<Context docBase="wei2" path="/wei2">

<ResourceLink global="jdbc/mysql" name="jdbc/mysql" type="javaxsqlDataSource"/>

</Context>

其中jdbc/mysql为配置的JNDI;

下面说下JNDI与DataSource

JNDI java naming directory interface命名和目录接口命名服务来使组件定位到其它组件和资源（数据库资源）,JNDI所有名应该以字符串java:comp/env开始；

要定位JDBC资源中，这时就可以编写代码使用JNDI的lookup()方法来定位到这个资源了。

JNDI命名服务有一组将名称与对象联系在一起的绑定。JNDI中的lookup()方法传递一个JNDI参数（java:comp/env/myjdbc,前面java:comp/env是必要的。），返回相应的对象(返回类型为DataSource,若为数据库，则可用DataSource中的getConnection()方法获取数据库连接)
