LinuxMySQL免安装及配置

下载MySQL软件包到指定目录

/home/codebrother/mysql/mysql-5.1.72-linux-x86_64-glibc23.tar

创建MySQL安装主目录

我的机器以mysql_db命名为mysql的主目录&＃xff0c;创建mysql_db目录&＃xff0c;并进入mysql_db目录&＃xff0c;如图一

mkdir mysql_db

cd mysql_db

解压缩MySQL软件包&＃xff0c;如图二

tar -xvf /home/codebrother/mysql/mysql-5.1.72-linux-x86_64-glibc23.tar

修改解压后的目录名称&＃xff0c;如图三

执行命令格式&＃xff1a;mv 源目录名称 新目录名称

mv mysql-5.1.72-linux-x86_64-glibc23 mysql-5.1.72

复制my-medium.cnf文件到指定目录&＃xff0c;并命名为my.cnf&＃xff0c;如图四、图五

进入mysql-5.1.72目录&＃xff0c;执行命令&＃xff1a;

cd mysql-5.1.72/support-files/

cp my-medium.cnf ../my.cnf

再返回mysql_db目录&＃xff0c;看到my.cnf文件已经在此目录下

配置my.cnf文件

编辑my.cnf文件,默认内容如图六

vim my.cnf

检查MySQL默认端口3306是否被占用&＃xff0c;如图七

执行命令&＃xff1a;netstat -apn | grep 3306

3306已经被占用&＃xff0c;那么换一个端口&＃xff0c;建议端口号在10000以上&＃xff0c;比如改成13306&＃xff0c;如图八

在[client]里修改port端口号

port&＃61;13306

在[client]里修改sock文件位置&＃xff1a;

socket &＃61; /home/codebrother/mysql_db/mysql-5.1.72/mysql.sock

在[mysqld]里修改port&＃61;13306

port &＃61; 13306

在[mysqld]里修改sock文件位置&＃xff1a;

socket &＃61; /home/codebrother/mysql_db/mysql-5.1.72/mysql.sock

在[mysqld]里添加MySQL基础目录&＃xff1a;

basedir &＃61; /home/codebrother/mysql_db/mysql-5.1.72

在[mysqld]里添加MySQL数据存储目录&＃xff1a;

datadir &＃61; /home/codebrother/mysql_db/mysql-5.1.72/data

在[mysqld]里添加MySQL日志文件&＃xff1a;

log-error &＃61; /home/codebrother/mysql_db/mysql-5.1.72/logs/mysql_error.log

在[mysqld]里添加MySQL进程文件&＃xff1a;

pid-file &＃61; /home/codebrother/mysql_db/mysql-5.1.72/mysql.pid

在[mysqld]里添加指定MySQL数据库所属用户&＃xff1a;

user &＃61; codebrother  &＃xff08;这里填写你所用的linux用户&＃xff09;

按ESC键&＃xff0c;输入:wq 即保存退出。

创建logs目录

在mysql_db目录下创建logs目录&＃xff0c;如图十

执行命令&＃xff1a;mkdir logs

安装MySQL

执行安装命令&＃xff1a;

./script/mysql_install_db --defaults-file&＃61;my.cnf

如果执行成功&＃xff0c;会提示如下内容&＃xff1a;

[codebrother&＃64;codebrother mysql-5.1.72]$ ./scripts/mysql_install_db --defaults-file&＃61;my.cnf

WARNING: The host &＃39;codebrother&＃39; could not be looked up with resolveip.

This probably means that your libc libraries are not 100 % compatible

with this binary MySQL version. The MySQL daemon, mysqld, should work

normally with the exception that host name resolving will not work.

This means that you should use IP addresses instead of hostnames

when specifying MySQL privileges !

Installing MySQL system tables...

150904 17:27:00 [Warning] &＃39;--skip-locking&＃39; is deprecated and will be removed in a future release. Please use &＃39;--skip-external-locking&＃39; instead.

OK

Filling help tables...

150904 17:27:01 [Warning] &＃39;--skip-locking&＃39; is deprecated and will be removed in a future release. Please use &＃39;--skip-external-locking&＃39; instead.

OK

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/home/codebrother/mysql_db/mysql-5.1.72/bin/mysqladmin -u root password &＃39;new-password&＃39;

/home/codebrother/mysql_db/mysql-5.1.72/bin/mysqladmin -u root -h codebrother password &＃39;new-password&＃39;

Alternatively you can run:

/home/codebrother/mysql_db/mysql-5.1.72/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /home/codebrother/mysql_db/mysql-5.1.72 ; /home/codebrother/mysql_db/mysql-5.1.72/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd /home/codebrother/mysql_db/mysql-5.1.72/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /home/codebrother/mysql_db/mysql-5.1.72/scripts/mysqlbug script!

启动MySQL&＃xff0c;如图十一

执行命令&＃xff1a;

bin/mysqld_safe --defaults-file&＃61;my.cnf &

检查MySQL端口、sock文件、log日志文件

检查端口&＃xff0c;执行命令&＃xff1a;

netstat -an | apn 13306

如图&＃xff0c;代表mysql已经使用13306端口&＃xff0c;正常运行&＃xff0c;如图十二

查看sock文件是否存在&＃xff0c;如图十三&＃xff0c;即为正常状态

查看logs日志文件&＃xff0c;内容如下&＃xff0c;如果有错误&＃xff0c;会提示Error&＃xff0c;请仔细检查一下。

[codebrother&＃64;codebrother mysql-5.1.72]$ cat logs/mysql_error.log

执行命令&＃xff1a;

showdatabases;

drop database test;

查看内置MySQL用户&＃xff0c;删除匿名用户&＃xff0c;如图十六

切换到mysql数据库&＃xff0c;执行命令&＃xff1a;

use mysql;

select host, user, password from user;

执行删除命令&＃xff0c;并确认已经删除匿名用户&＃xff0c;如图十七

delete from user where user &＃61; &＃39;&＃39;;

修改用户密码&＃xff0c;如图十八

use mysql;

update user set password &＃61; password(&＃39;root&＃39;);

至此免安装MySQL配置已经完毕&＃xff01;
