准备Mysql的源码,版本号为mysql-5.1.54.tar.gz,linux版本redhat 5.5

安装步骤:

1.解压mysql-5.1.54.tar.gz.

命令: tar -zxvf mysql-5.1.54.tar.gz

2.配置 mysql

进入解压目录，执行下面命令：

./configure --prefix=/usr/local/mysql/ --without-debug --without-bench --enable-thread-safe-client --enable-assembler --enable-profiling --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --with-charset=latin1 --with-extra-charset=ytf8,gbk --with-innodb --with-csv-storage-engine --with-federated-storage --with-mysqld-user=mysql --without-embedded-server --with-server-suffix=-community --with-unix-socket-path=/usr/local/mysql/sock/mysql.sock

3.编译,安装
命令:

make

make install

4.创建用户和组.

groupadd mysql

useradd -g mysql mysql

5.进入mysql目录.创建var目录.并把./share/mysql/my-medium.cnf 拷到mysql目录下并改名为my.cnf.

>mkdir var

>mv share/mysql/my-medium.cnf my.cnf

6.配置my.cnf

配置主要把安装的目录的那几项打开就行.

改动如下:

[client]
#password = your_password
port = 3306
socket = /tmp/mysql3306.sock

# The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql3306.sock

打开下面几项

innodb_data_home_dir = /usr/local/mysql/var/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/var/

innodb_log_arch_dir = /usr/local/mysql/var/

7.安装数据库

命令:./bin/mysql_install_db --defaults-file= /usr/local/mysql /my.cnf --user=mysql

说明:必须用参数--defaults-file指定my.cnf,否则系统用默认的/etc/my.cnf.

8.安装完后,可以看到mysql/var目录下有数据文件,然后用下面命令设置权限:

shell> chown -R root .
shell> chown -R mysql var
shell> chgrp -R mysql .

9.启动数据库.

./bin/mysqld_safe --defaults-file= /usr/local/mysql/my
.cnf --user=mysql &

10.进入数据库.

./bin/mysql -u root --defaults-file= /usr/local/mysql/my.cnf

默认时没有密码,当然如果你删除/etc/my.cnf,可以不要后面的--defaults-file= /usr/local/mysql/my.cnf

11.设为服务并自启动.

对于设置为服务只要把mysql/share/mysql/mysql.server放到/etc/init.d/下改名为mysql

命令:

mv share/mysql/mysql.server /etc/init.d/mysql

chmod 775 /etc/init.d/mysql

chkconfig --add mysql

总结,这只是安装了一个3306端口的mysql,如果要在装一个msyql,步骤一样,只要改动my.cnf文件的内容.

[client]
#password = your_password
port = 3307
socket=/usr/local/mysql/sock/mysql.sock

# The MySQL server
[mysqld]
port = 3307
socket=/usr/local/mysql/sock/mysql.sock
