数据库学习之--RedHat EL55下Mysql源码包安装

系统环境

操作系统:RedHat EL55

DB Soft: Mysql 5.6.4-m7

Mysql 在linux下的安装方式有两种版本,一种为Binary(二进制),另外一种为Source(源码包),本文为Source Install方式。

1、安装前的准备

解压安装包

[oracle@ogg ~]$ ls

查看官方安装文档:INSTALL-SOURCE

To install and use a MySQL binary distribution, the basic command

sequence looks like this:

[cpp] view
plaincopyprint?

shell> groupadd mysql

shell> useradd -r -g mysql mysql

shell> cd /usr/local

shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz

shell> ln -s full-path-to-mysql-VERSION-OS mysql

shell> cd mysql

shell> chown -R mysql .

shell> chgrp -R mysql .

shell> scripts/mysql_install_db --user=mysql

shell> chown -R root .

shell> chown -R mysql data

# Next command is optional

shell> cp support-files/my-medium.cnf /etc/my.cnf

shell> bin/mysqld_safe --user=mysql &

# Next command is optional

shell> cp support-files/mysql.server /etc/init.d/mysql.server

For example, with a compressed tar file source distribution on Unix, the basic installation command

sequence looks like this:

[cpp] view
plaincopyprint?

# Preconfiguration setup

shell> groupadd mysql

shell> useradd -r -g mysql mysql

# Beginning of source-build specific instructions

shell> tar zxvf mysql-VERSION.tar.gz

shell> cd mysql-VERSION

shell> cmake .

shell> make

shell> make install

# End of source-build specific instructions

# Postinstallation setup

shell> cd /usr/local/mysql

shell> chown -R mysql .

shell> chgrp -R mysql .

shell> scripts/mysql_install_db --user=mysql

shell> chown -R root .

shell> chown -R mysql data

# Next command is optional

shell> cp support-files/my-medium.cnf /etc/my.cnf

shell> bin/mysqld_safe --user=mysql &

# Next command is optional

shell> cp support-files/mysql.server /etc/init.d/mysql.server

2、准备源码安装所需要的工具和库文件(RedHat 安装光盘)

[cpp] view
plaincopyprint?

[root@ogg ~]# rpm -qa |grep make

automake-1.11.1-1.2.el6.noarch

make-3.81-19.el6.i686

[root@ogg ~]# rpm -qa |grep bison

bison-2.4.1-5.el6.i686

[root@ogg ~]# rpm -qa |grep gcc

gcc-c++-4.4.4-13.el6.i686

libgcc-4.4.4-13.el6.i686

gcc-4.4.4-13.el6.i686

gcc-gfortran-4.4.4-13.el6.i686

compat-libgcc-296-2.96-144.el6.i686

[root@ogg ~]# rpm -qa |grep cmake

[root@ogg ~]# rpm -qa |grep ncur

ncurses-base-5.7-3.20090208.el6.i686

ncurses-libs-5.7-3.20090208.el6.i686

ncurses-5.7-3.20090208.el6.i686

ncurses-devel-5.7-3.20090208.el6.i686

挂载RedHat安装光盘

[root@ogg ~]# mount /dev/cdrom /media/

mount: block device /dev/sr0 is write-protected, mounting read-only

[root@ogg ~]# cd /media/

[root@ogg media]# cd Server/

[root@ogg Server]# ls

Packages repodata TRANS.TBL

[root@ogg Server]# cd Packages/

[root@ogg Packages]# ls |grep make

automake-1.11.1-1.2.el6.noarch.rpm

imake-1.0.2-11.el6.i686.rpm

make-3.81-19.el6.i686.rpm

makebootfat-1.4-10.el6.i686.rpm

pacemaker-1.1.2-7.el6.i686.rpm

pacemaker-libs-1.1.2-7.el6.i686.rpm

对于RedHat EL55系统,安装光盘不包含cmake文件,需要从网上下载安装

数据库启动失败
140917 13:58:18 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist


解决方法:

修改/etc/my.cnf

[mysqld]

datadir=/var/lib/mysql

重新指定数据库数据文件的位置!

再次启动Database:

[root@rh55 mysql]# bin/mysqld_safe --user=mysql &

[java] view
plaincopyprint?

[root@ogg data]# ps -ef |grep mysql

root 16955 5955 0 14:03 pts/1 00:00:00 /bin/sh ./mysqld_safe --user=mysql

mysql 17229 16955 0 14:03 pts/1 00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/var/lib/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/var/lib/mysql/ogg.err --pid-file=/var/lib/mysql/ogg.pid --socket=/tmp/mysql.sock --port=3306

[root@ogg data]# netstat -an|grep 3306

tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN

数据库启动成功!

配置数据库启动脚本,加入系统启动环境

[java] view
plaincopyprint?

[root@ogg mysql]# cp support-files/mysql.server /etc/init.d/mysql

[root@ogg mysql]# service mysql stop

Shutting down MySQL..140917 14:06:29 mysqld_safe mysqld from pid file /var/lib/mysql/ogg.pid ended

[ OK ]

[1]+ Done ./mysqld_safe --user=mysql (wd: /usr/local/mysql/bin)

(wd now: /usr/local/mysql)

[root@ogg data]# netstat -an|grep 3306

[root@ogg mysql]# service mysql start

Starting MySQL..

[root@ogg data]# netstat -an|grep 3306

tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN [ OK ]

8、连接使用mysql database
修改管理员密码
[root@rh55 mysql]# cd /usr/local/mysql/
[root@rh55 mysql]# ./bin/mysqladmin -u root password
New password:
Confirm new password:

连接数据库
[root@rh55 mysql]# ./bin/mysql -u root -p
