Mysql数据库理论基础一:MySQL编译安装
Mysql数据库理论基础一：编译安装一、简介
由MySQL AB公司开发，是最流行的开放源码SQL数据库管理系统，主要特点：
[*] 1、是一种数据库管理系统
[*] 2、是一种关联数据库管理系统
[*] 3、是一种开放源码软件，且有大量可用的共享MySQL软件
[*] 4、MySQL数据库服务器具有快速、可靠和易于使用的特点
[*] 5、MySQL服务器工作在客户端/服务器模式下，或嵌入式系统中
[*]
[*] InnoDB存储引擎将InnoDB表保存在一个表空间内，该表空间可由数个文件创建。这样，表的大小就能超过单独文件的最大容量。表空间可包括原始磁盘分区，从而使得很大的表成为可能。表空间的最大容量为64TB。
[*]
二、安装MySQL ( 依赖gccgcc-c++ncurses-developenssl )
2.1、编译安装前准备
确认系统环境
# uname -a
Linux lamp 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
# ll

-rw-r--r--.1 root root24739429 Mar6 09:04 mysql-5.5.28.tar.gz
# rpm -qa gcc gcc-c++ openssl ncurses-devel
gcc-4.4.4-13.el6.x86_64
gcc-c++-4.4.4-13.el6.x86_64
ncurses-devel-5.7-3.20090208.el6.x86_64
openssl-1.0.0-4.el6.x86_64
安装前需确认开发环境组是否安装：Development Tools（开发工具）和Development Libraries（开发库）
# yum groupinstall "Development Tools"
# yum groupinstall "Development Libraries"
** mysql数据库随着时间的增长，数据会越来越大，所以应该把数据库数据放置在一个单独的可扩展的分区卷上，以便后期管理和备份，挂载在逻辑卷,方法如下：
# fdisk /dev/sda#新建分区
aCommand (m for help): n
p
Partition number (1-4): 1
Last cylinder, +cylinders or +size{K,M,G} (1-2610, default 2610): +10G

2.2、编译安装cmake-2.8.8.tar.gz:
# tar vxf cmake-2.8.8.tar.gz
# cd cmake-2.8.8
# ./configure
# make && make install
...........
-- Installing: /usr/local/doc/cmake-2.8/ccmake.docbook
-- Installing: /usr/local/share/aclocal/cmake.m4 #编译安装cmake完成
2.3、使用cmake编译安装mysql5.5.28:
清理此前的编译所生成的文件，则需使用如下命令：make clean
# tar vxf mysql-5.5.28.tar.gz
# cd mysql-5.5.28
# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/mydata/data -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1-DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_LIBWRAP=0 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock-DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
# -DCMKE_INSTALL_PREFIX=安装路径，-DMYSQL_DATADIR=数据存放路径，-DSYSCONFDIR=配置文件路径，
-DWITH_INNOBASE_STORAGE_ENGINE=1 (是否包含INNOBASE引擎1表示包含0表示不包含)，
-DWITH_ARCHIVE_STORAGE_ENGINE=1 (是否包含ARCHIVE引擎1表示包含0表示不包含)，
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 (是否包含BLACKHOLE空洞引擎1表示包含0表示不包含)，

2.4、配置mysql脚本让其开机自动启动及运行：
# chown -R :mysql /usr/local/mysql#更改组为mysql
# cd /usr/local/mysql
# scripts/mysql_install_db --user=mysql --datadir=/mydata/data#初始化mysql,指定用户和数据目录
Installing MySQL system tables...
OK
Filling help tables...
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:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h lamp password 'new-password'
Alternatively you can run:
./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 . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script! #初始化完成
# mv /etc/my.cnf /etc/my.cnf.back #把原系统中配置文档改名
# cp support-files/my-large.cnf /etc/my.cnf#复制配置文档至/etc目录
# cp support-files/mysql.server /etc/init.d/mysqld#复制启动脚本至/etc/init.d目录中
# chkconfig --add mysqld#把mysqld启动脚本加到开机启动列表
# chkconfig --list mysqld#查看mysqld脚本是否开机启动
mysqld 0:off1:off2:on3:on4:on5:on6:off
# service mysqld start #启动mysql脚本
Starting MySQL...
# vim /etc/profile.d/mysql.sh#编辑环境变量使得mysql命令在PATH变量中
export PATH=$PATH:/usr/local/mysql/bin #新增该行内容
# . /etc/profile.d/mysql.sh #读取mysql.sh脚本的内容
# echo $PATH#输出PATH变量内容
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin#PATH变量中的路径已生效
三、MySQL 启动及簡單应用：
# mysql #启动mysql客户端程序

# mysql -uroot -p#从本机登录mysql,输入刚设定的密码
Enter password:123456
mysql> #正常登录mysql
3.2. 如何设定本机本地登录mysql不用输入密码：
在家目录下，新建一个.my.cnf文档，里面添加以下内容：
# vim .my.cnf
user=root
host=localhost
password=123456
#即使root用户设定了密码，也可以免密码直接读取家目录下面的.my.cnf的隐藏文件进行登录认证。
3.3. 为innodb引擎设置了每表都单独为一个空间
# cd /mydata/data/mysql

附1：
编译mysql出现CMake Error atcmake/readlineNaNake:83
-- Could NOT find Curses(missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readlineNaNake:83 (MESSAGE):
Curses library not found.Please installappropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu,package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readlineNaNake:127 (FIND_CURSES)
cmake/readlineNaNake:217(MYSQL_USE_BUNDLED_LIBEDIT)
CMakeLists.txt:257 (MYSQL_CHECK_READLINE)
-- Configuring incomplete, errors occurred!
该报错原因是未安装ncurses-devel，运行下面命令
第一步：安装
#yum -y install ncurses-devel
第二步：删除CMakeCache.txt
这里是因为，我们在多次运行cmake有个文件我们需要删除，删除当前目录下CMakeCache.txt文件并重新编译，再次运行cmake命令就会正常！
# rm-rf CMakeCache.txt
或者通过find命令找到所有CMakeCache.txt文档的位置
#find / -name CMakeCache.txt
然后全部删除：
# rm -rf/usr/local/src/cmake-2.8.6/Tests/Complex/Cache/CMakeCache.txt
# rm -rf/usr/local/src/cmake-2.8.6/Tests/ComplexOneConfig/Cache/CMakeCache.txt
# rm -rf /usr/local/src/cmake-2.8.6/Tests/ComplexRelativePaths/Cache/CMakeCache.txt
# rm -rf /usr/local/src/mysql-5.5.18/CMakeCache.txt
全部删除后再重新cmake就OK了。
