CentOS6.3源码安装mysql5.6.15-Alex

spell

　　mysql从5.5版本开始，不再使用./configure编译，而是使用cmake编译器http://dev.mysql.com/doc/refman/5.6/en/source-configuration-options.html
　　mysql-5.6.16.tar.gz源码包下载地址：
　　wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz
　　我的mysql目录配置如下：
　　安装路径：/usr/local/mysql
　　数据库路径：/data/mysql
　　源码包存放位置：/usr/software
　　准备工作：安装基本依赖包，先安装cmake、automake 、autoconf ，
　　另MySQL 5.6.x需要最少安装的包有：bison,gcc、gcc-c++、ncurses-devel
　　[root@localhost ~]# yum install cmake make -y
　　[root@localhost ~]# yum install gcc gcc-c++ autoconf bison automake zlib fiex libxml ncurses-devel libmcrypt libtool-ltdl-devel* -y
　　[root@localhost ~]# cp /root/mysql-5.6.15.tar.gz /usr/software/
　　[root@localhost ~]# cd /usr/software
　　开始编译安装
　　[root@localhost ~]# tar -zxvf mysql-5.6.15.tar.gz
　　[root@localhost ~]# cd mysql-5.6.15
　　[root@localhost ~]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
　　-DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock \
　　-DDEFAULT_CHARSET=utf8 \
　　-DDEFAULT_COLLATION=utf8_general_ci \
　　-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \
　　-DWITH_INNOBASE_STORAGE_ENGINE=1 \
　　-DWITH_READLINE=1 \
　　-DENABLED_LOCAL_INFILE=1 \
　　-DMYSQL_DATADIR=/data/mysql/ \
　　-DMYSQL_USER=mysql \
　　-DMYSQL_TCP_PORT=3306
　　[root@localhost ~]# make && make install
　　mysql官网英文文档简单翻译说明一下
　　The MyISAM, MERGE, MEMORY, and CSV engines are mandatory (always compiled into the server) and need not be installed explicitly.（说明：mysql默认支持的数据库引擎有MyISAM, MERGE, MEMORY, CSV，无需在编译时再声明）
　　所以上面的编译条件省掉了如下两行
　　-DWITH_MYISAM_STORAGE_ENGINE=1 \
　　-DWITH_MEMORY_STORAGE_ENGINE=1 \
　　但INNODB一定要声明式安装，所以多了这一行
　　-DWITH_INNOBASE_STORAGE_ENGINE=1 \
　　查看mysql.mysql的用户及组是否存在
　　[root@localhost ~]# cat /etc/passwd |grep mysql
　　mysql:x:501:503::/home/mysql:/bin/bash
　　[root@localhost ~]# cat /etc/group |grep mysql
　　mysql:x:503:
　　不OK就执行以下两行命令（否则跳过这一步）
　　[root@localhost ~]# groupadd mysql                                          #添加mysql用户组
　　[root@localhost ~]# useradd mysql -g mysql -s /sbin/nologin        # 添加mysql用户
　　以下带红色字体的命令非常非常，必须要执行
　　[root@localhost ~]# cd /usr/local/mysql
　　[root@localhost ~]# chown mysql.mysql -R .                              #将mysql目录赋予mysql用户的执行权限
　　[root@localhost ~]# chown mysql.mysql -R /data/mysql
　　[root@localhost ~]# cp support-files/my-default.cnf /etc/my.cnf  #mysql配置文件
　　[root@localhost ~]# chmod 755 scripts/mysql_install_db              #赋予mysql_install_db执行权限
　　以下命令为mysql 启动及自启动配置
　　[root@localhost ~]# scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/mysql --datadir=/data/mysql/
　　输出如下信息：

　　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:
　　/usr/local/mysql/bin/mysqladmin -u root password 'new-password'
　　/usr/local/mysql/bin/mysqladmin -u root -h ziteng26 password 'new-password'
　　Alternatively you can run:
　　/usr/local/mysql/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 . ; /usr/local/mysql/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!
　　The latest information about MySQL is available on the web at
　　http://www.mysql.com
　　Support MySQL by buying support/licenses at http://shop.mysql.com
　　New default config file was created as /usr/local/mysql/my.cnf and
　　will be used by default by the server when you start it.
　　You may edit this file to change server settings
　　WARNING: Default config file /etc/my.cnf exists on the system
　　This file will be read by default by the MySQL server
　　If you do not want to use this, either remove it, or use the
　　--defaults-file argument to mysqld_safe when starting the server
　　[root@localhost ~]# cp support-files/mysql.server /etc/init.d/mysqld
　　[root@localhost ~]# chmod 755 /etc/init.d/mysqld
　　查看mysqld服务是否设置为开机启动
　　[root@localhost ~]# chkconfig --list|grep mysqld
　　设置为开机启动
　　[root@localhost ~]# chkconfig mysqld on
　　启动mysql数据库，会输出一系列有用的信息，告诉你接下去如何初始化mysql
　　[root@CentOS mysql]# service mysqld start
　　按照上述英文，我们来初始化管理员root的密码
　　[root@localhost ~]# /usr/local/mysql/bin/mysqladmin -u root password 'yourpassword'
　　此处yourpassword设置为 manager
　　众所周知，mysql有两种帐号类型，即localhost和%，前者限本机连接mysql，后者可用于其它机器远程连接mysql，最后，处理帐号登录问题，让root帐号密码可以本地和远程连接使用
　　[root@localhost ~]# /usr/local/mysql/bin/mysql -u root -p         #敲入该命令后，屏幕会提示输入密码，输入上一步设置的yourpassword
　　删除root密码为空的记录
　　mysql> use mysql;
　　mysql> delete from user where password='';
　　mysql> flush privileges;
　　配置mysql允许root远程登录                                  #登录

　　mysql> grant all privileges on . to root@'%'>　　mysql> flush privileges;
　　mysql> select User,Password,Host from user;
　　

上述命令如果执行成功　　

　　
mysql> quit
