mysql5.6.28源码安装

众所周知,mysql5.5版本之前都是通过./configure进行编译环境检查，mysql5.5之后用的是cmake(包括5.5)

安装前的准备工作：
[root@localhost ~]#wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
[root@localhost ~]#rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
2、安装开发工具包和ncurses-devel
[root@localhost ~]#yum -y groupinstall "Development Tools"
[root@localhost ~]#yum -y install ncurse ncurses-devel
第一部分 编译安装

一、安装环境

1、mysql源码包

http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.28.tar.gz

2、cmake

cmake的重要特性之一是其独立于源码(out-of-source)的编译功能，即编译工作可以在另一个指定的目录中而非源码目录中进行，这可以保证源码目录不受任何一次编译的影响，因此在同一个源码树上可以进行多次不同的编译，如针对于不同平台编译。

(1)源码安装方式

https://cmake.org/download/
[root@localhost ~]# wget https://cmake.org/files/v2.8/cmake-2.8.8.tar.gz
[root@localhost ~]# tar xf cmake-2.8.8.tar.gz
[root@localhost ~]# cd cmake-2.8.8
[root@localhost ~]# ./bootstrap
[root@localhost ~]# make
[root@localhost ~]# make install
(2) yum安装方式

[root@localhost ~] #yum install cmake
二、mysql5.6.28源码安装方法
[root@localhost ~]# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.28.tar.gz
[root@localhost ~]# tar -zxvf mysql-5.6.28.tar.gz
[root@localhost ~]# cd mysql-5.6.28
[root@localhost mysql-5.6.28] #cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/usr/local/mysql/data -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DENABLE_DOWNLOADS=1 -DENABLED_LOCAL_INFILE=1 -DEXTRA_CHARSETS=all

环境检查过程中，若出现以下错误信息：

Curses library not found. Please install appropriate package,

remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

解决方法为：
[root@localhost ~]# rm -f ./CMakeCache.txt
[root@localhost ~]# yum -y install ncurses-devel
[root@localhost ~]# echo $? 查看检查环境过程是否成功，0为成功，其它为失败
3、make编译
[root@localhost ~]# make
4、make install安装

[root@localhost ~]# make install
第二部分 配置mysql为系统服务

三、创建mysql用户和组

[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql
[root@localhost ~]# chown -R mysql:mysql /usr/local/mysql
四、初始化mysql数据库

[root@localhost ~]# cd /usr/local/mysql/scripts
[root@localhost scripts]# ls
mysql_install_db
[root@localhost scripts]# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
注：只要出现了两个OK代表数据库初始化成功

五、复制my.cnf与mysql.server启动文件

[root@localhost scripts]#cd ..
[root@localhost mysql]# cd support-files/
[root@localhost support-files]# cp my-default.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
[root@localhost support-files]# cp mysql.server /etc/init.d/mysqld
[root@localhost support-files]# chmod +x /etc/init.d/mysqld
六、开启mysqld服务

[root@localhost support-files]# service mysqld status
MySQL is not running [失败]
[root@localhost support-files]# service mysqld start
Starting MySQL......... [确定]
[root@localhost ~]# chkconfig mysqld on
七、查看mysqld服务端口号

[root@localhost support-files]# netstat -tunlp | grep mysql
tcp 0 0 :::3306 :::* LISTEN 47557/mysqld
八、初始化数据库密码

[root@localhost support-files]# cd ..
[root@localhost mysql]# cd bin
[root@localhost bin]# ./mysqladmin -u root password 'mysql'
Warning: Using a password on the command line interface can be insecure.
[root@localhost bin]# ./mysql -uroot -p
Enter password:

九、修改全局环境变量

[root@localhost ~]# vim /etc/profile
56 export PATH=$PATH:/usr/local/mysql/bin
[root@localhost ~]#source /etc/profile
[root@localhost ~]# mysql -uroot -p
Enter password:

十、客户端免密码登录设置

[root@localhost ~]# vim .my.cnf
[client]
user = root
password = sa123456
host = localhost
[root@localhost ~]#
