Linux下MySQL5.6源码安装

1、首先安装依赖包，避免在安装过程中出现问题

shell>yum install cmake                --（mysql5.5以后是通过cmake来编译的）shell>yum install ncurses-devel      --Redhat执行cmake是需要依赖的包，如缺少编译报错shell>yum install bison-develshell>yum install libaio-develshell>yum install gcc-c++

2、创建mysql用户及用户组

shell> groupadd mysqlshell> useradd -r -g mysql mysql     // -r option means mysql is only a system account and can't login as a regular usershell> id mysqluid=497(mysql) gid=502(mysql) 组=502(mysql)

3、创建mysql的安装目录及数据库存放目录

shell> mkdir -p /db/mysql                 #安装mysql shell> mkdir -p /db/mysql/data            #存放数据库

4、安装mysql

shell>  unzip mysql-5.6.19.zipshell>  cd mysql-5.6.19shell>  cmake . -DCMAKE_INSTALL_PREFIX=/db/mysql                -DMYSQL_DATADIR=/db/mysql/data                -DDEFAULT_CHARSET=utf8                 -DDEFAULT_COLLATION=utf8_general_cishell> make && make install

CMAKE参数说明：

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql //默认安装目录
-DINSTALL_DATADIR=/usr/local/mysql/data //数据库存放目录
-DDEFAULT_CHARSET=utf8 　　　 //使用utf8字符
-DDEFAULT_COLLATION=utf8_general_ci //校验字符
-DEXTRA_CHARSETS=all 　　//安装所有扩展字符集
-DENABLED_LOCAL_INFILE=1 　　//允许从本地导入数据
-DMYSQL_USER=mysql
-DMYSQL_TCP_PORT=3306

CMAKE详细介绍参见

注意事项：
如安装失败重新编译时，需要清除旧的对象文件和缓存信息。
shell> make clean
shell> rm -f CMakeCache.txt
shell> rm -rf /etc/my.cnf

5、设置目录权限并创建系统数据库的表

shell> chown -R mysql.mysql /db/mysqlshell> cp /db/mysql/support-files/my-default.cnf /etc/my.cnf                           shell> cp /db/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql        //将mysql的启动服务添加到系统服务中shell> /db/mysql/scripts/mysql_install_db --basedir=/db/mysql/ --datadir=/db/mysql/data/ --user=mysql

6、设置环境变量

shell> vi /root/.bash_profilePATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/libshell> source /root/.bash_profile

7、开启mysql服务

shell>  service mysql startStarting MySQL.......                                      [确定]shell>  chkconfig --add mysql                                      //加入开机启动服务

8、修改MySQL的root用户的密码以及打开远程连接

shell> mysql -u root mysqlmysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "passwd";Query OK, 0 rows affected (0.09 sec)mysql> update user set password=password('passwd') where user='root';mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> exitshell>mysql -u root -pEnter password:

不能通过嵌套文件方式连接

[1]shell> mysql -u root mysqlERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)shell> ls /tmp/mysql.sock ls: 无法访问/tmp/mysql.sock: 没有那个文件或目录shell> ln -s /db/mysql/data/mysql.sock /tmp/mysql.sockshell> ls /tmp/mysql.sock/tmp/mysql.sock[2]修改配置文件/etc/my.cnf并重启mysql服务器指定socket=/tmp/mysql.sock [3]通过TCP/IP连接shell> mysql -h 127.0.0.1 -u root mysqlshell> mysql -u root mysql
