mysql5.6.14 安装笔记

1：下载mysql
http://dev.mysql.com/downloads/mysql/#downloads platfrom ：source code
2:先安装cmake（mysql5.5以后是通过cmake来编译的）
yum安装

yum install cmake

3：

mkdir /usr/local/mysql                  //安装目录
mkdir /mnt/resource/mysqldate        //数据存放目录

4:

groupadd mysql
useradd -r -g mysql mysql

5:

tar -zxvf mysql.5.6.14.tar.gz
cd mysql.5.6.14.tar.gz

6 ：

mkdir build&& cd build
cmake ..
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/mnt/resource/mysqldate
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DEXTRA_CHARSETS=all
-DENABLED_LOCAL_INFILE=1

参数说明-DCMAKE_INSTALL_PREFIX=/usr/local/mysql //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
重新编译时，需要清除旧的对象文件和缓存信息。#make 之后# make clean# rm -f CMakeCache.txt# rm -rf /etc/my.cnf安装过程中会报很多错，大体能在一下网站解决http://blog.chinaunix.net/uid-13954789-id-3432115.html

================================================================================================
安装过程并不顺利，遇到好几次错误1.没有安装 gcc 和 gcc-c++，执行cmake报如下错误：==================================================[root@ice mysql-5.5.27]# cmake .-- The C compiler identification is unknown-- The CXX compiler identification is unknownCMake Error: your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found. Please set CMAKE_C_COMPILER to a valid compiler path or name.CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name..-- Configuring incomplete, errors occurred!==================================================解决方法：安装gcc和gcc-c++yum install gccyum install gcc-c++#删除cache文件，不删除还会报错rm CMakeCache.txt cmake .2.编译快结束时，又报如下错误：Warning: Bison executable not found in PATH解决方法：安装bisonyum install bisonrm CMakeCache.txt cmake .#编译通过make && make install#执行时间比较长
3.无法启动mysqlbin/mysqld_safe --user=mysql & 无法启动解决方法：再执行一次scripts/mysql_install_db --user=mysql为什么会这样，原因不明====================================================================

下载的版本有问题。正确的版本如下：1、http://dev.mysql.com/downloads/mysql/2、选择 MySQL Community Server3、

7：配置(1)设置目录权限

[root@pacteralinux mysql-5.6.14]# cd /usr/local/mysql/
[root@pacteralinux mysql]# chown -R root:mysql . //把当前目录中所有文件的所有者所有者设为root，所属组为mysql
[root@pacteralinux mysql]# cd /mnt/resource/data/
[root@pacteralinux data]# chown -R mysql:mysql  .
[root@pacteralinux data]# cd /usr/local/mysql/
[root@pacteralinux mysql]# cd support-files/
[root@pacteralinux support-files]# cp my-default.cnf /etc/my.cnf   //将mysql的启动服务添加到系统服务中

（2）配置文件

vi /etc/my.cnf
basedir =/usr/local/mysql
datadir =/mnt/resource/mysqldate
port =3306
socket =/mnt/resource/mysqldate/mysql.sock
创建mysql.sock
[root@pacteralinux mysqldate]# touch mysql.sock
[root@pacteralinux mysqldate]# ll
-rw-r--r--. 1 root root 0 Sep 25 03:26 mysql.sock

8：初始化数据库

[root@pacteralinux mysql]# ./scripts/mysql_install_db --user=mysql --no-defaults

9：设置环境变量

[root@pacteralinux mysql]# vi /root/.bash_profile
在PATH=$PATH:$HOME/bin添加参数为：
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib
[root@pacteralinux mysql]# source /root/.bash_profile

10:设定启动脚本

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

11：启动数据库
启动方式一：

[root@pacteralinux mysql]# pwd
/usr/local/mysql
[root@pacteralinux mysql]# ./bin/mysqld_safe --user=mysql &
[1] 36019
[root@pacteralinux mysql]# 130925 04:44:10 mysqld_safe Logging to '/mnt/resource/mysqldate/pacteralinux.err'.
130925 04:44:10 mysqld_safe Starting mysqld daemon with databases from /mnt/resource/mysqldate
130925 04:44:11 mysqld_safe mysqld from pid file /mnt/resource/mysqldate/pacteralinux.pid ended

启动方式二：

[root@pacteralinux mysqldate]# service mysql start
mysql: unrecognized service

3. 启动方式三：

[root@pacteralinux mysqldate]#  /etc/rc.d/init.d/mysqld start
Starting MySQL.The server quit without updating PID file (/mnt/resource/mysqldate/pacteralinux.pid).[FAILED]

可以看到，每种启动方式都是报错
在MYSQL启动老失败即：Starting MySQL.Manager of pid-file quit without updating file.[FAILED]
查看错误日志显示：mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
/usr/local/mysql/bin/mysqld: Table 'mysql.plugin' doesn't exist

Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
InnoDB: The first specified data file ./ibdata1 did not exist:
这是执行scripts/mysql_install_db --user=mysql没有成功的原因，没有一个初始化数据库，不能启动mysql守护进程，重新执行

[root@pacteralinux mysql]# scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/mnt/resource/mysqldate --user=mysql

重新启动:

[root@pacteralinux mysql]# /etc/rc.d/init.d/mysqld start
Starting MySQL[  OK  ]
[root@pacteralinux mysql]# service mysql start
mysql: unrecognized service
#解决
[root@pacteralinux mysql]# chkconfig mysqld on
[root@pacteralinux mysql]# service mysql start
mysql: unrecognized service
[root@pacteralinux mysql]# service mysqld start
Starting MySQL[  OK  ]

12；连接数据库

[root@pacteralinux mysql]# mysql -u root mysql
mysql>
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+

Mysql刚安装完有两个数据库：mysql和test。mysql库非常重要，它里面有MySQL的系统信息，我们改密码和新增用户，实际上就是用这个库中的相关表进行操作。mysql> use mysql
Database changed
mysql> show tables
mysql> describe usermysql> select * from user
13：增加数据用户

格式：grant select on 数据库.* to 用户名@登录主机 identified by "密码"
例1、增加一个用户user_1密码为123，让他可以在任何主机上登录，并对所有数据库有查询、插入、修改、删除的权限。首先用以root用户连入MySQL，然后键入以下命令：

mysql> grant select,insert,update,delete on *.* to user_1@"%" Identified by "123";

例1增加的用户是十分危险的，如果知道了user_1的密码，那么他就可以在网上的任何一台电脑上登录你的MySQL数据库并对你的数据为所欲为了，解决办法见例2。
例2、增加一个用户user_2密码为123,让此用户只可以在localhost上登录，并可以对数据库aaa进行查询、插入、修改、删除的操作（localhost指本地主机，即MySQL数据库所在的那台主机），这样用户即使用知道user_2的密码，他也无法从网上直接访问数据库，只能通过MYSQL主机来操作aaa库。

mysql>grant select,insert,update,delete on aaa.* to user_2@localhost identified by "123";

[b]14：修改MySQL的root用户的密码以及打开远程连接[/b]

[root@ pacteraLinux]# mysql -u root mysql  mysql>use mysql;
mysql>desc user;
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";　　//为root添加远程连接的能力。
mysql>update user set Password = password('xxxxxx') where User='root';
mysql>select Host,User,Password  from user where User='root';
mysql>flush privileges;
mysql>exit
#重新登录
mysql -u root -p
#若还不能进行远程连接，则关闭防火墙
[root@ pacteraLinux~]# /etc/rc.d/init.d/iptables stop

[b]15：错误总结[/b]

15.1出现过如下错误，数据库启动正常，但是连接不上mysql，如下

[root@pacteralinux mysql]# service mysqld restart
Shutting down MySQL...[  OK  ]
Starting MySQL....[  OK  ]
[root@pacteralinux mysql]# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/mnt/resource/mysqldate/mysql.sock' (111)

解决方法1，在数据存放目录下创建/mnt/resource/mysqldate/mysql.sock文件2，在配置配件/etc/my.cnf中添加socket =/mnt/resource/mysqldate/mysql.sock配置文件全文如下：

[root@pacteralinux mysqldate]# vi /etc/my.cnf
[client]
socket =/mnt/resource/mysqldate/mysql.sock
[mysqld]
basedir =/usr/local/mysql
datadir =/mnt/resource/mysqldate
port =3306
socket =/mnt/resource/mysqldate/mysql.sock
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

15.2：在配置文件中添加了几个配置选项时出现过错误，The server quit without updating PID file增加的几条配置为全部从A服务器复制过来的，但是出现了错误，说明尽管数据库一样，对不同的版本差异很大！15.36.4 ;本地登陆可以，但是远程登录报如下错误连接mysql时 出现错误ERROR 2003 (HY000): Can't connect to MySQL server on 'xx.xx.xx.xx' (110)
复制代码此处错误id 110 用perror 查出结果为OS error code 110: Connection timed out
复制代码可以查看一下网络是否正常，使用telnet xx.xx.xx.xx 3306
发现端口不通，ping 一下该主机，也没反应！关闭防火墙之后问题依旧，打电话给云平台的admin，发现外围网络屏蔽了该端口！
