查看当前系统是否安装mysql

[root@localhost mysql]#  rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64

[root@localhost mysql]# rpm -e mysql-libs-5.1.71-1.el6.x86_64
error: Failed dependencies:
libmysqlclient.so.16()(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
libmysqlclient.so.16(libmysqlclient_16)(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
mysql-libs is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64

存在依赖关系，直接删除
[root@localhost mysql]# rpm -e --nodeps  mysql-libs-5.1.71-1.el6.x86_64

[root@localhost mysql]# rpm -qa |grep mysql
没有mysql 即可

安装mysql 所需要的一些必要的库

yum install gcc gcc-c++ ncurses-devel perl

安装cmake

wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz 
或者到 http://note.youdao.com/yws/public/redirect/share?id=ad618b9375cbe1a115edaba83af58390&type=false 下载

可能会出现以下错误：

Connecting to cmake.org|66.194.253.19|:443... connected.
ERROR: certificate common name “*.kitware.com” doesn’t match requested host name “cmake.org”.
To connect to cmake.org insecurely, use ‘--no-check-certificate’.

只需要：

wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz --no-check-certificate

tar -xzvf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./bootstrap ; make ; make install

查看是否成功
cmake--version

用户用户组及目录的创建

groupadd mysql

useradd -r -g mysql mysql

解压 mysql 源码包

tar -zxv -f mysql-5.6.16.tar.gz
cd mysql-5.6.16

cmake 安装

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/soft/mysql-5.6.29/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=/data/mysqldb \
-DMYSQL_TCP_PORT=3306 \
-DENABLE_DOWNLOADS=1

在cmake的时候出现

[root@localhost mysql-5.6.29]# cmake \
> -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
> -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
> -DDEFAULT_CHARSET=utf8 \
CMake Error: The source directory "/usr/local/soft/mysql-5.6.29/ " does not exist.

原因：
在 "\" 后面有空格

cmake 出现以下输出说明cmake成功

编译源码

make && make install

复制配置文件

[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# chmod 755 /etc/init.d/mysqld

初始化数据库

scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysqldb/

出现以下信息说明已经初始化成功
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

启动mysql

/etc/init.d/mysqld start

遇到以下问题：
[root@localhost mysql]# /etc/init.d/mysqld start
Starting MySQL... ERROR! The server quit without updating PID file (/data/mysqldb/localhost.localdomain.pid).

1、可能是/usr/local/mysql/data/mysql.pid文件没有写的权限
解决方法 ：给予权限，执行 “chown -R mysql:mysql /var/data”
“chmod -R 755 /usr/local/mysql/data”  然后重新启动mysqld！

2、可能进程里已经存在mysql进程
解决方法：用命令“ps -ef|grep mysqld”查看是否有mysqld进程
，如果有使用“kill -9  进程号”杀死，然后重新启动mysqld！

3、更多原因请查看：http://www.jb51.net/article/48625.htm

启动完成之后用ps -ef |grep mysql 命令查看是否启动

修改root密码

root 的初始密码为空，登入修改root账户的密码

[root@localhost mysql]# /usr/local/mysql/bin/mysql -u root -p

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> update user set password=PASSWORD("123456") where user='root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4  Changed: 4  Warnings: 0
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

退出

[root@localhost bin]# /usr/local/mysql/bin/mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 7
Server version: 5.6.29 Source distribution

登入成功可以操作数据库了
