mysql在centos上的编译安装

环境：centos6.5  mysql-5.6.17.tar.gz

wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.17.tar.gz

yum install -y gcc gcc-c++ gcc-c++.x86_64 bison.x86_64 libaio.x86_64 cmake.x86_64 ncurses-devel.x86_64

后面根据官方文档： MySQL 5.6 Manual 2.8.2 Installing MySQL Using a Standard Source Distribution

shell> groupadd mysql
shell> useradd -r -g mysql mysql

shell> tar zxvf mysql-VERSION.tar.gz
shell> cd mysql-VERSION
shell> cmake .
shell> make
shell> make install
shell> cd /usr/local/mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &
安装完了 ，启动的时候就报错：
/usr/local/mysql/bin/mysqld: Can‘t create/write to file ‘/var/run/mysqld/mysqld.pid‘ (Errcode: 2 - No such file or directory)
cd /var/run/
mkdir mysqld
chown -R mysql mysqld
chgrp -R mysql mysqld
再重新启动：
[ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.user‘ doesn‘t exist
修改：/usr/local/mysql/my.cnf
datadir =/usr/local/mysql/data
重启电脑 
mysql.server start 启动成功
./bin/mysql
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘ (2)
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
执行这个命令后，成功运行mysql
