可能因为有各种情况，无法通过yum安装mysql，这里记录一下编译安装的简单步骤
使用yum安装一些依赖
yum -y install make gcc-c++ cmake bison-devel ncurses-devel
yum install -y gcc gcc-c++ kernel-devel
yum install -y readline-devel pcre-devel openssl-devel openssl zlib zlib-devel pcre-devel
下载编译安装mysql
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.22.tar.gz
tar -zxvf mysql-5.6.22.tar.gz
cd mysql-5.6.22
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci
make && make install
创建mysql用户
groupadd mysql
useradd -g mysql mysql
创建目录并分配权限
mkdir /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
进入安装目录执行脚本，启动服务
cd /usr/local/mysql
scripts/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –user=mysql
cp support-files/mysql.server /etc/init.d/mysql
rm -rf /etc/my.cnf
chkconfig mysql on
service mysql start
设置之前，我们需要先设置PATH，要不不能直接调用mysql
ln -s /usr/local/mysql/bin/mysql /usr/bin/
现在，我们可以在终端内直接输入mysql进入，mysql的环境了
mysql
然后开始给数据库管理员设置密码和访问权限
grant all on . to root@”%” identified by “密码写这里”;
FLUSH PRIVILEGES;
exit;
这样就可以通过远程访问mysql了，记得把iptables打开
