  export PATH=/usr/local/mysql/bin:$PATH
  
  # source /etc/profile
  

mysql配置

• 配置my.cnf

  # vim /etc/my.cnf
  [mysqld_safe]
  log-error=/data/mysql/log/mysql.err
  
  [mysqld]
  datadir=/data/mysql/data
  tmpdir=/data/mysql/tmp
  socket=/var/lib/mysql/mysql.sock

  default-storage-engine=INNODB
  innodb_buffer_pool_size=1G
  
  slow_query_log=1
  slow_query_log_file=/data/mysql/log/mysql.slow
  long_query_time=2
  
  server_id=1
  log-bin=/data/mysql/log-bin/log-bin
  binlog_format=row
  
  [client]
  socket=/var/lib/mysql/mysql.sock
  

• 创建所需目录

  # mkdir -p /data/mysql/data
  # mkdir -p /data/mysql/log
  # mkdir -p /data/mysql/log-bin
  # mkdir -p /data/mysql/tmp
  
  # mkdir /var/lib/mysql
  

• 创建所需文件

  # touch /data/mysql/log/mysql.err
  

• 改变属主和属组

  # chown -R mysql:mysql /data/mysql
  # chown -R mysql:mysql /var/lib/mysql
  # chown -R mysql:mysql /usr/local/mysql
  

• 执行初始化配置脚本

  # cd /usr/local/mysql
  # bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
  

mysql启动

• 启动

  # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
  # chkconfig --add mysqld
  # chkconfig mysqld on
  # service mysqld restart
