150619 15:57:19 [Note] Server socket created on IP: ‘0.0.0.0‘.

150619 15:57:19 [ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.host‘ doesn‘t exist

原因:

./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf 

该步骤（初始化数据库）中my.cnf用的是默认的

而启动时用的是最新的

解决方法：

用最新的配置文件进行初始化

cd /usr/local/mysql/

./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf 

启动没有问题
