[root@bogon mysql-5.5.60]# service mysqld start
starting mysql.logging to '/usr/local/mysql-5.5.60/data/bogon.err'.
201106 12:50:02 mysqld_safe directory '/var/lib/mysql' for unix socket file don't exists.
error! the server quit without updating pid file (/usr/local/mysql-5.5.60/data/bogon.pid).
解决方法
随即执行命令：cat /usr/local/mysql/data/iz2ze8hspx8qsmxx7b1i9sz.err查看错误原因
error内容如下：
[error] can't start server : bind on unix socket: permission denied
[error] do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ?
结合先前写入配置/etc/my.cnf：
[root@bogon lib]# mkdir mysql
[root@bogon lib]# chmod 777 -r mysql/
最终：
[root@bogon lib]# service mysql start
starting mysql... success!
4 配置环境变量
配置path
# vi ~/.bash_profile
在文件最后面加入以下内容,并使用:wq保存
export path=$path:/usr/local/mysql-5.5.60/bin
刷新path
# source ~/.bash_profile
四、登录并配置远程登录
1 首次登录mysql
[root@bogon lib]# mysql -uroot -p
2 *报错及解决方法
[root@bogon lib]# mysql -uroot -p
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: no such file or directory
系统是redhad8，binary方式安装完mysql之后，mysql命令登录不成功，报错：mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: no such file or directory。按照百度的方法都不成功，应该和系统版本有关，后来自己想到一个方法：yum install libncurses*，完美解决问题。
解决:
[root@bogon lib]# yum -y install libncurses*
[root@bogon lib]# mysql -uroot -p
enter password: #直接回车登录
