[root@135 bin]# /etc/init.d/mysqld start
Starting MySQL.170320 22:21:51 mysqld_safe The file /usr/local/mysql/bin/mysqld
does not exist or is not executable. Please cd to the mysql installation
directory and restart this script from there as follows:
./bin/mysqld_safe&
See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information
ERROR! The server quit without updating PID file (/application/mysql/data/135.pid).
解決辦法和思路：
首先是按照錯(cuò)誤的提示操作，嚴(yán)格的執(zhí)行./bin/mysqld_safe&，之后可以啟動(dòng)，啟動(dòng)的進(jìn)行如下：
mysql 4389 4243 2 22:23 pts/0 00:00:00 ./bin/mysqld --basedir=/application/mysql --datadir=/application/mysql/data --plugin-dir=/application/mysql/lib/plugin --user=mysql --log-error=/application/mysql/data/135.err --pid-file=/application/mysql/data/135.pid
可以看出用/etc/init.d/mysqld啟動(dòng)，之所以出現(xiàn)如上的錯(cuò)誤，還是配置文件的問(wèn)題，沒(méi)有找到配置的文件?？蓤?zhí)行命令 ./bin/mysqld_safe --defaults-file=/etc/my.cnf 指定已經(jīng)配好的配置文件。
