1、手动启动：
1 [root@node ~]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf & 2 [1] 15689 3 [root@node ~]# nets2018-05-06T08:10:50.238854Z mysqld_safe Logging to '/data/mysql/error.log'. 4 t2018-05-06T08:10:50.293504Z mysqld_safe Starting mysqld daemon with databases from /data/mysql 5 6 -bash: netst: command not found 7 [root@node ~]# netstat -unltp|grep 3306 8 tcp6 0 0 :::3306 :::* LISTEN 16984/mysqld 9 [root@node ~]# ps xua|grep mysqld 10 root 15689 0.2 0.0 113252 1660 pts/0 S 16:10 0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf 11 mysql 16984 1.1 14.7 2331244 275008 pts/0 Sl 16:10 0:00 /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/data/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/data/mysql/error.log --open-files-limit=65535 --pid-file=node.pid --socket=/tmp/mysql.sock --port=3306 12 root 17027 0.0 0.0 112644 952 pts/0 S+ 16:11 0:00 grep --color=auto mysqld 13 [root@node ~]#
2、手动关闭：
1 [root@node ~]# /usr/local/mysql/bin/mysqladmin -uroot -hlocalhost -proot@123 shutdown 2 mysqladmin: [Warning] Using a password on the command line interface can be insecure. 3 [root@node ~]# 2018-05-06T08:12:58.958427Z mysqld_safe mysqld from pid file /data/mysql/node.pid ended 4 5 [1]+ Done /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf 6 [root@node ~]# 7 [root@node ~]# ps xua|grep mysqld 8 root 17036 0.0 0.0 112644 952 pts/0 S+ 16:13 0:00 grep --color=auto mysqld 9 [root@node ~]#
3、shell下查看MySQL数据库下表结构：
1 [root@node ~]# mysql -uroot -hlocalhost -p -e "use mysql;select User,Host,authentication_string from user;" 2 Enter password: 3 +---------------+-----------+-------------------------------------------+ 4 | User | Host | authentication_string | 5 +---------------+-----------+-------------------------------------------+ 6 | root | localhost | *A00C34073A26B40AB4307650BFB9309D6BFA6999 | 7 | mysql.session | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | 8 | mysql.sys | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | 9 +---------------+-----------+-------------------------------------------+ 10 [root@node ~]#
注意"-e"参数的使用
