一、连接MySQL数据库1连接：2mysqlhhostuuserp34常见错误：5ERROR2002(HY000):Can'tconnecttolocalMySQLserverthroughsocket'/tmp/my

问题一常见502Bad的问题root@localhost~vi/usr/local/nginx/conf/vhost/test.com.conf将50fastcgi_passunix:/tmp/phpfcgi.sock;改错为50

方法一：sudokillall9neteasecloudmusic这种方法，必须要写全称。sudoneteasecloudmusicQStandardPaths:XDG_RUNTIME_DIRnotset,defaultingto'/tmp/runtimeroot'0

1.05Ansible远程执行脚本首先创建一个shell脚本vim /tmp/test.sh //加入内容!/bin/bashechodate/tmp/ansible_test.txt然后把该脚本分发到各个机器上ansibletesthostmcop

一、修改配置文件my.cnf服务器A（172.16.16.70）配置如下server\_id70socket/tmp/mysql.sockinnodb\_buffer\_pool\_size10Gcharactersetserverutf8log\_binmysqlbinexpire\_l

SET命令用途：可以设置shell的执行方式，不带参数时输出环境变量。setabCdefhHklmnpPtuvx注：1.表示设置参数2.表示取消设置参数示例：tmp"niceday"$tmpnice

在mysql命令行下执行以下sql语句:mysqlselect\fromxi\_tableintooutfile’/tmp/test.xls’;一句话搞定。linux系统尽量导出在/tmp目录下，不会涉及读写权限问题！导出为txt文件：select\fromxi\_tableintooutfile’/tmp/

1、把下载的JDK软件包上传到服务器/tmp路径下，然后复制到/usr/local路径下进行解压。进入/usr/local路径下cd/usr/local将文件复制到此路径下cp/tmp/jdk7u79linuxx64.tar.gz./解压tarzxvfjdk7u79li

1、二进制日志备份    mysqlbinlogbinlog.000001/tmp/bak.sql//备份binlog.000001二进制文件，在tmp目录下生成bak.sql文件。2、二进制日志恢复    2.1SQL文件恢复        mysqlurootproote"source/tmp/bak.s

1.类型转换代码Int32转换为int16会丢失精度，这是总所周知的，但是具体如何丢失精度的，请看下面的代码：vartmp1int32123424021vartmp2int16vartmp3uint16tmp2int16(tmp1)tmp3uint16(t
