Method 1: Go to the MySQL installation directory and open the MySQL configuration file my. ini or my. CNF to find max_connections = 100 and change it to max_connections = 1000 to restart MySQL.
Method 2: the maximum number of connections of MySQL is 100 by default. Cli

Method 1:
Go to the MySQL installation directory and open the MySQL configuration file my. ini or my. CNF to find max_connections = 100 and change it to max_connections = 1000 to restart MySQL.
Method 2:

IntroducedWe have developed a tax calculator, after entering the salary, printing the tax payable.A tax calculation formula:
Taxable income = Salary amount-Various social insurance costs-starting point (3500 yuan)
Taxable amount = Taxable income x tax Rate-Calculator deduction
Each of the social insurance costs we set in this procedure is 0, do not consider.The tax rate and the Calculator deduction number corresponding table:

Recently established in the lab's network environment, all host labs are connected via a switch. Want to be a gateway through the server (single card), using the Mentohust authentication extranet, and then other hosts in the intranet through this gateway to connect to the external network.1. First use mentohust on the server to connect to the extranet, and then enter the Ifconfig command at the terminal to view the acquired extranet IP:Eth0 Link encap: Ethernet Hardware address B8:AC:6F:D8
MTU is the abbreviation of Maximumtransmissionunit, is the largest packet of packets on the network, most network device MTU is 1500,MTU unit is byte, if the MTU of the machine than the MTU of the gateway, large packets will be removed from the transmission, This will result in a lot of packet fragmentation, increase the packet loss rate, reduce network speed.
By setting the MTU of this machine to be smaller or the same than the MTU of the gateway, t
Copy Code code as follows:

var $inputs = $ (' Input[type=button] ')
. Delay (500)
. Queue (function () {$ (this). Hide (). Dequeue ();})

The above code lets the button in the page Hide 500 milliseconds after the page is loaded, and then displays it in 1500 milliseconds.
