1.1UninstallLinuxSystem self-installingOpenJdkTomcat,MySQL

Use the yum or rpm command to see if the system has its own jdk,Tomcat, mysql, command format, with jdk as an example:

Yum command: yum list installed |grep jdk

RPM Command:rpm –qa|grep jdk (query rpm package)

If the system has self-installed these software, in order to ensure consistent version, you need to uninstall:

Yum command:yum remove + Package name manually select y or n

Yum–y Remove + package name Auto Select y, fully automatic

RPM command:rpm-e package name (unload rpm package)

1.2installationMySQL

1. Upload the mysql software package to the Linux machine, using the yum command or rpm command to install, the document is using the rpm command.

Package: mysql-server-5.5.40-1.linux2.6.x86_64.rpm

MYSQL-CLIENT-5.5.40-1.LINUX2.6.X86_64.RPM,

2. Start MySQL

Service MySQL start start MySQL

Service MySQL stop stop MySQL

Things to keep in mind

1,the first installation, the database default password is empty, so you need to modify the database password.

Login mysql command: mysql –u User (default is root) –p Password

Example:mysql-h 192.168.1.41-u test1234-ptest1234

UPDATE user SET Password=password ("test1234");

Flush privileges;

When you open a mysql command, log in to MySQLand view the database password is already in effect.

2.Open Remote login permissions for the database

Method: After logging in to MySQL , changethe "host " in the "User" tablein the "MySQL" database. "Item, from localhost instead " % "

Use MySQL

Update user set host= '% ' where user= ' root ';

Selete host,user from user;

Flush privileges; --- make changes effective

After modification, add parameters to the MySQL database when the "-H database is located on the machine's IP"

3,max_allowed_packet parameter value is changed to greater than 16M.

OpenCms The installation will verify Max_allowed_packet , if the value is less than 16M , OpenCms Unable to install, error

Modification Method:

1> go to MySQL server

2> run in the MySQL command line

Set Global Max_allowed_packet = 2*1024*1024*10

3> then shut down this mysql server link and then enter.

Show VARIABLES like '%max_allowed_packet% ';

See if the next max_allowed_packet is edited successfully

4. Turn off the firewall
