Unzip tar-xvf jdk-7u25-linux-x64.tar.gz
Move to the/opt/directory sudo mv jdk1.7.0 _ 25 // opt/
Configure Environment Variables

PATH = "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games: /usr/local/games:/opt/jdk1.7.0 _ 25/bin"
CLASS_PATH = "/opt/jdk1.7.0 _ 25/lib"

2. tomcat

Tomcat is easy to install, decompress it, move it to opt, and start and close the script under tomcat/bin/to run it.
Pay attention to permission issues.
3. mysql 5.6

Install tarpackage mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz
Unzip tar-zxvf mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz

Transfer sudo mv mysql5.6/opt/
Go to the mysql folder cd mysql5.6/
Add mysql user groups and users:

Sudo groupadd mysql
Sudo useradd-r-g mysql
Change the user and User Group of the mysql5.6 Folder:

Sudo chown-R mysql.
Sudo chgrp-R mysql.
Run the installation script:

Sudo scripts/mysql_install_db -- user = mysql
Error: Installing MySQL system tables.../bin/mysqld: error while loading shared libraries: libaio. so.1: cannot open shared object file: No such file or directory
Install libaio. so.1 and execute:
Sudo apt-get install libaio-dev
Install libaio and run the mysql installation script.
Change the permission back and only keep the data directory as a mysql user
Sudo chown-R root.
Sudo chown-R mysql data
Copy the mysql configuration file to the etc directory (global configuration)

Sudo cp support-files/my-default.cnf/etc/my. cnf
Start mysql in the Mysql5.6 directory:

/Opt/mysql5.6 $ sudo bin/mysqld_safe -- user = mysql &
Initialize the mysql password:

Sudo bin/mysqladmin-u root password '123'
Modify the basepath of mysql. server

Vim support-files/mysql. server is the current directory. The default file path is/usr/local/mysql. You can copy the files to this directory from the beginning,
Copy the mysql. server script to/etc/init. d (initialize the service)

Sudo cp support-files/mysql. server/etc/init. d/mysql. server
View the mysql running status:

Sudo service mysql. server status
Close startup:

Sudo service mysql. server start | stop
Set to mysql boot: defaults boot, remove cancel boot

Sudo update-rc.d-f mysql. server defaults | [remove]
Add the mysql command to the command or add the mysql bin directory to the environment variable.
Sudo ln-s bin/mysql/usr/local/bin/mysql
Export PATH = $ PATH:/opt/mysql5.6/bin
Allow the root user to log on remotely:

Mysql-u root-p
Log on to all hosts
Grant all privileges on *. * to root @ "%" identified by "111111" with grant option;
Specify host Login

Grant all privileges on *. * to root @ "" identified by "passw0rd" with grant option;
Authorization takes effect: flush privileges;
Supplement: an error is reported when workbench is installed. Refer to the solution below.

Cp support-files/mysql. server/etc/init. d/mysql
Chmod + x/etc/init. d/mysql
Vim mysql
# Modify the following two variables
Basedir =/home/software/mysql-5.5.20
Datadir =/home/software/mysql-5.5.20/data
Then run the update-rc.d mysql ults
# Use service mysql start to start again. The following error occurs:
# Couldn't find MySQL server (/usr/bin/mysqld_safe). The path is incorrect. You should not find mysqld_safe in/usr/bin. If you suspect that an error occurred while loading the configuration file during mysql startup, the read sequence of the mysql configuration file is as follows:
/Etc/my. cnf/etc/mysql/my. cnf/usr/local/mysql/etc/my. cnf ~ /. My. cnf
Check one by one and find that the above two values in/etc/mysql/my. cnf are incorrect. After modification, test and find that service mysql start can be used to start mysql.
