Install JDK1.7 + tomcat7 + mysql5.5 on centos7

Install JDK1.7 + tomcat7 + mysql5.5 on centos7

1. Install JDK first

Step 1. Extract the tar package in the current directory

[Root @ localhost usr] # tar-xzvf jdk-7u25-linux-x64.tar.gz

Step 2: Configure Environment Variables

Add it under the etc/profile file

Export JAVA_HOME =/usr/java/jdk1.7.0 _ 25

Export CLASSPATH =/usr/java/jdk1.7.0 _ 25/lib

Export PATH = $ JAVA_HOME/bin: $ PATH

Run the following command after adding environment variables:

[Root @ localhost ~] # Source/etc/profile make the configuration file take effect immediately.

Verify that environment variables take effect

[Root @ localhost ~] # Echo $ JAVA_HOME

/Usr/java/jdk1.7.0 _ 25

[Root @ localhost ~] # Echo $ PATH

/Usr/java/jdk1.7.0 _ 25/bin:/usr/kerberos/sbin:/usr/kerberos/bin

:/Usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin: /root/bin

[Root @ localhost ~] # Echo $ CLASSPATH

/Usr/java/jdk1.7.0 _ 25/lib

Step 3: run the java-version command to verify whether the installation is successful.

[Root @ localhost tmp] # java-version

Java version "1.7.0 _ 25"

Java (TM) SE Runtime Environment (build 1.7.0 _ 25-b15)

Java HotSpot (TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

The above information indicates that the installation is successful.

Ii. install Tomcat 7

In fact, tomcat does not need to be installed. Download the tar package of tomcat directly, use tar-xvzf tomcat7.xx.tar.gz to decompress the package, and directly upload the war file of the java project to the webapps directory of tomcat, go to the bin directory under the tomcat directory and run the command to start tomcat :. /startup. sh is that simple.

Iii. Install mysql

1. Install cmake

[Root @ localhost/] # yum install cmake

[Root @ localhost ~] #/Usr/sbin/groupadd mysql

[Root @ localhost ~] #/Usr/sbin/useradd-g mysql

[Root @ localhost ~] # Tar xvf mysql-5.5.16.tar.gz
[Root @ localhost ~] # Cd mysql-5.5.16/


[Root @ localhost ~] # Cmake-DCMAKE_INSTALL_PREFIX =/usr/local/mysql \
-DMYSQL_UNIX_ADDR =/tmp/mysql. sock \
-DDEFAULT_CHARSET = utf8 \
-DDEFAULT_COLLATION = utf8_general_ci \
-DWITH_EXTRA_CHARSETS: STRING = utf8, gbk \
-DWITH_MYISAM_STORAGE_ENGINE = 1 \
-DWITH_INNOBASE_STORAGE_ENGINE = 1 \
-DWITH_MEMORY_STORAGE_ENGINE = 1 \
-DWITH_READLINE = 1 \
-DENABLED_LOCAL_INFILE = 1 \
-DMYSQL_DATADIR =/var/mysql/data \
-DMYSQL_USER = mysql

If the following error is reported during this step

-- MySQL 5.5.16
-- Cocould NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline. cmake: 83 (MESSAGE ):
Curses library not found. Please install appropriate package,

Remove CMakeCache.txt and rerun cmake. On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

Solution:

[Root @ localhost mysql] # yum install ncurses-devel.x86_64
[Root @ localhost mysql] # make clean
[Root @ localhost mysql] # rm-rf CMakeCache.txt
[Root @ localhost mysql] # cmake.-LH

To start mysqld at boot time you have to copy
Support-files/mysql. server to the right place for your system

Please remember to set a password for the MySQL root USER!
To do so, start the server, then issue the following commands:

./Bin/mysqladmin-u root password 'new-password'
./Bin/mysqladmin-u root-h localhost. localdomain password 'new-password'

Alternatively you can run:
./Bin/mysql_secure_installation

Which will also give you the option of removing the test
Databases and anonymous user created by default. This is
Stronugly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon:
Cd ..;./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
Cd./mysql-test; perl mysql-test-run.pl

Please report any problems with the./bin/mysqlbug script!

Set a password for mysql. The default password for mysql is null.

Log on to the mysql system,
# Mysql-uroot-p
Enter password: [Enter the original password] the default password is blank. Press Enter.
Mysql> use mysql;
Mysql> update user set password = passworD ("test") where user = 'root ';
Mysql> flush privileges;
Mysql> exit;

After mysql is installed, remote access is disabled by default.

Log on to the mysql system,
# Mysql-uroot-p

Enter password: After the password is entered

Mysql> use mysql;

Mysql> update user set host = '%' where user = 'root ';

Mysql> select host, user from user;

Mysql> flush privileges;
Mysql> exit;

This is the end of the process. The first write is messy and I hope to help you.

Ps:

Run the rpm-ql software name to check the software installation location.

Rpm-qa | grep software name to check whether the software is installed
