Tomcat service setup steps

I. Initialization of the environment (starting with the first graphical interface entered after installation)

Configure the server to work in command line mode

• alt + ctrl + f3 temporarily enter command line mode, effective in time
• Vim/etc/inittab Modify the bottom number 5 to 3

Close iptables and selinux

• service iptables stop temporarily closes the firewall and takes effect in time
• Chekconfig iptables off shutdown firewall service boot-up

Configure the local YUM source

• a. Put the shutdown into the CD-ROM drive
• b. Mounting CD-ROM to the system
  mount -t iso9660 /dev/cdrom /mnt/cdrom
• c. Modifying the yum configuration file

cd /etc/yum.repos.d/
mkdir back
mv * back/
cp back/CentOS-Media.repo .
vim CentOS-Media.repo
    baseurl=file://mnt/cdrom
    enabled=1
    gpgchek=0

Restart the server to display the demo effect

reboot

2. The environment needed to install tomcat

Install gcc and lrzsz

• Yum-y install gcc* install the software needed to compile the source package
• Yum-y install lrzsz installation can be uploaded and downloaded through the xshell terminal

Installing JDK

• 1. Decompress JDK package
  If there are ISO packages, mount-o loop tomcat.iso/iso/tomcat

tar -zxvf jdk.....tar.gz -C /usr/local   Unzip to the specified directory
cd /usr/local
mv jdk1.7.0_25 jdk   Modify directory name

• 2. Configuring JDK environment variables

vim /etc/profile
        //Add at the bottom of the document:
        # JDK
        export JAVA_HOME=/usr/local/jdk
        export JAVA_BIN=/usr/local/jdk/bin
        export PATH=$PATH:$JAVA_HOME/bin
        export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
        export JAVA_HOME JAVA_BIN PATH CLASSPATH
source /etc/profile Refresh environmental variables to take effect

Install Tomcat

• 1. Unzip Tomcat package to / usr/local directory

tar -zxvf apache-tomcat....tar.gz -C /usr/local    Unzip to the specified directory
cd /usr/local
mv apache-tomcat-7.0.42 tomcat    Modify directory name

• 2. Configuring Tomcat's environment variables

vim /etc/profile
        #TOMCAT
        export TOMCAT_HOME=/usr/local/apache-tomcat-7.0.37
        export PATH=$PATH:$TOMCAT_HOME/bin
source /etc/profile Refresh environmental variables to take effect

• 3. Start tomcat program

chmod 777 /usr/local/tomcat/bin/*.sh
tomcat Open: /usr/local/tomcat/bin/catalina.sh start

Install MySQL

• * Installation dependency package: yum-y install ncurses-devel
• 1. Decompression

tar -zxvf mysql-5.1.55.tar.gz -C /tmp    
cd /tmp/mysql...

• 2. Install mysql

./configure --prefix=/usr/local/mysql --with-charset=utf8 --with-collation=utf8_general_ci --with-extra-charsets=gbk,gb2312
make
make install
cp -f support-files/my-medium.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
chmod a+x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
ln -s /usr/local/mysql/bin/* /usr/local/bin/ Simplify the call path (unchangeable)
ln -s /usr/local/mysql/lib/mysql/* /usr/lib
ln -s /usr/local/mysql/include/mysql/* /usr/include/
useradd -M -s /sbin/nologin mysql Creating database users
mysql_install_db --user=mysql Initialize the database
cd /usr/local/mysql/
chown -R root:mysql .
chown -R mysql var/
service mysqld start
mysqladmin -uroot password '123456'

Three Adding MySQL Users

• create user `user'@'login address' identified by `password';
• grant permission on database. Datasheet to'user'@ login address' identified by'password';

//Enter mysql administrator user
mysql -uroot -p    
//Create user subnit to allow remote login only
create user 'subnit'@'%' identified by '123456';   
//Give remote login user subnit all permissions to view all databases
grant all on *.* to 'subnit'@'%' identified by '123456'; 
//Give users the right to log in locally
grant all on *.* to 'subnit'@'localhost' identified by '123456'; 

Note: Setting the login address to'localhost'allows only local login, not remote login; setting the login address to'%' allows any remote host to login, not local login;
Note: grant all on. to'zhangsan'@'localhost' identified by'123456'; grant all permissions for Zhang San to log in locally

Four Deployment java Warpackages

1. Add in the Host area at the bottom of the / usr/local/tomcat/conf/server.xml configuration file

vim /usr/local/tomcat/conf/server.xml

Add to

<Context path="" docBase="war Package name" debug="0" privileged="true"/>

1. Copy war into / usr/local/tomcat/webapps directory and delete ROOT directory

cp **.war /usr/local/tomcat/webapps
 rm -rf /usr/local/tomcat/webapps/ROOT

1. Restart tomcat service

/usr/local/tomcat/bin/catalina.sh start

1. The original tomcat uses 8080 port for access, changes the port to 80 using IP direct access, and also modifies the configuration of / usr/local/tomcat/conf/server.xml.
   Change 8080 to 80
