  --5. Start mysqld service, and tomcat

  cd / usr / local / hehe

  mkdir mysql_data

  # You must modify the user belongs to, oh, if you modify the mysql data file directory, then

  chown mysql: mysql mysql_data

  service mysqld start

  / Usr / local / tomcat / bin / startup.sh

  5.1 set Tomcat to start automatically

  There are a number of ways, such as setting service, or use rc.local loading.

  Modify / etc / rc.d / rc.local file:

  vim / etc / rc.d / rc.local

  Inside the increase Tomcat startup script, then save. The final results are shown below:

  [Root @ xxx bin] # cat / etc / rc.d / rc.local

  #!/ Bin / sh

  #

  # This script will be executed * after * all the other init scripts.

  # You can put your own initialization stuff in here if you do not

  # Want to do the full Sys V style init stuff.

  touch / var / lock / subsys / local

  # Start tomcat

  / Usr / local / tomcat / bin / startup.sh

  Way, of course, start other programs can also be used in this way, but it is a little soil, but can not use chkconfig to configure and invoke (That did not use to install Service.)
