Configure Tomcat, MySQL boot on Linux

1. Tomcat Boot up

Method One, modify the system files (already tried, can)

1. Modify/etc/rc.d/rc.local
Vi/etc/rc.d/rc.local

2. Add the following two lines of script, remember the two lines, only the second line is not, you must add the first row. At the end of the/etc/rc.d/rc.local file, add:

Export java_home=/usr/java/jdk1.7.0_60
/usr/local/tomcat/bin/startup.sh start
Description:/usr/java/jdk1.7.0_60 is the JDK installation directory
/usr/local/tomcat is a tomcat-installed directory

3. Note: Modify the rc.local file to be executable
chmod +x rc.local

Method Two,

Shell script Startup

Setting up the boot-up service in Linux requires a/ETC/RCX.D under the load. In addition, you need to/etc/init.d some startup scripts. In fact, it is very simple to export the required environment variables, such as Java_home,jre_home, Catalina_home, Catalina_base and so on, and then directly call $catalina_home/bin/ Startup.sh will be able to start successfully.

The first step: we create a new file under/ETC/INIT.D Tomcat (need to operate under root privileges)

1. Vi/etc/init.d/tomcat

Write down the following code, Tomcat self-launching script:

2. #!/bin/sh
4. # chkconfig: 345
6. # Description:auto-starts Tomcat
8. #/ETC/INIT.D/TOMCATD
10. # Tomcat Auto-start
12. # Source function library.
14. #. /etc/init.d/functions
16. # source Networking configuration.
18. #. /etc/sysconfig/network
20. retval=0
22. Export JAVA_HOME=/USR/JAVA/JDK1. 7.0_60
24. Export JRE_HOME=/USR/JAVA/JDK1. 7.0_60/jre
26. Export Catalina_home=/usr/local/tomcat
28. Export Catalina_base=/usr/local/tomcat
30. Start ()
32. {
34. if [-f $CATALINA _home/bin/startup.sh];
36. Then
38. echo $"Starting Tomcat"
40. $CATALINA _home/bin/startup.sh
42. Retval=$?
44. echo "OK"
46. return $RETVAL
48. Fi
50. }
52. Stop ()
54. {
56. if [-f $CATALINA _home/bin/shutdown.sh];
58. Then
60. echo $"Stopping Tomcat"
62. $CATALINA _home/bin/shutdown.sh
64. Retval=$?
66. Sleep 1
68. PS-FWWU Root | grep tomcat|grep-v grep | Grep-v PID | awk ' {print $} ' |xargs Kill-9
70. echo "OK"
72. # [$RETVAL-eq 0] && rm-f/var/lock/ ...
74. return $RETVAL
76. Fi
78. }
82. Case "$" in
84. Start
86. Start
88. ;;
90. Stop
92. Stop
94. ;;
98. Restart
100. echo $"restaring Tomcat"
102. $0 Stop
104. Sleep 1
106. $0 Start
108. ;;
110. *)
112. echo $"Usage: $ {start|stop|restart}"
114. Exit 1
116. ;;
118. Esac
120. Exit $RETVAL

Here is a special reminder to note that this sentence Ps-fwwu root | grep tomcat|grep-v grep | Grep-v PID | awk ' {print $} ' |xargs kill-9, the person familiar with the Linux command should be aware of the meaning of this sentence, here simply say the first half, query the root user tomcat process PID, personal changes according to the actual situation.

Step two: After you save the exit, add executable permissions to it

1. chmod +x/etc/init.d/tomcat

Step Three: Mount

Connect the shell file link to the/etc/rc2.d/directory. The numbers in the/etc/rcx.d/directory for Linux represent the different run level, which is the order in which the boot starts, Ubuntu9.10 There are 0-5 six level, can not be casually connected to other directories, it may be in that directory when the program started Tomcat needed to some of the library has not been loaded, with the ln command link tomcat links Past: sudo ln-s/etc/init.d/ Tomcat/etc/rc2.d/s16tomcat. The naming rules under the RCX.D directory are very specific, more different needs may be the beginning of s, may also be the beginning of K, after the numbers represent their starting order, detailed look at the Readme file in their respective directories.

1. Ln-s/etc/init.d/tomcat/etc/rc2.d/s16tomcat

Fourth step: Set the script to boot from

Set this script to automatically execute when the system starts, and stop automatically when the system shuts down, using the following command:

1. Chkconfig--add Tomcat

Fifth Step: Verify

Execute sudo reboot. After rebooting, you will find that Tomcat has run successfully.

Digression: After adding this script we start, stop, restart Tomcat to use the command directly

1. Service Tomcat Start
2. Service Tomcat Stop
3. Service Tomcat Restart

Other tomcat settings commands are: Chkconfig--list Tomcat chkconfig Tomcat on, and you can try to find out what the effect is.

Mysql

Command echo "service mysqld start" >>/etc/rc.local

Or go to/etc/directory, direct vim rc.local edit rc.local file, add "service mysqld start" in the last line, save exit

You can use chkconf--list
