How to Set auto-start for cenos startup

There are two main ways to enable cenos to enable auto-start

1. Add the Startup Program command to the/etc/rc. d/rc. Local folder.

Set eg1. start MySQL at startup

Vim/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 don't # Want to do the full sys V style init stuff.
Touch/var/lock/subsys/local -- Update access time and modification time/usr/local/MySQL/bin/MySQL start

Eg2. set startup Tomcat

Vim/etc/rc. d/RC. local # This script will be executed * after * all the other init scripts. # You can put your own initialization stuff in here if you don't # Want to do the full sys V style init stuff. export catalina_base =/usr/local/tomcat/export catalina_home =/usr/local/tomcat/export catalina_tmpdir =/usr/local/tomcat/temp export jre_home =/usr/Java/jdk1.7.0 _ 55/
# Tomcat self-start
/Usr/local/tomcat/bin/startup. Sh start
Touch/var/lock/subsys/local -- if this sentence exists in the document, you do not need to write it again.

2. Add the prepared STARTUP script to the/etc/rc. d/init. d/directory, and run the command chkconfig to set the startup. (Recommended)

Chkconfig Function Description: Check and set various services of the system.

Syntax: chkconfig [-- add] [-- del] [-- list] [System Service] Or chkconfig [-- level <level code>] [System Service] [ON/OFF/Reset]

-- Add Add add service

-- Del Delete Service

-- List to view the startup status of each Service

Set redis auto-start in eg1.

To start redis, you need to run the redis-server and redis. conf files.

Script: Vim/etc/init. d/redis

Vim/etc/init. d/redis
# Chkconfig: 2345 10 90 # Description: Start and Stop redis Path =/usr/local/bin:/sbin:/usr/bin: /bin redisport = 6379 # exec =/usr/local/redis/src/redis-server # redis_cli =/usr/local/redis/src/ redis-cli # The actual environment depends on pidfile =/var/run/redis. pidconf = "/usr/local/redis. conf "# actual environment depends on Case" $1 "in START) If [-F $ pidfile] Then ECHO" $ pidfile exists, process is already running or crashed. "Else echo "Starting redis server..." $ exec $ conf Fi if ["$? "=" 0 "] Then ECHO" redis is running... "fi; stop) If [! -F $ pidfile] Then ECHO "$ pidfile exists, process is not running. "Else pid = $ (cat $ pidfile) echo" stopping... "$ redis_cli-p $ redisport shutdown while [-x $ (pidfile)] Do echo" waiting for redis to shutdown... "Sleep 1 done echo" redis stopped "fi; restart | force-Reload) $ {0} Stop $ {0} start; *) echo" Usage: /etc/init. d/redis {START | stop | restart | force-Reload} "> & 2 exit 1 esac

# Modifying permissions and owner

chown root.root  /etc/rc.d/init.d/redischmod  755 /etc/rc.d/init.d/redis

# Put redis into the cenos startup management system

chkconfig --add redis

# Set auto-start upon startup

chkconfig redis on

# Test redis startup

redis-cli redis 127.0.0.1:6379> set foo 123OKredis 127.0.0.1:6379> get foo"123"redis 127.0.0.1:6379> exit

Eg2.fastdfs auto-start

[[email protected] ~]# cp /usr/local/src/FastDFS/init.d/fdfs_storaged /etc/init.d/[[email protected] ~]# chkconfig --add fdfs_storaged[[email protected] ~]# chkconfig fdfs_storaged on[[email protected] ~]# service fdfs_storaged start

############################## Use the chkconfig command to set Tomcat for Automatic startup ############################

1. Modify the start. Sh file.

Vim/home/wwwroot/tomcat_wiki/bin/startup. Sh

Add the following content to the file header:

#! /Bin/sh

# Chkconfig: 2345 97 00 # Description: Tomcat auto start # processname: Tomcat

2. Modify the Catalina. Sh file.

Vim/home/wwwroot/tomcat_wiki/bin/Catalina. Sh

Add the following content:

Export export =/home/wwwroot/tomcat_wiki export catalina_home =/home/wwwroot/tomcat_wiki export =/home/wwwroot/tomcat_wiki/temp export jre_home =/usr/local/jdk1.6.0

3. Create a link file

Ln-S/home/wwwroot/tomcat_wiki/bin/startup. sh/etc/init. d/tomcat

4. Modify permissions

Chmod + x Tomcat

5. Add startup

Chkconfig-add Tomcat (two minus signs before "add)

Chkconfig Tomcat on

6. Check

Service Tomcat start

Or reboot
