Set the apache httpd service to start automatically under Linux

linux server to build svn+apache+ssl deployment environment:
1. svn installation and use under linux reference link: linux server svn installation and version control .
2. svn configuration http access service reference link under linux: linux server svn configuration http access .
3 , svn configuration https access service reference link under linu: linux server deployment svn https access .
4, linux svn setting boot self-starting reference link: linux svn setting booting self-starting .

1. Introduction

   Svn is often built locally. The environment of the local server is also extremely unstable, and it is difficult to avoid power outages. When the server is started, it is very troublesome to restart various services.
   The following is the svn self-starting setting under linux, record it for your own use later.

Two, linux self-starting settings

Check the server version command: uname -a
first explain my version, different versions may be slightly different

The linux service startup scripts are mostly placed etc/init.din folders

2.1 Create httpd self-starting file

# 进入目录
cd /etc/init.d
# 创建自启动脚本文件
touch appache-httpd
ls -lt

2.2 Edit the appache-httpd script file

Edit the file appache-httpd:

gedit appache-httpd

Write the startup script:

#!/bin/bash
#
# created by rmling, 2022/05/05
#
# apache-httpd    Startup script for the Apache HTTP Server
#
# chkconfig: 345 85 15

#           HTML files and CGI.

# pidfile: /run/httpd/httpd.pid
# Source function library.

HTTPD_LANG=${HTTPD_LANG-"C"}

# mod_ssl needs a pass-phrase from the user.

apahectl=/usr/sbin/apachectl
httpd=${HTTPD-/usr/sbin/httpd}
prog=httpd
pidfile=${PIDFILE-/run/httpd/httpd.pid}
lockfile=${LOCKFILE-/run/lock/subsys/httpd}
RETVAL=0
# The semantics of these two functions differ from the way apachectl does
# things -- attempting to start while running is a failure, and shutdown
# when not running is also a failure.  So we just do it the way init scripts
# are expected to behave here.
start() {
        echo -n $"Starting $prog: "
        LANG=$HTTPD_LANG daemon $httpd $OPTIONS
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && touch ${lockfile}
        return $RETVAL
}
# When stopping httpd a delay of >10 second is required before SIGKILLing the
# httpd parent; this gives enough time for the httpd parent to SIGKILL any
# errant children.
stop() {
    echo -n $"Stopping $prog: "
    killproc -d 10 $httpd
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
}
reload() {
    echo -n $"Reloading $prog: "
    if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
        RETVAL=$?
        echo $"not reloading due to configuration syntax error"
        failure $"not reloading $httpd due to configuration syntax error"
    else
        killproc $httpd -HUP
        RETVAL=$?
    fi
    echo
}
# See how we were called.

  start)
    start
    ;;
  stop)
    stop
    ;;

        status $httpd
    RETVAL=$?
    ;;
  restart)
    stop
    start
    ;;
  condrestart)
    if [ -f ${pidfile} ] ; then
        stop
        start
    fi
    ;;
  reload)
        reload
    ;;

    $apachectl $@
    RETVAL=$?
    ;;

    echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
    exit 1

exit $RETVAL

The following options are assigned according to their actual installation conditions:
#config: /etc/httpd/conf/httpd.conf
apahectl=/usr/sbin/apachectl
httpd= $HTTPD-/usr/sbin/httpdpidfile=${PIDFILE-/run/httpd/httpd.pid}
lockfile=${LOCKFILE-/run/lock/subsys/httpd}

2.3 Assign permissions

#执行如下命令，将该脚本标记为可执行文件(添加可执行的权限)
 chmod +x /etc/init.d/appache-httpd

2.4 Set the startup

chkconfig --add appache-httpd
#执行如下命令，查看是否添加成功了
chkconfig httpd on 

Note: If -> service does not support chkconfig, check the startup script above carefully

2.5 View status

#查看状态
chkconfig --list appache-httpd

At this time, all levels are off, and it is set to run at all levels:

chkconfig --level 0123456 appache-httpd on

2.6 Service start

service httpd start

3. Test

Immediately restart the server:

shutdown -r now 

Execute the command after reboot:

#查看https是否启动成功
netstat -ntpl|grep 443
