Linux配置环境变量自动识别软件命令和设置开机启动软件

作者:互联网

一、配置环境变量

1、Linux的环境变量是保存在变量PATH中(window 也是保存在PATH中),可通过命令 echo $PATH 输出查看

2、将刚安装好的Nginx软件增加到环境变量中,是Nginx命令可以直接使用

#编辑环境变量文件
vim /etc/profile

#增加安装目录到环境变量
export PATH=/usr/local/nginx/sbin/:$PATH

#保存文件退出后,重新加载环境变量文件
source  /etc/profile

3、这样Linux命令可以可以直接运行Nginx命令操作了

 

二、Linux重启,软件开机启动(Centos6.5)

1、在linux系统的/etc/init.d/目录下创建nginx文件(/etc/init.d/是linux启动时运行脚本目录)

vim /etc/init.d/nginx

2、在脚本中添加如下命令(注意你Nginx脚本的安装路径,替换你的安装路径)

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
if [ -z "`grep $user /etc/passwd`" ]; then
   useradd -M -s /bin/nologin $user
fi
options=`$nginx -V 2>&1 | grep 'configure arguments:'`
for opt in $options; do
   if [ `echo $opt | grep '.*-temp-path'` ]; then
       value=`echo $opt | cut -d "=" -f 2`
       if [ ! -d "$value" ]; then
           # echo "creating" $value
           mkdir -p $value && chown -R $user $value
       fi
   fi
done
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
    rh_status_q && exit 0
    $1
    ;;
stop)
    rh_status_q || exit 0
    $1
    ;;
restart|configtest)
    $1
    ;;
reload)
    rh_status_q || exit 7
    $1
    ;;
force-reload)
    force_reload
    ;;
status)
    rh_status
    ;;
condrestart|try-restart)
    rh_status_q || exit 0
        ;;
 *)
    echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
    exit 2
esac

3、使用chkconfig进行管理,将nginx服务加入启动项管理列表

chkconfig --add /etc/init.d/nginx

4、测试Nginx

/etc/init.d/nginx start
/etc/init.d/nginx stop
