Shell腳本習(xí)題：nginx服務(wù)啟動(dòng)程序
使用源碼包安裝的Nginx沒辦法使用”service nginx start”或”/etc/init.d/nginx start”進(jìn)行操作和控制，所以寫了以下的服務(wù)控制腳本。
創(chuàng)新互聯(lián)公司專注于企業(yè)成都營銷網(wǎng)站建設(shè)、網(wǎng)站重做改版、皋蘭網(wǎng)站定制設(shè)計(jì)、自適應(yīng)品牌網(wǎng)站建設(shè)、H5網(wǎng)站設(shè)計(jì)、商城網(wǎng)站制作、集團(tuán)公司官網(wǎng)建設(shè)、成都外貿(mào)網(wǎng)站建設(shè)、高端網(wǎng)站制作、響應(yīng)式網(wǎng)頁設(shè)計(jì)等建站業(yè)務(wù)，價(jià)格優(yōu)惠性價(jià)比高，為皋蘭等各大城市提供網(wǎng)站開發(fā)制作服務(wù)。
選項(xiàng)有：
start 啟動(dòng)
stop 停止
reload 重載
restart 重啟
status 狀態(tài)
test 檢查配置文件
腳本一
創(chuàng)建腳本文件并添加執(zhí)行權(quán)限
touch /etc/init.d/nginx
chmod +x /etc/init.d/nginx
編寫腳本內(nèi)容

將腳本添加到系統(tǒng)服務(wù)并設(shè)置開機(jī)啟動(dòng)
chkconfig --add nginx
chkconfig --level 3 nginx on
腳本二
[root@localhost ~]# cd /usr/local/nginx/conf/
[root@localhost conf]# ls
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
備份主配置文件
[root@localhost conf]# cp nginx.conf nginx.conf.origin
[root@localhost conf]# vim nginx.conf
去除#pid logs/nginx.pid;前面#號(hào)
[root@localhost conf]# netstat -anpt | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19108/nginx
[root@localhost conf]# kill -3 19108
[root@localhost conf]# netstat -anpt | grep 80
[root@localhost conf]# nginx
[root@localhost conf]# netstat -anpt | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19864/nginx
[root@localhost conf]# cd ../logs/
[root@localhost logs]# ls
access.log error.log nginx.pid
[root@localhost logs]# cat nginx.pid

編輯寫服務(wù)腳本
[root@localhost ~]# vim /etc/init.d/nginx
可以使用的選項(xiàng)有：
start 啟動(dòng)
stop 停止
reload 重載
restart 重啟
status 狀態(tài)
test 檢查配置文件
#!/bin/bash
#chkconfig: 2345 99 20

case "$1" in

else
$PROG

stop)
if [ -f $PIDF ];
then
kill -3 $(cat $PIDF)
rm -f $PIDF
else
echo "Nginx正在停止…"

$0 stop
$0 start

reload)
if [ -f $PIDF ];
then
kill -1 $(cat $PIDF)
else
echo "Nginx正在停止…重新加載"

status)
if [ -f $PIDF ];
then
echo "Nginx正在運(yùn)行"
else
echo "Nginx停止"

echo "Usage: $0 (start|stop|restart|reload|status)"
exit 1
esac
exit 0
腳本文件并添加執(zhí)行權(quán)限
[root@localhost ~]# chmod +x /etc/init.d/nginx
將腳本添加到系統(tǒng)服務(wù)并設(shè)置開機(jī)啟動(dòng)
[root@localhost ~]# chkconfig --add nginx
添加為服務(wù)啟動(dòng)項(xiàng)
[root@localhost ~]# chkconfig --list nginx
nginx 0:關(guān)閉 1:關(guān)閉 2:啟用 3:啟用 4:啟用 5:啟用 6:關(guān)閉
[root@localhost ~]# chkconfig --level 3 nginx on
測試腳本是否能夠執(zhí)行
[root@localhost ~]# service nginx start
Nginx正在運(yùn)行…
[root@localhost ~]# service nginx restart
[root@localhost ~]# service nginx stop
[root@localhost ~]# service nginx stop
Nginx正在停止…
[root@localhost ~]# service nginx start
[root@localhost ~]# service nginx status
Nginx正在運(yùn)行
