HomeOperation and MaintenanceNginxHow to install Nginx service with one click using Shell script

话不多少,内容如下:

#!/bin/bash
#Nginx版本
ver=nginx-1.$2.$3
# 安装目录
in_dir="/app/$ver"
#软件存放目录
dl_dir="/server"
#最终运行目录
run_dir=/app/nginx
if [ ! -d $in_dir ];then
    mkdir -p $in_dir
fi
if [ ! -d $dl_dir ];then
    mkdir $dl_dir
fi
##安装nginx
function nginx_install (){
yum -y install gcc gcc-c++ pcre-devel zlib-devel openssl-devel 
if [ $? -eq 0 ]
then
    curl  "http://nginx.org/download/$ver.tar.gz" -o $dl_dir/$ver.tar.gz && \ 
    useradd -M -s /sbinlogin nginx  && \
    tar xf $dl_dir/$ver.tar.gz -C $dl_dir  && \
    cd $dl_dir/$ver
    ./configure  --prefix=$in_dir --user=nginx --group=nginx  && \ 
    make  && make install 
fi
}
function nginx_init (){
  ln -s $in_dir $run_dir
}
function nginx_start (){
  ps -ef |grep nginx |grep master
  if [ $? = 0  ];then
        echo "Nginx is Running."
  else
        if [ ! -e $run_dir/sbin/nginx ];then
        nginx_init
        fi
	$run_dir/sbin/nginx
        sleep 5
        ps -ef |grep nginx |grep master
        if [ $? = 0  ];then
        echo "Nginx Start successfully."
        else
        echo "Nginx Failed to Start."
	fi
  fi
}
function nginx_stop (){
	$run_dir/sbin/nginx -s quit	
        sleep 5
        ps -ef |grep nginx |grep master
        if [ $? != 0  ];then
	    echo "Nginx Stop successfully."
        else
            echo "Nginx Failed to Stop."
	fi
}
function nginx_reload (){
	$run_dir/sbin/nginx -s reload 
}
main(){
  nginx_install
  nginx_start
}
case $1 in 
install)
	nginx_install
	nginx_init
	nginx_start
	;;
start)
	nginx_start
	;;
stop)
	nginx_stop
	;;
restart)
	nginx_stop
	nginx_start
	;;
reload)
	nginx_reload
	;;
*)
	echo "使用方法"
	echo "$0 start|stop|restart|reload"	
	echo "安装方法"
	echo "$0 install <版本号> <小版本号>  例如:$0 install 19 3 下载的就是1.19.3版本 "
	;;
esac
#if [ $# = 0 ];then
#	echo  "使用 $0 后面加上小版本号进行部署:例如 $0 19 3 下载的就是1.19.3版本"
#else
#	echo "下载版本:1.$2.$3"
#	echo "安装目录:$in_dir"
#	echo "下载目录:$dl_dir"
#	echo "Nginx installation..." 
#        nginx_install
#        if [ $? != 0 ];then
##	echo "Ngins installation Failed."
#	else 
#        nginx_init
#        nginx_start
#        fi	
#fi

这个脚本可以实现用户自己选择想要安装的Nginx版本

比如我想装一个nginx-1.16.1版本,可以这样做:

sh install_nginx.sh install 16 1

当然,如果你开始并不知道使用方法,直接执行了脚本,没关系,有提示:

[root@localhost ~]# sh install_nginx.sh
使用方法
install_nginx.sh start|stop|restart|reload
安装方法
install_nginx.sh install <版本号> <小版本号>  例如:install_nginx.sh install 19 3 下载的就是1.19.3版本

瞧,不光告诉了你怎么使用它安装服务,还可以直接运行脚本进行管理当你刚安装完成的时候默认是启动的,你可以使用脚本进行关闭或重启:

[root@localhost ~]# sh install_nginx.sh stop
Nginx Stop successfully.
[root@localhost ~]# sh install_nginx.sh reload

然后你可以修改配置后进行开启:

[root@localhost ~]# sh install_nginx.sh start
root       4236      1  0 14:23 ?        00:00:00 nginx: master process /app/nginx/sbin/nginx
Nginx Start successfully.

查看它的状态,看它是否在运行:

[root@localhost ~]# ss -utpln | grep nginx
tcp    LISTEN     0      128       *:80                    *:*                   users:(("nginx",pid=4238,fd=6),("nginx",pid=4236,fd=6))

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
