shell脚本实战之部署nginx脚本实例

yum install -y wget gzip tar make gcc
## 安装依赖包
yum install -y pcre pcre-devel zlib-devel
## 下载需要的安装包
wget -c http://nginx.org/download/nginx-1.21.6.tar.gz -P /usr/src/
cd /usr/src/
ls -l nginx-1.21.6.tar.gz
tar -xzvf nginx-1.21.6.tar.gz
## 解压
cd nginx-1.21.6/
useradd -s /sbin/nologin www -M
##开始编译
./configure --prefix=/usr/local/nginx/ --user=www --group=www --with-http_stub_status_module
make
make install
ls -l /usr/local/nginx/
/usr/local/nginx/sbin/nginx
ps -ef|grep nginx
netstat -tnlp|grep 80
启动
setenforce 0
systemctl stop firewalld.service

## 把需要的常量提前写好
NGX_VER="1.21.6"
NGX_YUM="yum install -y"
NGX_SRC="nginx-$NGX_VER"
NGX_DIR="/usr/local/nginx"
NGX_SOFT="nginx-$NGX_VER.tar.gz"
NGX_URL="http://nginx.org/download"
NGX_ARGS="--user=www --group=www --with-http_stub_status_module"
$NGX_YUM wget gzip tar make gcc
$NGX_YUM pcre pcre-devel zlib-devel
## 下载或者用到常量的时候直接调用
wget -c $NGX_URL/$NGX_SOFT -P /usr/src/
cd /usr/src/
ls -l $NGX_SOFT
tar -xzvf $NGX_SOFT
cd $NGX_SRC/
useradd -s /sbin/nologin www -M
## 开始编译，不用写的特别长，直接用常量地址
./configure --prefix=$NGX_DIR/ $NGX_ARGS
make
make install
ls -l $NGX_DIR/
$NGX_DIR/sbin/nginx
ps -ef|grep nginx
netstat -tnlp|grep 80
setenforce 0
systemctl stop firewalld.service

## 定义常量
NGX_VER="$1"
NGX_YUM="yum install -y"
NGX_DIR="/usr/local/nginx"
NGX_SOFT="nginx-${NGX_VER}.tar.gz"
NGX_URL="http://nginx.org/download"
NGX_ARGS="--user=www --group=www --with-http_stub_status_module"

if [ $# -eq 0 ];then
        echo -e "\033[32m-------------------\033[0m"
        echo -e "\033[32mUsage:{/bin/sh $0 1.12.2|1.23.0|help}\033[0m"
        exit
fi
if [ $1 == "help" -o $1 == "-h" ];then
        echo -e "\033[32m-------------------\033[0m"
        echo -e "\033[32mUsage:{/bin/sh $0 1.12.2|1.23.0|help}\033[0m"
        exit
fi
## 判断某些目录是否存在
if [ ! -f $NGX_DIR/sbin/nginx ];then
        $NGX_YUM wget gzip tar make gcc
        $NGX_YUM pcre pcre-devel zlib-devel
        ## 下载包，其实这里我们也可以判断是否下载成功
        wget -c $NGX_URL/$NGX_SOFT -P /usr/src/
        cd /usr/src/
        ls -l $NGX_SOFT 
        tar -xzvf $NGX_SOFT 
        cd nginx-$NGX_VER/
        ## 这些路径我们都需要判断是否存在
        useradd -s /sbin/nologin www -M
        ## 开始编译
        ./configure --prefix=$NGX_DIR/ $NGX_ARGS 
        make
        make install
        ## 编译成功是否可以提示
        ls -l $NGX_DIR/
        $NGX_DIR/sbin/nginx
        ps -ef|grep nginx
        netstat -tnlp|grep 80
        setenforce 0
        systemctl stop firewalld.service
