如何用脚本安装部署openresty

1. 压缩吧解压到/opt下执行脚本，将安装到/usr/local/openresty
   
2. 脚本如下：

#!/bin/bash
#init dir
autoDir="/usr/local/src"
sourceDir="/opt/openresty"
openrestyTarGz="openresty-1.15.8.2.tar.gz"
opensslTarGz="openssl-1.0.1l.tar.gz"
zlibTarGz="zlib-1.2.8.tar.gz"
pcreTarGz="pcre-8.31.tar.gz"

mkdir -p /usr/local/src/{zlib,pcre,openssl,openresty}

#openresty 
cd /usr/local/
if [[ -d openresty ]]; then
echo "WARN: openresty is already installed, exit."
#return
exit
fi
#install Dependent package
#yum install -y gcc gcc-c++ pcre zlib openssl
#untar
cd ${sourceDir} 
tar zxvf ${openrestyTarGz} -C /usr/local/src/openresty --strip-component=1  
tar zxvf ${opensslTarGz} -C /usr/local/src/openssl --strip-component=1  
tar zxvf ${zlibTarGz} -C /usr/local/src/zlib --strip-component=1
tar zxvf ${pcreTarGz} -C /usr/local/src/pcre --strip-component=1
chmod -R 777 ${autoDir}
#install openresty

cd ${autoDir}/openresty
./configure --prefix=/usr/local/openresty  --with-http_stub_status_module  --with-stream --with-stream_ssl_module --with-pcre=/usr/local/src/pcre --with-openssl=/usr/local/src/openssl --with-zlib=/usr/local/src/zlib
make && make install
if [[ $? == 0 ]]; then
    cp -fv $sourceDir/openresty.service /usr/lib/systemd/system && systemctl daemon-reload
    echo "OK: openresty is installed, exit."
    else
    echo "ERROR: openresty is NOT installed, exit."
fi
