Write one bash script which both interactive with local bash shell and remote host ssh shell, for the purpose of deployment.

Because GFW from china, this project only updated on https://gitlab.com/zw963/deployment_bash

Use deployment_bash deploy a app to remote VPS.

Following is a example will explain what we did and what you want.

The purpose of this script is to deploy a app located in github, which deploy a lightweight SOCKS5 forward proxy to Ubuntu or CentOS.

original deploy code is here.

#!/bin/sh

# download this code, and eval.
self="$(curl https://raw.githubusercontent.com/zw963/deployment_bash/v0.2.2/deploy_start.sh)" && eval "$self"

# target is necessory, for use internal.
# any environemnt variable expect availabe in remote VPS deployment process
# need declar with export, e.g. `export abc=100`, only `abc=100`, abc not available remote.
export target=$1

# copy command copy a local file to remote, if VPS target directory not exist, will created automatically.
# copy support rsync options, e.g.
# copy ss-server/config.json /etc/shadowsocks/config.json -u
# will override remote file only local is newer.

copy ss-server/config.json /etc/shadowsocks/config.json


# this line is necessory, after this line, will execute in remote ssh shell.
deploy_start

# # Following can be any valid bash code which will be execute on remote VPS ssh shell.

# replace_string 'origin' 'new' file
# more function available, see source code.
replace_string 'mypassword' "你的密码" /etc/shadowsocks/config.json
