brew install proxychains-ng

创建配置文件

~/.proxychains/proxychains.conf

# proxychains.conf  VER 4.x
#
# HTTP, SOCKS4a, SOCKS5 tunneling proxifier with DNS.


# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
#dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#round_robin_chain
#
# Round Robin - Each connection will be done via chained proxies
# of chain_len length
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped).
# the start of the current proxy chain is the proxy after the last
# proxy in the previously invoked proxy chain.
# if the end of the proxy chain is reached while looking for proxies
# start at the beginning again.
# otherwise EINTR is returned to the app
# These semantics are not guaranteed in a multithreaded environment.
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see  chain_len) from the list.
# this option is good to test your IDS :)

# Make sense only if random_chain or round_robin_chain
#chain_len = 2

# Quiet mode (no output from library)
#quiet_mode

# Proxy DNS requests - no leak for DNS data
proxy_dns 

# set the class A subnet number to use for the internal remote DNS mapping
# we use the reserved 224.x.x.x range by default,
# if the proxified app does a DNS request, we will return an IP from that range.
# on further accesses to this ip we will send the saved DNS name to the proxy.
# in case some control-freak app checks the returned ip, and denies to 
# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
# of course you should make sure that the proxified app does not need
# *real* access to this subnet. 
# i.e. dont use the same subnet then in the localnet section
#remote_dns_subnet 127 
#remote_dns_subnet 10
remote_dns_subnet 224

# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000

### Examples for localnet exclusion
## localnet ranges will *not* use a proxy to connect.
## Exclude connections to 192.168.1.0/24 with port 80
# localnet 192.168.1.0:80/255.255.255.0

## Exclude connections to 192.168.100.0/24
# localnet 192.168.100.0/255.255.255.0

## Exclude connections to ANYwhere with port 80
# localnet 0.0.0.0:80/0.0.0.0

## RFC5735 Loopback address range
## if you enable this, you have to make sure remote_dns_subnet is not 127
## you'll need to enable it if you want to use an application that 
## connects to localhost.
# localnet 127.0.0.0/255.0.0.0

## RFC1918 Private Address Ranges
# localnet 10.0.0.0/255.0.0.0
# localnet 172.16.0.0/255.240.0.0
# localnet 192.168.0.0/255.255.0.0

# ProxyList format
#       type  ip  port [user pass]
#       (values separated by 'tab' or 'blank')
#
#       only numeric ipv4 addresses are valid
#
#        Examples:
#
# 	     socks5	192.168.67.78	1080	lamer	secret
#	     http	192.168.89.3	8080	justu	hidden
#	     socks4	192.168.1.49	1080
#	     http	192.168.39.93	8080	
#		
#        proxy types: http, socks4, socks5
#        ( auth types supported: "basic"-http  "user/pass"-socks )

[ProxyList]
# add proxy here ...

socks5  127.0.0.1 1086
#http   127.0.0.1 1087

测试

proxychains4 curl cip.cc

第二种方法

在~/.bash_profile中添加如下内容

http='http://127.0.0.1:1087'
socks5='socks5://127.0.0.1:1086'

function noproxy
{
    unset http_proxy HTTP_PROXY https_proxy HTTPS_PROXY all_proxy ALL_PROXY
    echo "clear proxy done"
}

function proxy
{
    http_proxy=$socks5
    HTTP_PROXY=$http_proxy
    https_proxy=$http_proxy
    HTTPS_PROXY=$https_proxy
    all_proxy=$http_proxy
    ALL_PROXY=$http_proxy
    echo "current proxy is ${http_proxy}"
    export http_proxy HTTP_PROXY https_proxy HTTPS_PROXY all_proxy ALL_PROXY
}

测试

~ source .bash_profile
~ proxy
current proxy is socks5://127.0.0.1:1086
~ curl cip.cc
~ noproxy
clear proxy done
