Ubuntu16.04搭建php5.6Web服务器环境

Ubuntu 16.04默认安装php7.0环境，但是php7目前对某些旧系统的兼容性并不是很好，如果自行安装php5需要清除php7的已安装包，否则会报错。

移除默认及已安装的PHP包

				?

添加FTP

				?

									useradd -d /var/www/tianya -s /sbin/nologin myftp

									passwd myftp

									chmod 777 -R /var/www/tianya

									usermod -s /sbin/nologin myftp

									vim /etc/vsftpd.conf

									vim /etc/vsftpd.chroot_list

									service vsftpd restart

									service vsftpd status

									# Example config file /etc/vsftpd.conf

									#

									# The default compiled in settings are fairly paranoid. This sample file

									# loosens things up a bit, to make the ftp daemon more usable.

									# Please see vsftpd.conf.5 for all compiled in defaults.

									#

									# READ THIS: This example file is NOT an exhaustive list of vsftpd options.

									# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's

									# capabilities.

									#

									#

									# Run standalone? vsftpd can run either from an inetd or as a standalone

									# daemon started from an initscript.

									#userlist_enable=YES

									#userlist_deny=NO

									#userlist_file=/etc/vsftpd.user_list

									listen=YES

									#

									# Run standalone with IPv6?

									# Like the listen parameter, except vsftpd will listen on an IPv6 socket

									# instead of an IPv4 one. This parameter and the listen parameter are mutually

									# exclusive.

									#listen_ipv6=YES

									#

									# Allow anonymous FTP? (Disabled by default)

									anonymous_enable=NO

									#

									# Uncomment this to allow local users to log in.

									local_enable=YES

									#

									# Uncomment this to enable any form of FTP write command.

									write_enable=YES

									#

									# Default umask for local users is 077. You may wish to change this to 022,

									# if your users expect that (022 is used by most other ftpd's)

									local_umask=022

									#

									# Uncomment this to allow the anonymous FTP user to upload files. This only

									# has an effect if the above global write enable is activated. Also, you will

									# obviously need to create a directory writable by the FTP user.

									#anon_upload_enable=YES

									#

									# Uncomment this if you want the anonymous FTP user to be able to create

									# new directories.

									#anon_mkdir_write_enable=YES

									#

									# Activate directory messages - messages given to remote users when they

									# go into a certain directory.

									dirmessage_enable=YES

									#

									# If enabled, vsftpd will display directory listings with the time

									# in your local time zone. The default is to display GMT. The

									# times returned by the MDTM FTP command are also affected by this

									# option.

									use_localtime=YES

									#

									# Activate logging of uploads/downloads.

									xferlog_enable=YES

									#

									# Make sure PORT transfer connections originate from port 20 (ftp-data).

									connect_from_port_20=YES

									#

									# If you want, you can arrange for uploaded anonymous files to be owned by

									# a different user. Note! Using "root" for uploaded files is not

									# recommended!

									#chown_uploads=YES

									#chown_username=whoever

									#

									# You may override where the log file goes if you like. The default is shown

									# below.

									xferlog_file=/var/log/vsftpd.log

									#

									# If you want, you can have your log file in standard ftpd xferlog format.

									# Note that the default log file location is /var/log/xferlog in this case.

									xferlog_std_format=YES

									#

									# You may change the default value for timing out an idle session.

									#idle_session_timeout=600

									#

									# You may change the default value for timing out a data connection.

									#data_connection_timeout=120

									#

									# It is recommended that you define on your system a unique user which the

									# ftp server can use as a totally isolated and unprivileged user.

									#nopriv_user=ftpsecure

									#

									# Enable this and the server will recognise asynchronous ABOR requests. Not

									# recommended for security (the code is non-trivial). Not enabling it,

									# however, may confuse older FTP clients.

									#async_abor_enable=YES

									#

									# By default the server will pretend to allow ASCII mode but in fact ignore

									# the request. Turn on the below options to have the server actually do ASCII

									# mangling on files when in ASCII mode.

									# Beware that on some FTP servers, ASCII support allows a denial of service

									# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd

									# predicted this attack and has always been safe, reporting the size of the

									# raw file.

									# ASCII mangling is a horrible feature of the protocol.

									#ascii_upload_enable=YES

									#ascii_download_enable=YES

									#

									# You may fully customise the login banner string:

									ftpd_banner=Welcome to blah FTP service.

									#

									# You may specify a file of disallowed anonymous e-mail addresses. Apparently

									# useful for combatting certain DoS attacks.

									#deny_email_enable=YES

									# (default follows)

									#banned_email_file=/etc/vsftpd.banned_emails

									#

									# You may restrict local users to their home directories. See the FAQ for

									# the possible risks in this before using chroot_local_user or

									# chroot_list_enable below.

									#chroot_local_user=YES

									#

									# You may specify an explicit list of local users to chroot() to their home

									# directory. If chroot_local_user is YES, then this list becomes a list of

									# users to NOT chroot().

									# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that

									# the user does not have write access to the top level directory within the

									# chroot)

									chroot_local_user=YES

									chroot_list_enable=YES

									# (default follows)

									chroot_list_file=/etc/vsftpd.chroot_list

									#

									# You may activate the "-R" option to the builtin ls. This is disabled by

									# default to avoid remote users being able to cause excessive I/O on large

									# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

									# the presence of the "-R" option, so there is a strong case for enabling it.

									#ls_recurse_enable=YES

									#

									# Customization

									#

									# Some of vsftpd's settings don't fit the filesystem layout by

									# default.

									#

									# This option should be the name of a directory which is empty. Also, the

									# directory should not be writable by the ftp user. This directory is used

									# as a secure chroot() jail at times vsftpd does not require filesystem

									# access.

									secure_chroot_dir=/var/run/vsftpd/empty

									#

									# This string is the name of the PAM service vsftpd will use.

									pam_service_name=vsftpd

									#

									# This option specifies the location of the RSA certificate to use for SSL

									# encrypted connections.

									rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

									# This option specifies the location of the RSA key to use for SSL

									# encrypted connections.

									rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
