First, the system environment

#未安装etags, install with Yum

You have configured a dual-machine SSH trust. (Omit configuration process)

Second, installation ocaml-3.10.2

# tar ZXVF ocaml-3.10.2.tar.gz # cd ocaml-3.10.2# #需删除man1, or error # rm-rf/usr/local/man/man1#./configure # make Word opt# Make install

Third, installation unison-2.32.52

# tar zxvf unison-2.32.52.tar.gz# cd unison-2.32.52# make Uistyle=text threads=true static=true# CP Unison/usr/local/bin /

Iv. Testing Connectivity

# unison/ssh://192.168.1.23/-testserver

Six, unison parameter detailed (network)


-testserver

Test connectivity, and the connection to the server exits. Example:

# Unison/ssh://[email protected]/-servercmd=/usr/local/bin/unison-testserver

    If the server-side unison executable is not in the default directory, even if there is no unison command (you need to compile one to upload to the server), you need to use the-servercmd parameter to tell the server to execute Unison The command location.

    using the-testserver parameter, the successful link exits, and does not perform subsequent operations such as directory comparisons.

   -servercmd xxx

    tell unison what the server-side unison command is. See the example above.

   -auto

    Accept the default action and wait for the user to confirm that it is executed.

   -batch

    batch mode, automatic mode, accept the default action, and execute.

   -ignore xxx

    add xxx to the Ignore list

   -ignorecase [True|false|default]

    Ignore file name capitalization

   -follow xxx

    Whether to support synchronization of symbolic connections to content;

    For example, in my ~/.unison configuration file default.prf, there are

    # unison Preferences File Follow = path {unison_*} ignore = path {Wwwroot/wiki_mirror} ignore = Name {,.} *{.~ $lock} ignore = Name {a.out}

I will pre-synchronize the system files under XXX/SRC, respectively, as a symbolic link, such as unison_httpd.conf point to C:/Program files/apache/.../httpd.conf. When synchronizing, the "follow = Path {unison_*}" configuration (or parameter) will track the actual file that the symbolic link points to. If you do not have this setting, the symbolic links are not synchronized.

-immutable xxx

Constant directory, ignored when scanning

-silent

Quiet mode

-times

Synchronization modification Time

-path XXX Parameters

Synchronizes only the subdirectories and files specified by the-path parameter, not the entire directory. For example

Unison/home/username ssh://remotehost//home/username \-path shared \-path pub \-path. netscape/bookmarks.html
