Centos Mosh 服务器端 安装笔记

Mosh 是个好东西，能长时间保持 SSH 的连接不断掉。 今天折腾了一个韩国的 vps （ centos 6 ），可以免费试用一个月。它的源无法直接安装 mosh ，于是折腾了一下，做个笔记。

cd /usr/local/data
wget https://mosh.org/mosh-1.2.6.tar.gz
tar -zxvf mosh-1.2.6.tar.gz
cd mosh-1.2.6
./config
make
make install

中间遇到几个问题

configure: error: in `/usr/local/data/mosh-1.2.6':
configure: error: no acceptable C compiler found in $PATH

这个通过安装 gcc 解决

yum install gcc

checking for protoc... no
configure: error: cannot find protoc, the Protocol Buffers compiler

尝试

yum install -y protobuf-devel
已加载插件： fastestmirror
设置安装进程
Loading mirror speeds from cached hostfile
 * base: ftp.daumkakao.com
 * extras: ftp.daumkakao.com
 * updates: ftp.daumkakao.com
No package protobuf-devel available.

好吧

cd..
git clone https://github.com/google/protobuf.git
cd protobuf
./autogen.sh

然后提示

./autogen.sh: line 35: unzip: command not found

只好

yum -y install unzip

然后再次运行 autogen.sh

 autoreconf -f -i -Wall,no-obsolete
./autogen.sh: line 48: autoreconf: command not found

需要

yum -y install autoconf

然后还是

Can't exec "automake": 没有那个文件或目录 at /usr/bin/autoreconf line 242.
Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 242.
Can't exec "aclocal": 没有那个文件或目录 at /usr/share/autoconf/Autom4te/FileUtils.pm line 326.
autoreconf: failed to run aclocal: 没有那个文件或目录

于是

yum -y install automake autoconf

但是还

+ autoreconf -f -i -Wall,no-obsolete
configure.ac:30: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1

我晕了，继续搜索，找到解决方案

yum install -y libtool libsysfs-dev

这下./autogen.sh 不报错了，但是./configure 报如下错误

configure: error: in `/usr/local/data/protobuf':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

于是

yum -y install glibc-headers gcc-c++

然后下面三个命令就都顺利了

./configure
make
make install

回到 mosh-1.2.6 目录下./configure 遇到问题：

configure: error: Unable to find zlib.

于是

yum install zlib-devel

但是再次 configure 又有

configure: error: OpenSSL crypto library not found

yum install -y openssl-devel

不过还是又有错误

checking for protobuf... no
configure: error: Package requirements (protobuf) were not met:

No package 'protobuf' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables protobuf_CFLAGS
and protobuf_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

解决办法，重新编译 protobuf

cd ../protobuf
./configure – prefix=/usr – libdir=/usr/lib64
make clean
make && make install

然后回到 mosh-1.2.6 目录下

./configure
make && make install
