centos安装cowboy过程

Posted 2020-11-05 莫行

在centos机器上安装erlang：

    yum install erlang -y

接着把之前在ubuntu上的cowboy工程拷贝到centos机器上，进入到工程目录，输入：

    make run

提示Error:“Please upgrade to Make 4 or later”，于是google了make的升级过程，如下：

    wget http://ftp.gnu.org/gnu/make/make-4.2.tar.gz

    tar -xzvf make-4.2.tar.gz

    cd make-4.2

    ./configure

    make && make run #会将make安装到/usr/local/bin目录下

    which make #查看当前的make执行位置，为/usr/bin/make

    cd /usr/bin/make

    mv make makebak

    ln -s /usr/local/bin/make ./make #建立符号链接指向/usr/local/bin/make

再次进入工程目录make run，提示Error:

    “Error loading module relx: use of opcode 153; this simulator supports only up to 152”

在stack-overflow上搜索得到解答：

    “The error use of opcode 153; this simulator supports only up to 152 means that you have a relx.beam file that was compiled with Erlang/OTP R15 or later, but you‘re trying to run it in R14 or earlier. Upgrade to a newer Erlang version, or if you already have a newer version, figure out where the old Erlang is hiding and remove it.”

重新安装高版本的erlang:

    yum install -y which wget perl openssl-devel make automake autoconf ncurses-devel gcc

    wget http://erlang.org/download/otp_src_20.2.tar.gz

    tar -zxvf otp_src_20.2.tar.gz

    cd otp_src_20.2

    ./otp_build autoconf

    ./configure && make && make install
