OTP 23 in CentOS7

啟動 docket image for testing

#docker run -d --sysctl net.ipv6.conf.all.disable_ipv6=1 --name test -p 20022:22 centos7ssh /usr/sbin/sshd -D
#docker run -d --name test -p 20022:22 centos7ssh /usr/sbin/sshd -D
docker run -d -p 10022:22 -e "container=docker" --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup --name test centosssh /usr/sbin/init

docker exec -it test /bin/bash

Preparation

安裝 libraries

# wxWidget library
yum -y install gtk2-devel binutils-devel

yum -y install gcc gcc-c++ glibc-devel make ncurses-devel openssl-devel autoconf git bzip2

# 先裝 OpenGL 相關函式庫，FOP是用來產生文件
yum -y install mesa* fop unixODBC*

download OTP, wxWidget source

wget https://erlang.org/download/otp_src_23.3.tar.gz
#wget https://erlang.org/download/otp_src_24.0.tar.gz

wget https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.5/wxWidgets-3.1.5.tar.bz2

wxWidgets

yum remove wx*

設定 lib path，新增檔案並填寫一行 /usr/local/lib

vi /etc/ld.so.conf.d/locallib.conf
# 內容為
/usr/local/lib

ldconfig

note: 後面有因為一些狀況，重新編譯 wxWidgets

tar -jxvf wxWidgets-3.1.5.tar.bz2
cd wxWidgets-3.1.5
./configure --with-gtk --with-opengl --enable-debug --enable-unicode --enable-compat28
make
make install


ln -s /usr/local/include/wx-3.1/ /usr/local/include/wx

cd ..

openjdk

# 1.8
#yum -y install java-1.8.0-openjdk  java-1.8.0-openjdk-devel

# 11
yum -y install java-11-openjdk java-11-openjdk-devel

以 alternatives 調整執行檔的目標

alternatives --config java
alternatives --config javac
alternatives --config javadoc
alternatives --config javah
alternatives --config javap

設定環境變數

vi /etc/profile

export JAVA_HOME=/usr/lib/jvm/java-openjdk
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin


source /etc/profile

erlang OTP 23

如果不指定 --libdir 會造成 /usr/lib/erlang/lib 裡面的 library 混雜了不同版本的 erlang library，使用時，有可能會發生 ebeam 版本檢查錯誤，因為使用 otp 23 的 erl，但是引用了 otp 24 的 library

tar zxvf otp_src_23.3.tar.gz
cd otp_src_23.3

# 先將 /usr/lib/erlang 目錄，修改為原本的 erlang otp 的獨立資料夾
mv /usr/lib/erlang /usr/lib/erlang20.3

# 增加 --libdir，會讓 erlang 23 安裝到 /usr/lib/erlang23/erlang 這個路徑
#./configure --prefix=/usr --libdir=/usr/lib/erlang23
./configure --prefix=/usr
make
make install
cd ..

erlang OTP 24

tar zxvf otp_src_24.0.tar.gz
cd otp_src_24.0

# 先將 /usr/lib/erlang 目錄，修改為原本的 erlang otp 的獨立資料夾
mv /usr/lib/erlang /usr/lib/erlang23.3

# 增加 --libdir，會讓 erlang 24 安裝到 /usr/lib/erlang24/erlang 這個路徑
#./configure --prefix=/usr --libdir=/usr/lib/erlang24
./configure --prefix=/usr
make
make install
cd ..

編譯 OTP 24 會出現 error

wx             : wxWidgets was not compiled with --enable-webview or wxWebView developer package is not installed, wxWebView will NOT be available
erts           :
                 JIT disabled due to lack of compiler with C++17 support

Patch1: 要重編譯 wxWidget，且要先安裝 webkitgtk

nux webkitgtk

# 安裝 nux repo
yum -y install epel-release
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

yum -y install webkitgtk webkitgtk-devel

# --enable-webview
cd wxWidgets-3.1.5
./configure --with-gtk --with-opengl --enable-debug --enable-unicode --enable-compat28 --enable-webview

make
make install
cd ..

Patch2: JIT 支援問題，要安裝 GCC 7.3 支援 C++17

可不管 JIT disabled due to lack of compiler with C++17 support warning，直接 make

Centos 7 GCC 7.3 compiler installation method and C++17 standard test example

How to Install GCC Compiler on CentOS 7

CentOS 7 預設為 gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

Software Collections SCL 提供安裝多個 gcc 版本的方法

yum -y install centos-release-scl

目前有兩個 Developer Toolset collections

• Developer Toolset 7
• Developer Toolset 6

# 安裝
yum -y install devtoolset-7

# 啟動 devtoolset-7
scl enable devtoolset-7 bash

# version check
gcc --version
# gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5)

RabbitMQ

如果要安裝 RabbitMQ，要先參考

Signatures

RabbitMQ Erlang Version Requirements 確認 Erlang 跟 RabbitMQ 的版本匹配

Downloading and Installing RabbitMQ

yum install socat

rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.19/rabbitmq-server-3.8.19-1.el7.noarch.rpm
rpm --nodeps -Uvh rabbitmq-server-3.8.19-1.el7.noarch.rpm

rabbitmq-plugins enable rabbitmq_management
http://localhost:15672/

#新增一個帳號

rabbitmqctl add_user admin password
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator

rabbitmqctl delete_user guest
rabbitmqctl list_users

systemctl start rabbitmq-server
systemctl status rabbitmq-server
systemctl enable rabbitmq-server
