#安装java环境
下载jdk-8u202-linux-x64.rpm
地址 JAVA /technologies/javase/javase8-archive-downloads.html
一键命令
“` powershell

安装 libzmq v4.3.4
#java 环境上一步已配置
#首先安装构建zeromq的依赖工具：
yum install libtool gcc gcc-c++ make libuuid-devel autoconf automake
yum -y install git
git clone
#切换目录
cd libzmq/
#查看tag
git tag
tag只是快照,检出到本地自定义分支libzmqv4.3.4
git checkout -b libzmqv4.3.4 v4.3.4
#查看是否切换成功
git branch
#配置、构建、安装、验证：
./autogen.sh
./configure
make -j4 && sudo make install
#验证 进入目录
cd /root/libzmq/perf/
./local_lat tcp://127.0.0.1:65432 1 100
#打开另一个终端 进入目录
cd /root/libzmq/perf/
./remote_lat tcp://127.0.0.1:65432 1 100
#返回 message size: 1 [B] roundtrip count: 100 average latency: 24.860 [us] 表示成功
#安装jzmq (雷同上面)
git clone
git tag
#tag只是快照,检出到本地自定义分支jzmq3.1.0
git checkout -b jzmq3.1.0 v3.1.0
#查看branch 返回jzmq3.1.0 master
git branch
##编辑Event.cpp ，参考代码对比 替换不然make install报错
报错内容如下
