centos7.9安装java1.8.0_202\libzmq4.3.4\jzmq3.1.0环境记录

#安装java环境

下载jdk-8u202-linux-x64.rpm

地址 https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

一键命令

```powershell

rpm -ivh /root/jdk-8u202-linux-x64.rpm

wait

sed -r -i '/java|CLASSPATH|JAVA_HOME|LD_LIBRARY_PATH/ s/^/#&/' /etc/profile

echo "#set java environment

JAVA_HOME=/usr/java/jdk1.8.0_202-amd64

CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar

PATH=\$JAVA_HOME/bin:\$PATH

LD_LIBRARY_PATH=/usr/local/lib:\$LD_LIBRARY_PATH

export JAVA_HOME CLASSPATH PATH LD_LIBRARY_PATH" >> /etc/profile

echo -e "\e\033[33m jdk_rpm install ok! \e[0m"

ldconfig

source /etc/profile && java -version

```

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 https://github.com/zeromq/libzmq.git

#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 https://github.com/zeromq/jzmq.git

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 https://github.com/zeromq/jzmq/commit/eb40d6db43ce3545e623dad6cc6721a90885b5ba 替换不然make install报错

报错内容如下

```powershell

vim src/main/c++/Event.cpp

./autogen.sh

./configure

make -j4 && sudo make install
