记一次在centos7上编译安装mosquitto的过程

首先把mosquitto最新源码包克隆到本地

git clone https://github.com/eclipse/mosquitto.git

或者下载压缩包

wget https://mosquitto.org/files/source/mosquitto-2.0.14.tar.gz

然后解压tar xzvf mosquitto-2.0.14.tar.gz
接着进入解压目录

cd mosquitto-2.0.14
mkdir build
cmake ..

执行到cmake ..时，提示如下

CMake Error at CMakeLists.txt:7 (cmake_minimum_required):
  CMake 3.0 or higher is required.  You are running version 2.8.12.2


-- Configuring incomplete, errors occurred!

提示cmake版本小于CMakeLists.txt定义的最小版本CMake 3.0 or higher

接下来升级cmake

wget https://github.com/Kitware/CMake/releases/download/v3.23.2/cmake-3.23.2-linux-x86_64.tar.gz
tar xzvf cmake-3.23.2-linux-x86_64.tar.gz
mv cmake-3.23.2-linux-x86_64 /opt/cmake-3.23.2
sudo yum -y remove cmake
sudo ln -s cmake-3.23.2/bin/* /usr/bin/

[root@VM-12-4-centos ~]# cmake --version
cmake version 3.23.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

然后继续之前的步骤

[root@VM-12-4-centos build]# cmake ..

CMake Error at man/CMakeLists.txt:29 (message):
  xsltproc not found: manpages cannot be built


-- Configuring incomplete, errors occurred!
See also "/root/mosquitto-2.0.14/build/CMakeFiles/CMakeOutput.log".

提示xsltproc not found，那就安装下

[root@VM-12-4-centos build]# sudo yum install -y xsltproc
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

No package xsltproc available.
Error: Nothing to do

这时候再次cmake，以发现有新的提示

[root@VM-12-4-centos build]# cmake ..
-- WITH_DLT = OFF
-- Could NOT find cJSON (missing: CJSON_INCLUDE_DIR CJSON_LIBRARY) 
-- Optional dependency cJSON not found. Some features will be disabled.
CMake Error at man/CMakeLists.txt:29 (message):
  xsltproc not found: manpages cannot be built


-- Configuring incomplete, errors occurred!
See also "/root/mosquitto-2.0.14/build/CMakeFiles/CMakeOutput.log".

看来还需要把cJSON装上

[root@VM-12-4-centos cJSON]# git clone https://github.com/DaveGamble/cJSON.git

cd cJSON/
cmake ../
make && make install

然后执行cmake ..还是提示xsltproc not found，原因是刚才的xsltproc没安装对，应该这样执行

[root@VM-12-4-centos build]# sudo yum -y install libxslt 
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager

然后查看安装版本，确认安装成功OK

[root@VM-12-4-centos build]# xsltproc --version
Using libxml 20901, libxslt 10128 and libexslt 817
xsltproc was compiled against libxml 20901, libxslt 10128 and libexslt 817
libxslt 10128 was compiled against libxml 20901
libexslt 817 was compiled against libxml 20901

最后继续cmake，果然可以了

[root@VM-12-4-centos build]# cmake ../
-- WITH_DLT = OFF
-- TRUE
-- Configuring done
-- Generating done
-- Build files have been written to: /root/mosquitto-2.0.14/build

然后编译安装我们的mosquito

然后进入build目录下的src目录可以看到编译后的二进制文件

试着让mosquitto运行起来

[root@VM-12-4-centos src]# ./mosquitto -p 8023
