1、下載地址

https://openssl-library.org/source/old/1.0.2/index.html

2、拷貝源碼到開發(fā)環(huán)境/home/elf/work目錄下解壓

elf@ubuntu:~/work$ tar zxvf openssl-1.0.2g.tar.gz

elf@ubuntu:~/work$ cd openssl-1.0.2g/

3、創(chuàng)建install文件夾用來存放編譯安裝后的庫

elf@ubuntu:~/work/openssl-1.0.2g$ mkdir install

4、生成Makefile

elf@ubuntu:~/work/openssl-1.0.2g$ ./config no-asm shared --prefix=$(pwd)/install

5、修改Makefile

注釋掉第62行；第63行去掉“-m64”

注釋掉第180行

6、執(zhí)行環(huán)境變量

elf@ubuntu:~/work/openssl-1.0.2g$ . /opt/fsl-imx-x11/4.1.15-2.0.0/environment-setup-cortexa7hf-neon-poky-linux-gnueabi

7、編譯

elf@ubuntu:~/work/openssl-1.0.2g$ make

8、安裝

elf@ubuntu:~/work/openssl-1.0.2g$ make install

9、查看安裝目錄下的文件并打包

elf@ubuntu:~/work/openssl-1.0.2g$ cd install/??

elf@ubuntu:~/work/openssl-1.0.2g/install$ ls??

bin? include? lib? ssl??

elf@ubuntu:~/work/openssl-1.0.2g/install$ tar cvjf openssl.tar.bz2 *

elf@ubuntu:~/work/mosquitto-1.5.1$ tar zxvf mosquitto-1.5.1.tar.gz

elf@ubuntu:~/work/mosquitto-1.5.1$ cd mosquitto-1.5.1/

3、創(chuàng)建install文件夾用來存放編譯安裝后的庫

elf@ubuntu:~/work/mosquitto-1.5.1$ mkdir install

4、執(zhí)行環(huán)境變量

elf@ubuntu:~/work/mosquitto-1.5.1$ . /opt/fsl-imx-x11/4.1.15-2.0.0/environment-setup-cortexa7hf-neon-poky-linux-gnueabi

5、編譯

elf@ubuntu:~/work/mosquitto-1.5.1$ make WITH_SRV=no CFLAGS="-I /home/elf/work/openssl-1.0.2g/install/include -I /home/elf/work/openssl-1.0.2g/install/lib -I /home/elf/work/openssl-1.0.2g/install/include/openssl -I /home/elf/work/libuuid-1.0.3/install/include -I /home/elf/work/libuuid-1.0.3/install/lib" LDFLAGS="-L /home/elf/work/openssl-1.0.2g/install/lib -L /home/elf/work/libuuid-1.0.3/install/lib -lssl -lcrypto -luuid" CROSS_COMPILE=" "

6、安裝

elf@ubuntu:~/work/mosquitto-1.5.1$ make DESTDIR=$(pwd)/install install

7、查看安裝目錄下的文件

elf@ubuntu:~/work/mosquitto-1.5.1$ cd install??

elf@ubuntu:~/work/mosquitto-1.5.1/install$ ls??

etc? usr??

elf@ubuntu:~/work/mosquitto-1.5.1/install$ tar cvjf mosquitto.tar.bz2 *

root@ELF1:~# cp /run/media/sda1/libuuid.tar.bz2 /??

root@ELF1:~# cp /run/media/sda1/openssl.tar.bz2 /??

root@ELF1:~# cp /run/media/sda1/mosquitto.tar.bz2 /??

root@ELF1:~# cd /??

root@ELF1:/# tar mxvf libuuid.tar.bz2??

root@ELF1:/# tar mxvf openssl.tar.bz2??

root@ELF1:/# tar mxvf mosquitto.tar.bz2

將/usr/local/lib、/usr/local/bin、/usr/local/sbin文件夾下所有文件復制到根目錄/lib文件夾下。

root@ELF1:/# cd usr/local??

root@ELF1:/usr/local# cp -rf ./lib/* /lib??

root@ELF1:/usr/local# cp -rf ./bin/* /bin??

root@ELF1:/usr/local# cp -rf ./sbin/* /bin

將/etc/mosquitto/文件夾下mosquitto.conf.example文件復制到根目錄/etc下并重命名為mosquitto.conf。

root@ELF1:/usr/local# cd /etc/mosquitto/??

root@ELF1:/etc/mosquitto# cp mosquitto.conf.example /etc/mosquitto.conf

修改/etc/mosquitto.conf文件，在第40行下添加user root。

root@ELF1:~# mosquitto -d -c /etc/mosquitto.conf

3、一端訂閱test主題

root@ELF1:~# mosquitto_sub -t test

4、一端發(fā)布test主題

root@ELF1:~# mosquitto_pub -t test -m "hello world"

可以看到訂閱端接收到發(fā)布端的“hello world”消息，測試成功。
