飞凌嵌入式系统安装Java环境

文章目录1.安装JDK2.mysql注意事项3.redis注意事项4.nginx注意事项5.开机自启1.安装JDK使用tar -zxvf解压不支持↓用zip来解压↓whichgzipgzip-djdk-15.0.2_linux-aarch64_bin.tar.gztar-xvfjdk-15.0.2_linux-aarch64_bin.tar2.mysql注意事项mysql安装也一样但是因为没有groupadd命令不能执行groupadd mysql和useradd -r -g mysql -s /bin/false mysql执行以下命令注意要先检查下UID 和 GID是否存在↓cat/etc/groupechomysql:x:20:/etc/groupcat/etc/passwdechomysql:x:20:20:MySQL user:/nonexistent:/bin/false/etc/passwdchown-Rmysql:mysql /userdata/local/mysql注意要下载或从其它arm架构系统获取这两个文件放入/usr/lib目录再执行./mysqld --initialize --console因为是精简的系统没有libaio文件执行初始化会报错./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory↓启动服务↓/userdata/local/mysql/support-files/mysql.server startchmod-R777你的mysql目录同样也要复制libtinfo.so到/usr/lib目录再执行./mysql -u root -p否则会报错↓别忘了my.cnf配置文件↓完成后执行systemctl enable mysqld也不行的Buildroot 默认没有 systemd↓执行vi etc/my.cnf修改配置↓[mysqld]# 设置3306端口port3306# 设置mysql的安装目录basedir/userdata/local/mysql# 设置mysql数据库的数据的存放目录datadir/userdata/local/mysql/mysqldb# 允许最大连接数max_connections10000# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统max_connect_errors10# 服务端使用的字符集默认为utf8mb4character-set-serverutf8mb4# 创建新表时将使用的默认存储引擎default-storage-engineINNODB#

设置mysql客户端连接服务端时默认使用的端口port3306default-character-setutf8执行vi /etc/init.d/mysql进行配置↓#!/bin/shMYSQLD/userdata/local/mysql/bin/mysqldMYSQL_CONF/etc/my.cnfMYSQL_PID/var/run/mysqld.pidauthentication_policymysql_native_passwordcase$1instart)echoStarting

/etc/init.d/mysql#如果目录不存在则先新建此目录mkdir-p/etc/rc3.dln-s/etc/init.d/mysql /etc/rc3.d/S98mysql /etc/init.d/mysql start /etc/init.d/mysql stop /etc/init.d/mysql restart3.redis注意事项因为嵌入式系统没有GCC安装redis会报错。可以在其它系统交叉编译后拷贝过来。我这里采用的是在一台centos8虚拟机编译。进入官网搜索GCC查看相关文章↓下载地址https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/如图解压gcc和redis压缩包到当前目录分别命名为gcc和reids↓#设置 PATH 环境变量exportPATH$PATH:/home/temp/gcc/bin# 验证 GCC 是否可用正常输出aarch64-linux-gnu-gcc (Linaro GCC 7.5-2019.12) 7.5.0aarch64-linux-gnu-gcc--versioncd/home/temp/redis#单线程编译以减少内存占用make-j1#安装到cross-redis目录makePREFIX/home/temp/cross-redisinstall#检查生成的二进制文件是否为 AArch64 架构正常输出/home/temp/cross-redis/bin/redis-server: ELF 64-bit LSB executable, ARM aarch64, ...file/home/temp/cross-redis/bin/redis-server编译好后传输至飞凌↓不要忘了配置文件执行vi etc/redis.conf修改↓daemonizeyesdir/userdata/redis-data logfile /userdata/redis-data/redis.log保存后执行vi /etc/init.d/redis加入以下配置↓#!/bin/shREDIS_SERVER/userdata/local/redis/bin/redis-serverREDIS_CONF/etc/redis.confREDIS_PID/var/run/redis.pidcase$1instart)echoStarting Redis...$REDIS_SERVER$REDIS_CONF;;stop)echoStopping

/etc/init.d/redisln-s/etc/init.d/redis /etc/rc3.d/S99redis /etc/init.d/redis start /etc/init.d/redis stop /etc/init.d/redis restartpsaux|grepredis-server4.nginx注意事项接下来还是在centos编译nginx。nginx需要zlib和pcre支持先下载压缩包解压。我这里不仅有源码还有带-aarch64的目录代表是已经独立 编译过的我采用的是动态编译↓# 设置过临时变量的可以不用设置但是如果是新启用会话得重新设置包括export PATH$PATH:/home/temp/gcc/binexportTOOLCHAIN/home/temp/gccexportPATH$TOOLCHAIN/bin:$PATHexportCC$TOOLCHAIN/bin/aarch64-linux-gnu-gccexportLD$TOOLCHAIN/bin/aarch64-linux-gnu-ldexportAR$TOOLCHAIN/bin/aarch64-linux-gnu-arexportAS$TOOLCHAIN/bin/aarch64-linux-gnu-asexportCXXaarch64-linux-gnu-g

--with-zlib/home/temp/zlibmake-j1makeinstall这时候编译会出错↓编译完后执行/home/temp/nginx-aarch64/sbin/nginx -v验证↓如果是静态编译先独立编译zlib和pcre↓#编译zlibpcre照着来重复遍就行注意目录cdzlib/ ./configure--prefix/home/temp/zlib-aarch64make-j1makeinstall然后再编译nginx↓exportLD/home/temp/gcc/bin/aarch64-linux-gnu-ldexportAR/home/temp/gcc/bin/aarch64-linux-gnu-arexportAS/home/temp/gcc/bin/aarch64-linux-gnu-asexportCXXaarch64-linux-gnu-gexportCFLAGS-O2

/etc/rc.local如果编译时的路径与现在的安装路径不致执行mkdir-p/home/makeln-s/userdata/local/nginx-aarch64 /home/make/nginx-aarch64测试/etc/init.d/nginx start /etc/init.d/nginx stop /etc/init.d/nginx restart /etc/init.d/nginx reload5.开机自启最后的rc.local配置如下↓#!/bin/sh -e# 启动 redis/etc/init.d/redis start# 启动 mysql/etc/init.d/mysql start# 启动 nginx/etc/init.d/nginx startexit0设置了rc.local并不一定会开机自启。使用cat /etc/inittab查看 /etc/inittab 是否调用了 rc.local↓你应该看到类似这一行↓::sysinit:/etc/rc.local如果没有你需要手动添加一定要放在启动程序的最后一个↓如果像这样随便放一个地方会出现问题因为系统环境还没初始化好↓如果想查看日志可以这样写↓#!/bin/sh -eechorc.local begin/tmp/rc.local.log# 启动 redis/etc/init.d/redis start/tmp/rc.local.log21# 启动 mysql/etc/init.d/mysql start/tmp/rc.local.log21# 启动 nginx/etc/init.d/nginx start/tmp/rc.local.log21exit0
