背景
这里实验用的华为云鲲鹏服务器配置如下：
Huawei Kunpeng 920 2.6GHz
4vCPUs | 8GB
openEuler 20.03 64bit with ARM
连接机器后，先查看系统相关信息，注意这里是 aarch64 的，后续软件包也需要是 aarch64 版本的。
# 查看系统内核信息
[root@ecs-kunpeng-0005 ~]# uname -a
Linux ecs-kunpeng-0005 4.19.90-2003.4.0.0036.oe1.aarch64 #1 SMP Mon Mar 23 19:06:43 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux
# 查看系统版本信息
[root@ecs-kunpeng-0005 ~]# cat /etc/os-release

安装Redis
- 下载安装
- 下载：
https://redis.io/download - 上传：
redis-6.2.3.tar.gz到服务器
# 解压
[root@ecs-kunpeng-0006 local]# tar -xvf redis-6.2.3.tar.gz
[root@ecs-kunpeng-0006 local]# mv redis-6.2.3 redis
[root@ecs-kunpeng-0006 local]# cd redis
# 编译
[root@ecs-kunpeng-0006 redis]# make
# 安装
[root@ecs-kunpeng-0006 redis]# make PREFIX=/usr/local/redis install
# 指定配置文件自动，这里配置了端口号为6380
[root@ecs-kunpeng-0006 redis]# bin/redis-server ./redis.conf

上面 Redis Server 启动后又停止了，并且报了一个警告： Your kernel has a bug that could lead to data corruption during background save. Please upgrade to the latest stable kernel. 并且，给了解决的建议，即在 redis.conf 中取消这最后一条注释： ignore-warnings ARM64-COW-BUG 。
# 编辑vi redis.conf ，取消最后一行相关注释
[root@ecs-kunpeng-0006 redis]# vi redis.conf
ignore-warnings ARM64-COW-BUG
# 尝试启动
[root@ecs-kunpeng-0006 redis]# bin/redis-server ./redis.conf

启动成功๑乛◡乛๑
- 远程访问
# 注释第75行的bind，同时将94行的protected-mode由yes改为no
[root@ecs-kunpeng-0006 redis]# vi redis.conf
75 #bind 127.0.0.1 -::1
94 protected-mode no
- 后台启动
# 将257行的daemonize由no改为yes
[root@ecs-kunpeng-0006 redis]# vi redis.conf
257 daemonize yes
- 开启认证
# 将901行的requirepass开启，改为自己的密码
[root@ecs-kunpeng-0006 redis]# vi redis.conf
901 requirepass your-guess
- 停止服务
# 无密码停止服务
[root@ecs-kunpeng-0006 redis]# bin/redis-cli -h 127.0.0.1 -p 6380 shutdown
# 带密码停止服务
[root@ecs-kunpeng-0006 redis]# bin/redis-cli -a 密码 -h 127.0.0.1 -p 6380 shutdown
- 配置日志
以后台方式启动后，发现 Redis 的日志完全没了。。所以需要配置下日志路径。
[root@ecs-kunpeng-0006 redis]# vi redis.conf
# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null
logfile ""
改为：
logfile "/usr/local/redis/log/redis.log"
# 需要手动创建目录，redis.log文件在下次启动时则会自动创建
[root@ecs-kunpeng-0006 redis]# mkdir log
# 启动即可
[root@ecs-kunpeng-0006 redis]# bin/redis-server ./redis.conf
Note: Redis 默认端口为 6379 ，我这里改了端口为 6380 。
- 配置Redis服务开机自启
[root@localhost redis]# vi /etc/systemd/system/redis.service
[Unit]
Description=redis-server
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/redis.conf
PrivateTmp=true
[Install]
WantedBy=multi-user.target
- 验证开机自启
[root@localhost redis]# systemctl list-unit-files | grep redis
redis.service disabled
[root@localhost redis]# systemctl enable redis
Created symlink /etc/systemd/system/multi-user.target.wants/redis.service → /etc/systemd/system/redis.service.
[root@localhost redis]# systemctl list-unit-files | grep redis
redis.service enabled
- 常用命令
systemctl start redis systemctl enable redis systemctl status redis systemctl stop redis
安装Zookeeper
# 下载
[root@ecs-kunpeng-0001 local]# wget https://mirrors.bfsu.edu.cn/apache/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
# 解压
[root@ecs-kunpeng-0001 local]# tar -xvf apache-zookeeper-3.6.3-bin.tar.gz
[root@ecs-kunpeng-0001 local]# mv apache-zookeeper-3.6.3-bin zookeeper
[root@ecs-kunpeng-0001 zookeeper]# cp conf/zoo_sample.cfg conf/zoo.cfg
# 配置数据与日志目录，zk在第一次启动时会自动创建
[root@ecs-kunpeng-0001 zookeeper]# vi conf/zoo.cfg
dataDir=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/log
# 尝试启动
[root@ecs-kunpeng-0001 zookeeper]# bin/zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
# 查看状态
[root@ecs-kunpeng-0001 zookeeper]# bin/zkServer.sh status
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: standalone
安装Nginx
配置好源后，这里使用 yum 或者 dnf 来安装 Nginx 。
# yum安装nginx
[root@ecs-kunpeng-0001 ~]# yum install nginx
[root@ecs-kunpeng-0001 ~]# nginx -v
nginx version: nginx/1.16.1
# 配置服务
[root@ecs-kunpeng-0001 ~]# vi /etc/nginx/nginx.conf
# 加载配置
[root@ecs-kunpeng-0001 ~]# nginx -s reload
nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
在重新加载配置时有个警告：
nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
# 编辑vi /etc/nginx/nginx.conf，在http下增加配置：types_hash_bucket_size 1024;
[root@ecs-kunpeng-0001 ~]# vi /etc/nginx/nginx.conf
types_hash_bucket_size 1024
# 测试配置
[root@ecs-kunpeng-0001 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# 查看Nginx状态，active
[root@ecs-kunpeng-0001 ~]# service nginx status
