docker 安装

sudo yum remove docker*
sudo yum install -y yum-utils

#配置docker的yum地址
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo


#安装指定版本
sudo yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6

#    启动&开机启动docker
systemctl enable docker --now

# docker加速配置
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'

mysql

mkdir -p /mydata/mysql/log
mkdir -p /mydata/mysql/data
mkdir -p /mydata/mysql/conf
vim /mydata/mysql/conf/my.cnf
my.cnf配置文件内容如下：
[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4
[mysqld]
init_connect='SET collation_connection = utf8mb4_unicode_ci'
init_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
skip-character-set-client-handshake
skip-name-resolve
lower_case_table_names=1
mysql启动命令如下：
docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql/conf.d \
-e MYSQL_ROOT_PASSWORD=123456 \
--restart=always \
-d mysql:5.7

redis

#创建配置文件
## 1、准备redis配置文件内容
mkdir -p /mydata/redis/conf && vim /mydata/redis/conf/redis.conf
mkdir -p /mydata/redis/data

##配置示例 redis.conf内容如下：
appendonly yes
port 6379
bind 0.0.0.0


#docker启动redis
docker run -d -p 6379:6379 --restart=always \
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf \
-v  /mydata/redis/data:/data \
 --name redis-01 redis:6.2.5 \
 redis-server /etc/redis/redis.conf

nacos单机和带数据库部署

mkdir -p /mydata/nacos/logs/
mkdir -p /mydata/nacos/init.d/ 
vim /mydata/nacos/init.d/custom.properties

ElasticSearch部署

# 创建数据目录
mkdir -p /mydata/es-01 && chmod 777 -R /mydata/es-01

# 容器启动
docker run --restart=always -d -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
