1. 分布式redis部署笔记
配置文件
master节点配置
port 7001
daemonize yes
protected-mode no
#cluster-enabled yes
dir /opt/redis/7001
#cluster-config-file nodes-7001.conf
pidfile /opt/redis/redis-7001.pid
logfile /opt/redis/redis-7001.log
appendonly yes
bind 172.16.224.169
requirepass 123456
slave-read-only no
node节点配置
# node 1
port 7002
daemonize yes
protected-mode no
#cluster-enabled yes
dir /opt/redis/7002
cluster-config-file nodes-7002.conf
pidfile /opt/redis/redis-7002.pid
logfile /opt/redis/redis-7002.log
#appendonly yes
bind 172.16.224.169
#replicaof 172.16.224.169 7001
slaveof 172.16.224.169 7001
masterauth 123456
# node 2
port 7003
daemonize yes
protected-mode no
#cluster-enabled yes
dir /opt/redis/7003
cluster-config-file nodes-7003.conf
pidfile /opt/redis/redis-7003.pid
logfile /opt/redis/redis-7003.log
appendonly yes
bind 172.16.224.169
slaveof 172.16.224.169 7001

启动和关闭脚本
#启动脚本 start.sh
./src/redis-server /opt/redis/7001/redis.conf &
./src/redis-server /opt/redis/7002/redis.conf &
./src/redis-server /opt/redis/7003/redis.conf &
#./src/redis-server /opt/redis/7004/redis.conf &
# 关闭脚本 stop.sh
echo "正在关闭redis-server..."
ps -ef | grep redis | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef |grep redis
sleep
echo "正在删除redis的nodes文件..."
for ((i=7001;i<=7004;i++))
do
rm -rf /opt/redis/${i}/nodes-${i}.conf
rm -rf /opt/redis/${i}/dump.rdb
rm -rf /opt/redis/${i}/appendonly.aof
echo "删除700${i}目录下的nodes文件"
done
2. docker相关
镜像源和启动相关
- 配置镜像位置
/etc/docker/daemon.json
具体配置如下所示
{
"log-driver": "json-file",
"log-opts": {
"max-size": "512m",
"max-file": "3"
},
"registry-mirrors": ["https://registry.docker-cn.com","https://hub.atomgit.com"]
}
目前国内镜像安全原因很多不能用,需要在网上随时寻找新的地址
2. 修改启动 systemctl daemon-realod
systemctl restart docker
拉取镜像和启动服务(以mysql为例)
- 拉取镜像
docker pull msyql:5.7
版本根据需要拉取 - 查看镜像
docker images
- 启动镜像
docker run --name mysql -p 4399:3306 -e MYSQL_ROOT_PASSWORD='yourpassword' -d mysql:5.7
- --name 指定镜像启动名称
- -p 端口映射 4399服务器端口 3306容器端口
- -d 后台启动
- 修改密码和设置所有客户端可以连接的配置(默认值指定ip连接)
# 进入容器
docker ps
# 找到对于的 id
docker exec -it [CONTAINER ID] bash
# 访问数据库
mysql -u root -p
# 输入密码
# 修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
#设置所有客户端可以访问 host 任意ip访问 也可以设置为指定ip访问 根据需求来
USE mysql;
UPDATE user SET Host = '%' WHERE User = 'root';
# 设置指定ip访问
GRANT ALL PRIVILEGES ON *.* TO 'root'@'your_ip_address' IDENTIFIED BY 'password' WITH GRANT OPTION;
# 多个ip重复执行上面这个操作 如何是连续的ip段可以用通配符 比如
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.%' IDENTIFIED BY 'password' WITH GRANT OPTION;
# 刷新
FLUSH PRIVILEGES;
# 退出mysql
exit
# 退出容器
exit
Linux 内存分析查询相关
# 查询当前目录下 文件内存占用并排序展示
du -h --max-depth=1 | sort -hr
# 全盘占用分析
df -h
