# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

安装gcc

yum install -y gcc

安装go

• The Go compilers support the following instruction sets

The Go compilers support the following instruction sets:

amd64, 386
    The x86 instruction set, 64- and 32-bit.
arm64, arm
    The ARM instruction set, 64-bit (AArch64) and 32-bit.
mips64, mips64le, mips, mipsle
    The MIPS instruction set, big- and little-endian, 64- and 32-bit.
ppc64, ppc64le
    The 64-bit PowerPC instruction set, big- and little-endian.
riscv64
    The 64-bit RISC-V instruction set.
s390x
    The IBM z/Architecture.
wasm
    WebAssembly.

Be careful to double-check that the version of golang is new enough (i.e. go version), as of January 2022 version 1.16.x or higher is required. The current minimum required version can always be found in the go.mod file.

wget https://go.dev/dl/go1.18.4.linux-amd64.tar.gz
# wget https://studygolang.com/dl/golang/go1.18.4.linux-amd64.tar.gz
tar -C /usr/local -xvzf go1.18.4.linux-amd64.tar.gz

cat /etc/profile
export GO_HOME=/usr/local/go
export PATH=$GO_HOME/bin:$PATH

源码安装Podman

wget https://github.com/containers/podman/archive/refs/tags/v4.1.1.tar.gz
mv v4.1.1.tar.gz podman-v4.1.1.tar.gz
tar -C /usr/local -xvzf podman-v4.1.1.tar.gz
cd podman-4.1.1
make BUILDTAGS=""
sudo make install PREFIX=/usr

• This system is not registered with an entitlement server. You can use subscription-manager to register.

修改/etc/yum/pluginconf.d/subscription-manager.conf的enabled为0，也可以直接使用~~sed -i s/1/0/g /etc/yum/pluginconf.d/subscription-manager.conf~~替换。

cat /etc/yum/pluginconf.d/subscription-manager.conf

[main]

源码安装Redis

安装命令

wget https://github.com/redis/redis/archive/7.0.4.tar.gz
mv 7.0.4.tar.gz redis-v7.0.4.tar.gz
tar -xvzf redis-v7.0.4.tar.gz -C /usr/local/
ln -s redis-7.0.4/ redis
cd redis
make
make install

配置集群

redis.conf

port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
daemonize yes
protected-mode no

获取本机IP

ip a s
ip a s  ens32
ip a s  ens32 | sed -n '3p'
ip a s  ens32 | sed -n '3p' | sed -r 's#^.*net (.*)/24.*#\1#g'
ip a s  ens32 | sed -rn '3s#^.*net (.*)/24.*#\1#gp'

替换IP（将Redis的87行替换为bind $ip的值）

ip=$(ip a s  ens32 | sed -rn '3s#^.*net (.*)/24.*#\1#gp')
sed -i "87cbind $ip" redis.conf | grep bind
sed -i "534cmasterauth redis-masterauth-pwd" redis.conf
sed -i "1036crequirepass redis-cluster-pwd" redis.conf | grep requirepass

启动redis服务

redis-server ./redis.conf

停止redis服务

redis-cli shutdown

kill `pidof redis-server`
ps -ef | grep redis

/usr/local/bin/redis-cli -h 192.168.1.29 -a redis-cluster-pwd shutdown

启动集群

redis-cli --cluster create -a redis-cluster-pwd 192.168.1.19:6379 192.168.1.21:6379 \
192.168.1.23:6379 192.168.1.25:6379 192.168.1.27:6379 192.168.1.29:6379 \
