Centos 7.9 服務器環(huán)境搭建

1、Linux

# 查看防火墻狀態(tài)
systemctl status firewalld

# 查看已開放端口命令
firewall-cmd --list-all

# 開放端口
firewall-cmd --zone=public --add-port=3306/tcp --permanent

# 關閉端口
firewall-cmd --zone=public --remove-port=3306/tcp --permanent

# 開放端口后需要重新加載防火墻
firewall-cmd --reload

2、寶塔面板

# 安裝命令
yum install -y wget && wget -O install.sh https://download.bt.cn/install/install_6.0.sh && sh install.sh ed8484bec

tar -zxvf jdk-8u202-linux-x64.tar.gz

# 配置環(huán)境變量
vim /etc/profile

export JAVA_HOME=/usr/env/jdk/jdk1.8.0_202
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

# 生效命令
source /etc/profile

4、MySQL

# 下載安裝包

tar -xvf mysql-8.2.0-1.el7.x86_64.rpm-bundle.tar

# 安裝
rpm -ivh mysql-community-common-8.2.0-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-libs-8.2.0-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-client-8.2.0-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-server-8.2.0-1.el7.x86_64.rpm --nodeps --force

# 查詢是否安裝成功
rpm -qa|grep mysql

# 安裝成功
[root@lavm-8iaicsw6v3 mysql]# rpm -qa|grep mysql
mysql-community-common-8.2.0-1.el7.x86_64
mysql-community-libs-8.2.0-1.el7.x86_64

8023:C 12 Jan 2024 17:32:55.904 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

# 關閉 redis
./redis-cli -p 6379
