jdk安装验证系统是否自带jdk环境

pm -qa|grep java rpm -qa|grep jdk rpm -qa|grep gcj

卸载opnejdk

yum -y remove copy-jdk-configs-3.7-1.el8.noarch

验证

java -version

解压

tar xf jdk-8u241-linux-x64.tar.gz

配置环境变量

export JAVA_HOME=/usr/soft/jdk/jdk1.8.0_241 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin

配置文件生效

source /etc/profile

mave安装解压

tar xf apache-maven-3.8.1-bin.tar.gz

配置环境变量

export MAVEN_HOME=/usr/soft/maven/apache-maven-3.8.1 export PATH=$MAVEN_HOME/bin:$PATH

配置文件生效

msyql安装验证系统是否自带mysql环境

rpm -qa | grep mysql

卸载mysql

rpm -ev mysql-libs-* --nodeps

安装mysql

rpm -ivh mysql-community-client-5.7.32-1.el7.x86_64.rpm --force --nodeps rpm -ivh mysql-community-common-5.7.32-1.el7.x86_64.rpm --force --nodeps rpm -ivh mysql-community-libs-5.7.32-1.el7.x86_64.rpm --force --nodeps rpm -ivh mysql-community-server-5.7.32-1.el7.x86_64.rpm --force --nodeps

启动mysql

service mysqld statusservice mysqld start

初始化随机密码

cat /var/log/mysqld.log | more

查看密码

grep pass /var/log/mysqld.log --color

登录修改密码

mysql -uroot -p set global validate_password_policy=LOW; set global validate_password_length=6; set password=\'abcd@1234\'; grant all privileges on *.* to \'root\'@\'%\' identified by \'abcd@1234\';

mysql命令无效安装依赖包

yum install libncurses*

设置开机启动

systemctl enable mysqld systemctl daemon-reload

打开远程访问及端口

update user set host=\'%\' where user=\'root\'; Alter user \'root\'@\'%\' identified by \'abcd@1234\'; grant all privileges on *.* to \'root\'@\'%\' with grant option; FLUSH PRIVILEGES; //查看防火墙状态 systemctl status firewalld //开启防火墙 systemctl start firewalld //设置端口 firewall-cmd --zone=public --add-port=3306/tcp --permanent //重启防火墙 firewall-cmd --reload //查询 firewall-cmd --zone=public --query-port=3306/tcp

设置忽略大小写

/etc/my.cnf lower_case_table_names=1 service mysqld restart

redis安装解压

tar xf redis-6.2.5.tar.gz

安装gcc环境

yum install gcc-c++

进入解压目录编译与安装

cd /usr/soft/redis/redis-6.2.5/make cd ./src make install

统一管理配置与常用命令

mkdir bin mkdir etc mv redis.conf ./etc/ cd ./src mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-cli redis-server /usr/soft/redis/redis-6.2.5/bin/

编辑redis.conf文件

daemonize改为yes注释bind 127.0.0.1protected-mode改为no修改requirepass默认密码

设置开机启动将以下文本加入到 /etc/rc.d/rc.local中

/usr/soft/redis/redis-6.2.5/bin/redis-server/usr/soft/redis/redis-6.2.5/etc/redis.conf

启动redis服务

cd /usr/soft/redis/redis-6.2.5/bin/ ./redis-server /usr/soft/redis/redis-6.2.5/etc/redis.conf

开放端口

//查看防火墙状态 systemctl status firewalld //开启防火墙 systemctl start firewalld //设置端口 firewall-cmd --zone=public --add-port=6379/tcp --permanent //重启防火墙 firewall-cmd --reload //查询 firewall-cmd --zone=public --query-port=6379/tcp

jenkins安装安装

rpm -ivh jenkins-2.174-1.1.noarch.rpm

配置jdk路径

/etc/init.d/jenkins /usr/soft/jdk/jdk1.8.0_241/bin/java

设置jenkins用户root权限

/etc/init.d/jenkins $JENKINS_USER="root" chown -R root:root /var/lib/jenkins chown -R root:root /var/cache/jenkins chown -R root:root /var/log/jenkins systemctl restart jenkins

查找jenkins安装目录

whereis jenkins

启动jenkins

service jenkins star

开放端口

//查看防火墙状态 systemctl status firewalld //开启防火墙 systemctl start firewalld //设置端口 firewall-cmd --zone=public --add-port=8080/tcp --permanent //重启防火墙 firewall-cmd --reload //查询 firewall-cmd --zone=public --query-port=8080/tcp
