布置Rocky java生产环境
布置Rocky java生产环境 升级gcc+Mysql + Nginx +java+maven+Docker+redis+chromium
设置静态IP、DNS地址(网络设备名称有可能不一样,这里是ifcfg-enp0s3,如使用DHCP获取动态IP,可忽略)
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
找到BOOTPROTO,并且修改(设为静态网址)
BOOTPROTO="static"
在最后添加三行内容(添加本机IP,子网掩码,网关)
IPADDR="192.168.1.10"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
:wq 保存退出
[root@localhost ~]# shutdown -r now
添加以下几个DNS地址
nameserver 192.168.1.1
nameserver 8.8.8.8
更新系统,Rocky8 换源
[root@localhost ~]# sed -e 's|^mirrorlist=|#mirrorlist=|g' \ -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.sjtug.sjtu.edu.cn/rocky|g' \ -i.bak \ /etc/yum.repos.d/Rocky-*.repo
[root@localhost ~]# yum clean all && yum makecache
[root@localhost ~]# yum update -y

升级 gcc
[root@localhost ~]# cd /usr/local/src
[root@localhost src]# tar zvxf gcc-12.1.0.tar.gz && cd gcc-12.1.0
下载依赖文件,并且刷新 (可以事先下载复制进去)

重启,查看版本,检查是否成功更新
[root@localhost ~]# shutdown -r now
[root@localhost ~]# gcc --version
[root@localhost ~]# g++ --version
设置PUTTY远程登录时,不使用密码,使用密钥文件登录(如不需要,可忽略)
服务器上创建目录
[root@localhost ~]# mkdir -p /root/.ssh
在"客户机"生成对称密钥,把客户机上的公钥复制到服务器(公钥文件:id_rsa.pub)
[root@centos ~] ssh-keygen -m PEM -t rsa -b 4096
根据提示操作,生成公钥
上传到服务器指定目录(*** 或使用软件远程复制id_rsa.pub到服务器/root/.ssh中。)
[root@centos ~] scp id_rsa.pub root@192.168.1.10/root/.ssh
查看服务器上,公钥是否已经存在
[root@localhost .ssh]# cd /root/.ssh
[root@localhost .ssh]# ll
-rw-r--r-- 1 root root 394 12月 5 09:33 id_rsa.pub
导入密钥到authorized_keys
[root@localhost .ssh]# cat id_rsa.pub >> authorized_keys
[root@localhost .ssh]# ll /root/.ssh
-rw-r--r-- 1 root root 394 12月 5 09:37 authorized_keys
-rw-r--r-- 1 root root 394 12月 5 09:33 id_rsa.pub
导入后,删除公钥文件
[root@localhost .ssh]# rm id_rsa.pub
设置目录和文件读取权限
[root@localhost .ssh]# chmod 700 /root/.ssh
[root@localhost .ssh]# chmod 600 /root/.ssh/authorized_keys
设置sshd配置文件
[root@localhost .ssh]# vim /etc/ssh/sshd_config
找到GSSAPICleanupCredentials,并且修改为以下内容
GSSAPICleanupCredentials yes
:wq 保存退出
重启sshd服务,让其生效
[root@localhost .ssh]# systemctl restart sshd
客户端设置PUTTY,进行远程登录
打开软件 PuTTYgen
点击load 选择之前客户机生成私钥文件id_rsa, 点击save private key 生成 pKey.ppk文件
打开软件 PuTTY
点击Session,在HostName(or IP address)输入服务器地址
点击Connection下的DATA,在Auto-login username中输入登录账号(当前账号为root)
点击Connection下的SSH下的Auth,点击Browse 选择之前生成 pKeyppk文件
点击Session,在Saved Sessions中,输入需要保存的Session名称,点击保存
1.7.6 设置完成后,即可以远程连接到服务器
打开软件 PuTTY
点击Session,在"Default Settings"下,找到之前已经保存的Session,双击打开连接
如果显示 Authenticating with public key "xxxxx-xxxx"时,即表未成功
设置新用户,并且使用密码和证书双重认证远程登录。同时禁止root远程登录 (如不需要,可忽略)
root登录后,修改root密码 (安全建议:密码为15位,大小字母+数字+特殊字符)
passwd
添加新用户,并且设置密码
[root@localhost ~]# adduser lixin
[root@localhost ~]# passwd lixin
创建目录,复制密钥相关文件到用户目录,并且设置权限
[root@localhost ~]# mkdir /home/lixin/.ssh -p
[root@localhost ~]# cp /root/.ssh/authorized_keys /home/vicowong/.ssh
[root@localhost ~]# chmod 700 /home/lixin/.ssh
[root@localhost ~]# chmod 600 /home/lixin/.ssh/authorized_keys
[root@localhost ~]# chownlixin:lixin /home/lixin/.ssh -R
设置防火墙,设置远程连接端口(这里是26322)
[root@localhost ~]# systemctl enable firewalld && systemctl start firewalld
[root@localhost ~]# firewall-cmd --zone=public --add-port=26322/tcp --permanent
[root@localhost ~]# firewall-cmd --reload && iptables -L --line-numbers|grep ACCEPT
安装semanage(用于设置selinux策略)
[root@localhost ~]# yum install -y policycoreutils-python selinux-policy selinux-policy-targeted
查看当前 selinux 是否启用 即 Enforcing 状态 (否则有可能设置 selinux 策略不成功)
[root@localhost ~]# getenforce
查看当前 selinux 关于远程ssh连接端口的设置
[root@localhost ~]# semanage port -l | grep ssh
ssh_port_t tcp 22
添加新端口
[root@localhost ~]# semanage port -a -t ssh_port_t -p tcp 26322
--------------------------------------------------------------------------------------------
移除端口
[root@localhost ~]# semanage port -d -t ssh_port_t -p tcp 26322
-------------------------------------------------------------------------------------------
设置sshd配置文件
[root@localhost ~]# vim /etc/ssh/sshd_config
以下三个搜索,查看是否有重复设置
#PermitRootLogin yes
#PasswordAuthentication yes
#AuthorizedKeysFile .ssh/authorized_keys
#X11Forwarding yes
添加
Port 26322
Protocol 2
ServerKeyBits 1024
PermitRootLogin no
AllowUsers vicowong
StrictModes yes
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PermitEmptyPasswords no
PasswordAuthentication yes
AuthenticationMethods publickey,password
X11Forwarding no
MaxStartups 10:30:60
:wq 保存退出
重启sshd服务,让其生效
[root@localhost ~]# systemctl restart sshd
使用新用户登录(重新打开一个新终端,原来的终端先不关,避免因设置不当导致没法连接远程)
打开软件 PuTTY,点击之前保存的Sessions,点击Load读取之前的配置
在Port框输入端口(当前账号为26322)
点击Connection下的DATA,在Auto-login username中输入登录账号(当前账号为lixin)
点击Session 点击Save。保存当前修改。
点击Open,打开终端。
设置后,必须远程将进行密码和证书双重认证。
远程登录会以lixin这个账号进行登录。安装维护需要root权限时,可以使用su实现
[root@localhost ~]# su root
安装mysql
[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql -s /sbin/nologin -M

[root@localhost src]# vim /etc/selinux/config
设置 SELINUX=disabled
[root@localhost src]# shutdown -r now
[root@localhost ~]# mkdir /data/data
[root@localhost ~]# mkdir /data/data/mysql
修改mysql配置文件
[root@localhost ~]# vim /etc/my.cnf
datadir = /data/data/mysql
user = mysql
初始化mysql
[root@localhost ~]# mysqld --initialize --console
启动mysql
[root@localhost ~]# systemctl start mysqld.service
[root@localhost ~]# systemctl status mysqld.service
[root@localhost nginx]# netstat -tlnp
防火墙添加3306端口(不远程连接数据,可忽略)
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
[root@localhost ~]# firewall-cmd --reload && iptables -L --line-numbers|grep ACCEPT
[root@localhost ~]# firewall-cmd --list-all
查看原始密码
[root@localhost ~]# cat /var/log/mysqld.log
使用原始密码登录
[root@localhost ~]# mysql -uroot -p
修改root密码(必需是大写小写特殊符号数字才能修改成功)
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Lixin_.123';
mysql> flush privileges;
mysql> exit;
[root@localhost ~]# mysql -uroot -pLixin_.123
mysql> use mysql;
mysql> select user,host,plugin from user;
mysql> update user set Host='%' where User='root';
mysql> flush privileges;
如果需要降低密码强度(0或low代表最低要求):
mysql> install plugin validate_password soname 'validate_password.so';
mysql> select plugin_name, plugin_status from information_schema.plugins where plugin_name like 'validate%';
mysql> SHOW VARIABLES LIKE 'validate_password%';
要根据时面的字段名根据(字段名会变的)
+--------------------------------------+-------+
| validate_password.check_user_name | ON |
| validate_password.dictionary_file | |
| validate_password.length | 8 |
| validate_password.mixed_case_count | 1 |

mysql> set global validate_password_policy=LOW;
mysql> set global validate_password.length=6;
mysql> ALTER USER 'root'@'%' IDENTIFIED BY '123456';

安装 Docker Engine-Community
使用 Docker 仓库进行安装
在新主机上首次安装 Docker Engine-Community 之前,需要设置 Docker 仓库。之后,您可以从仓库安装和更新 Docker。
设置仓库安装所需的软件包。yum-utils 提供了 yum-config-manager ,并且 device mapper 存储驱动程序需要 device-mapper-persistent-data 和 lvm2。
[root@localhost redis-6.0.9]# yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
使用以下命令来设置稳定的仓库
[root@localhost redis-6.0.9]# yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安装 Docker Engine-Community
[root@localhost redis-6.0.9]# yum install -y docker-ce docker-ce-cli containerd.io
[root@centos ~]# systemctl start docker
Docker 安装完默认未启动。并且已经创建好 docker 用户组,但该用户组下没有用户。
