CentOS7 服务器初始化-PySuper

一、配置静态IP

1、开启网络、更新

vi /etc/sysconfig/network-scripts/ifcfg-ens33

# 修改：

ONBOOT=on  ==> ONBOOT=yes

service network restart

yum update
yum install net-tools

2、网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static    # change
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=6efa4e7b-8bae-4998-a044-e7bc127bac2d
DEVICE=ens33
ONBOOT=yes

# 静态IP
IPADDR=111.111.111.151

# 默认网关 
GATEWAY=111.111.111.2

# 子网掩码
NETMASK=255.255.255.0

# DNS 配置
DNS1=111.111.111.2

# 谷歌地址
DNS2=8.8.8.8
NM_CONTROLLED=no

# vi /etc/resolv.conf
nameserver 111.111.111.2
nameserver 8.8.8.8

# vi /etc/sysconfig/network-scripts/route-ens33
192.168.247.0 via 192.168.247.2
0.0.0.0 via 192.168.247.2

# vi /etc/sysconfig/static-routes
any net 192.168.247.0 netmask 255.255.255.0 gw 192.168.247.2
any net 0.0.0.0 netmask 0.0.0.0 gw 192.168.247.2

3、配置防火墙

# 重启
service network restart

# 关闭
systemctl stop firewalld
systemctl disable firewalld

二、安装Python

1、安装依赖

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel
yum -y install db4-devel libpcap-devel xz-devel
yum install libffi-devel -y
yum install epel-release -y
yum install gcc -y
yum install wget -y

2、安装Python

wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
tar -xvJf Python-3.7.2.tar.xz
cd Python-3.7.2
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

3、安装pipenv

pip3 install pipenv

ln -s /usr/local/python3/bin/pipenv /usr/bin/pipenv
cd project_name
pipenv --python 3.7

4、配置cookiecutter

pip3 install cookiecutter

mkdir project
cd project
git clone https://github.com/pydanny/cookiecutter-django.git
/usr/local/python3/bin/cookiecutter cookiecutter-django

# 然后就是一系列的参数填写

三、配置数据库

MySQL

1、安装MySQL

rpm -qa | grep mariadb
rpm -e mariadb-libs-5.5.68-1.el7.x86_64 --nodeps
rpm -qa | grep mariadb

cd /usr/local/
mkdir mysql
cd mysql/
tar -xvf mysql-8.0.22-1.el7.x86_64.rpm-bundle.tar

rpm -ivh mysql-community-common-8.0.22-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-libs-8.0.22-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-client-8.0.22-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-server-8.0.22-1.el7.x86_64.rpm --nodeps --force
rpm -qa | grep mysql

2、配置MySQL

mysqld --initialize;
chown mysql:mysql /var/lib/mysql -R;
systemctl start mysqld.service;
systemctl enable mysqld;

cat /var/log/mysqld.log | grep pa   # 查看密码

mysql -uroot -p

进入数据库修改

-- 修改密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

-- 重登
create user 'root'@'%' identified with mysql_native_password by 'root';
grant all privileges on *.* to 'root'@'%' with grant option;
flush privileges;

-- 修改加密规则
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root' PASSWORD EXPIRE NEVER;
flush privileges;

3、配置防火墙

# 安装并配置 iptables 防火墙
yum -y install iptables-services
systemctl enable iptables;
systemctl start iptables;

# 命令编辑防火墙，添加端口
vim /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8090 -j ACCEPT

# 防火墙重启并自启
systemctl restart iptables.service
systemctl enable iptables.service

Redis

1、安装redis

yum install -y gcc 
wget http://download.redis.io/releases/redis-5.0.3.tar.gz
tar -zxvf redis-5.0.3.tar.gz
cd redis-5.0.3
make install PREFIX=/usr/local/redis

2、后台启动

cp /usr/local/redis-5.0.3/redis.conf /usr/local/redis/bin/

vi redis.conf
# 把 daemonize no 改为 daemonize yes
./redis-server redis.conf

4、开机启动

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

vi /etc/systemd/system/redis.service
# 复制粘贴上面的service配置(ExecStart配置成自己的路径)

# 设置开机启动
systemctl daemon-reload
systemctl start redis.service
systemctl enable redis.service

ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis
redis

4、服务操作命令

# 启动redis服务
systemctl start redis.service

# 停止redis服务
systemctl stop redis.service

# 重新启动服务
systemctl restart redis.service

# 查看服务当前状态
systemctl status redis.service

# 设置开机自启动
systemctl enable redis.service

# 停止开机自启动
systemctl disable redis.service
