linux 安装步骤

linux 安装步骤

1. 安装JDK

   1.1 查看云端目前支持安装的jdk版本

   [root@localhost ~]# yum search java|grep jdk

   1.2 选择版本后，安装（执行以下命令会自动安装jdk相关依赖

   [root@localhost ~]# yum install -y java-1.8.0-openjdk

   1.3 安装完成，验证是否安装成功

   [root@localhost ~]# java -version

2. 安装mysql

   1.1 获取mysql yum社区的下载文件

   关闭防火墙

   1.2 放到 root路径下

   1.3 将下载好的安装包挂载到本地

   yum localinstall mysql80-community-release-el8-1.noarch.rpm

   1.4 查看是否挂载成功

   yum repolist enabled | grep "mysql.-community."

   1.5 禁用centos8.0自带的mysql模块：yum module disable mysql

   1.6 安装mysql：yum install mysql-community-server

   1.7 启动mysql服务 service mysqld start 如果报错 执行systemctl restart mysqld.service

   1.8 查看mysql服务启动状态service mysqld status

   mysql服务相关命令

   启动服务：service mysqld start
   停止服务：service mysqld stop
   重启服务：service mysqld restart
   查看服务状态：service mysqld status
   ​
   设置mysql开机自启：
   systemctl enable mysqld
   systemctl daemon-reload

   1.9 查看mysql安装时生成的随机密码：grep 'temporary password' /var/log/mysqld.log

   2.0 登录mysql

   mysql -uroot -p'刚获取到的随机密码'
   ​

   2.1 安装mysql后第一次登录需要修改密码

   ALTER USER 'root' @'localhost' IDENTIFIED BY '你的密码';

   2.2 开放mysql远程访问

   创建权限记录：
   CREATE user 'root'@'%' IDENTIFIED BY 'root123';
   ​
   授权：
   GRANT ALL PRIVILEGES ON *.* TO 'root' @'%' WITH GRANT OPTION;
   ​
   修改密码过期策略：
   ALTER USER 'root' @'localhost' IDENTIFIED BY '你的密码' PASSWORD EXPIRE NEVER;
   ​
   重新修改密码：
   ALTER USER 'root' @'%' IDENTIFIED WITH mysql_native_password BY '你的密码';
   ​
   刷新权限：
   FLUSH PRIVILEGES;

3. 安装redis （都在根目录下）

   1.1 服务器设置相应的端口号

   1.2 安装redis数据库

   yum install redis

   1.3 下载fedora的epel仓库

   yum install epel-release

   1.4 启动redis服务

   systemctl start redis

   1.5 查看redis状态

   systemctl status redis

   systemctl stop redis 停止服务

   systemctl restart redis 重启服务

   6.设置开机自启动

   systemctl enable redis

   7.开放端口号

   firewall-cmd --zone=public --add-port=80/tcp --permanent

   firewall-cmd --zone=public --add-port=6379/tcp --permanent

   8.查看端口

   netstat -lnp|grep 6379

   9.设置redis 远程连接和密码

   输入命令vi /etc/redis.conf进入编辑模式

   注释 bind 127.0.01

   protected-mode no

   密码可设可不设

   10.重启redis

   systemctl restart redis

   11.进入redis

   命令redis-cli -h 127.0.0.1 -p 6379

   然后输入info,提示必须验证

4. 安装nginx

   1.1 执行如下 创建nginx yum配置文件

   [root@localhost ~] cd /etc/yum.repos.d/

   touch nginx.repo

   不要复制下面的

   [nginx-stable]
   name=nginx stable repo
   baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
   gpgcheck=1
   enabled=1
   gpgkey=https://nginx.org/keys/nginx_signing.key
   module_hotfixes=true

   chmod -R 755 nginx.repo

   1.2 执行如下命令进行yum安装nginx

   yum install nginx

1.3 查看nginx版本

# 查看nginx版本
nginx -v
​
# 查看编译参数
nginx -V

这里一定要看编译参数 放前端打包的地址 默认为 /usr/share/nginx

1.4 nginx.conf配置

vi /etc/nginx/nginx.conf

 

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    # access_log  /var/log/nginx/access.log  main;  #内存小的话 可以注释掉

   # sendfile        on;
   #tcp_nopush     on;
   # keepalive_timeout  65;
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
send_timeout 600s;

    #access_log  /var/log/nginx/access.log  main;
    client_max_body_size 1024M;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   300;
    types_hash_max_size 2048;

    #gzip  on;
    include /etc/nginx/conf.d/*.conf;
}

1.5 子配置 示例

vi /etc/nginx/conf.d/test.conf

server {
    listen 80;
    server_name  localhost;
    location / {  # 一定要有 “/”
      
 # add_header Cache-Control "no-cache, no-store";
 # add_header Access-Control-Allow-Origin *;
 # add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
        root /data/web;
        try_files $uri $uri/ /index.html;
    }
    
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
    location /api{
    #proxy_pass http://localhost:8888;
    }
}

这个是我的

server {
    listen	80;
    server_name  pay.aiqingyinghang.com;	
    #error_page   500 502 503 504  /50x.html;
   
     location / {
                    root   /usr/share/nginx/vue/dist;
                    try_files $uri $uri/ /index.html;
     }
    location /org {
                    alias  /usr/share/nginx/pay;
                    try_files $uri $uri/ /index.html;
     }
    location /50x.html {
                    root   html;
     }
 
	
}

1.6 测试nginx配置是否OK

执行 nginx -t

出现 success 即可

1.7 启动nginx

找到路径 cd /usr/sbin

./nginx

1.8 停止

nginx -s stop

1.9 重新启动nginx

nginx -s reload
