centos7.7安裝php7.3的lnmp環境和composer詳細步驟


1.更新源
  yum update
2.安裝nginx
  yum install nginx
3.啟動nginx
  service nginx start
4.訪問http://你的ip

  如果想配置域名,見最下面。

5.安裝mysql:

安裝mysql源 yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
安裝: yum install mysql mysql-server
啟動: /etc/init.d/mysqld start 或者 service mysqld restart

重置密碼:mysql -u root -p
幾率報錯 Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
原因:權限問題
解決: sudo chown -R root:root /var/lib/mysql (兩個root都可以改為擁有者,但是需要保持一致)
重啟服務
service mysqld restart

登陸mysql
mysql -u root -p //按回車直接可以登陸,剛安裝完mysql是沒有密碼的
修改mysql密碼

  use mysql;
  低版本修改:update user set password=password('你的密碼') where user='root';

  高版本修改:update user set authentication_string = password('你的密碼'), password_expired = 'N', password_last_changed = now() where user = 'root';
        alter user 'root'@'localhost' identified by '你的密碼';
  如果說密碼強度不夠,可以查看密碼級別:SHOW VARIABLES LIKE "%password%";
  然后設置為低級別:SET GLOBAL validate_password_policy=0;
  最后退出;
  exit;
  重啟 service mysqld restart
  允許遠程訪問
  1.必要時加入以下命令行,為root添加遠程連接的能力。鏈接密碼為'你的密碼'
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你的密碼' WITH GRANT OPTION;
    FLUSH PRIVILEGES;

  2.打開my.cnf文件
    添加一行 bind-address=0.0.0.0
  3.重啟mysql

6.安裝php
  yum install php php-devel //php5.6版本
  如果想安裝7.3
  首先安裝 EPEL 源
  1.yum install epel-release //安裝 EPEL 源
  2.yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm //安裝 REMI 源
  3.yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xml

  4.PHP的安裝目錄/etc/opt/remi/php73/ php.ini也在里面
    找到php.ini 里面fix_pathinfo 修改成0 但是不能看phpinfo();

    操作
    systemctl restart php73-php-fpm #重啟
    systemctl start php73-php-fpm #啟動
    systemctl stop php73-php-fpm #關閉
    systemctl status php73-php-fpm #檢查狀態

7.最后在yum update 更新php資源 方便以后更新擴展用

8.安裝composer
  curl -sS https://getcomposer.org/installer | php73
  mv composer.phar /usr/local/bin/composer
  這樣輸入composer會報錯 :/usr/bin/env: php: No such file or directory
  解決方法
  cd usr/bin
  cp php73 php
  在輸入composer就好了

  更改鏡像為阿里雲:composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

9.安裝git
  yum -y install git

10.下載laravel框架
  composer create-project --prefer-dist laravel/laravel 項目名稱 "6.*"

  composer create-project --prefer-dist laravel/laravel laravelxs "6.*"

  修改composer文件。
  cd /root/.config/composer/
  vi auth.json

  {
    "bitbucket-oauth": {},
    "github-oauth": {},
    "gitlab-oauth": {},
    "gitlab-token": {
      "github.com": "在git上生成的token"
    },
    "http-basic": {},
    "bearer": {}
  }
  添加
  "github.com": "在git上生成的token"

 11.nginx域名的配置

  創建文件:域名.conf 

  里面的內容:

server{
  listen 80;
  server_name 你的域名;
  access_log /var/log/nginx/access.log;
  error_log /var/log/nginx/error.log;
  index index.html index.htm index.php;
  root  你的項目目錄;

  location / {
    try_files $uri $uri/ /index.php$is_args$args;
  }

  location ~ .*\.(php|php5)?$
  {
    #fastcgi_pass unix:/dev/shm/php-cgi.sock;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_connect_timeout 180;
    fastcgi_read_timeout 600;
    fastcgi_send_timeout 600;
    fastcgi_index index.php;
    fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
    include fastcgi_params;

  }

  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
  {
    expires 30d;
  }

  location ~ .*\.(html|htm|js|css)?$
  {
    expires 8h;
  }
}
