下面由composer教程欄目給大家介紹centos7.7安裝php7.3的lnmp環境和composer詳細步驟，希望對需要的朋友有所幫助！
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
? ? 更改鏡像為阿里云：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; } }
