下面由composer教程栏目给大家介绍centos7.7安装php7.3的lnmp环境和composer详细步骤，希望对需要的朋友有所帮助！
1.更新源
yum update
2.安装nginx
yum install nginx
3.启动nginx
service nginx start
4.访问http://你的ip
如果想配置域名，见最下面。
5.安装mysql:
安装mysql源 yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
安装： yum install mysql mysql-server
启动： /etc/init.d/mysqld start 或者 service mysqld restart
重置密码：mysql -u root -p
几率报错 Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
原因：权限问题
解决： sudo chown -R root:root /var/lib/mysql (两个root都可以改为拥有者，但是需要保持一致)
重启服务
service mysqld restart
登陆mysql
mysql -u root -p //按回车直接可以登陆，刚安装完mysql是没有密码的
修改mysql密码
use mysql;
低版本修改：update user set password=password('你的密码') where user='root';
高版本修改：update user set authentication_string = password('你的密码'), password_expired = 'N', password_last_changed = now() where user = 'root';
alter user 'root'@'localhost' identified by '你的密码';
如果说密码强度不够，可以查看密码级别：SHOW VARIABLES LIKE "%password%";
然后设置为低级别：SET GLOBAL validate_password_policy=0;
最后退出；
exit;
重启 service mysqld restart
允许远程访问
1.必要时加入以下命令行，为root添加远程连接的能力。链接密码为'你的密码'
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你的密码' WITH GRANT OPTION;
FLUSH PRIVILEGES;
2.打开my.cnf文件
添加一行 bind-address=0.0.0.0
3.重启mysql
6.安装php
yum install php php-devel //php5.6版本
如果想安装7.3
首先安装 EPEL 源
1.yum install epel-release //安装 EPEL 源 2.yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm //安装 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的安装目录/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 #重启 systemctl start php73-php-fpm #启动 systemctl stop php73-php-fpm #关闭 systemctl status php73-php-fpm #检查状态
7.最后在yum update 更新php资源 方便以后更新扩展用
8.安装composer
curl -sS https://getcomposer.org/installer | php73<br/> mv composer.phar /usr/local/bin/composer
这样输入composer会报错 ：/usr/bin/env: php: No such file or directory
解决方法
cd usr/bin<br/> cp php73 php
在输入composer就好了
更改镜像为阿里云：composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
9.安装git
yum -y install git
10.下载laravel框架
composer create-project --prefer-dist laravel/laravel 项目名称 "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
创建文件：域名.conf
里面的内容：
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 你的项目目录;
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;
}
