PHP酌摇、Mysql和Nginx的安裝請(qǐng)參照：
CentOS7快速搭建LNMP環(huán)境
安裝Composer
Laravel是使用composer來(lái)做包依賴(lài)管理的描焰，Laravel的安裝也同樣需要composer纸兔。所以我們搭建好了PHP、Mysql留攒、Nginx（Apache）之后跃脊，還需要安裝composer。
這里我只做composer的安裝介紹。
Composer網(wǎng)址
- composer下載
curl -sS https://getcomposer.org/installer | php
- composer移動(dòng)到系統(tǒng)$PATH可以搜索到的路徑下吹泡，這樣以后可以直接在命令行使用composer命令
mv composer.phar /usr/local/bin/composer
- 修改composer的執(zhí)行權(quán)限
chmod +x /usr/local/bin/composer
- 查看是否已經(jīng)安裝成功
composer -v
看到看到終端會(huì)輸出以下信息骤星，說(shuō)明已經(jīng)安裝成功了。
[root@lmc ~]# composer -v

安裝Laravel
composer安裝之后我們就可以安裝Laravel了
- 安裝Laravel
composer global require "laravel/installer"
[root@lmc ~]# composer global require "laravel/installer"
Changed current directory to /root/.config/composer
Using version ^1.3 for laravel/installer
./composer.json has been created

Writing lock file
Generating autoload files
[root@lmc ~]# laravel -v
-bash: laravel: command not found
安裝完成之后我們發(fā)現(xiàn)不能直接使用laravel命令
但是我們看到laravel其實(shí)已經(jīng)安裝完成了
[root@lmc ~]# ls .config/composer/vendor/bin/ -l
total 0
lrwxrwxrwx 1 root root 28 Jun 4 07:12 laravel -> ../laravel/installer/laravel
為了使用方便爆哑，我們將laravel命令放到系統(tǒng)的$PATH里面
vi ~/.bashrc
在最后加上laravel所在的路徑洞难，我的路徑是/root/.config/composer/vender/bin/
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export PATH=/root/.config/composer/vendor/bin/:$PATH
為了生效，執(zhí)行下面命令
source ~/.bashrc
現(xiàn)在我們直接使用命令
laravel -v
看到下面的信息說(shuō)明我們可以直接使用laravel命令了
