ubuntu下apache2+php+mysql环境配置

安装apache2

# 安装
sudo apt-get install apache2

# 执行文件地址
/etc/init.d/apache2

# 配置文件目录
/etc/apache2

# 启动apache2
sudo apache2ctl -k start

# 停止apache2
sudo apache2ctl -k stop

# 重新启动apache2
sudo apache2ctl -k restart

# 如果重启遇到一下问题
# AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
#需要在apache2.conf 文件中加上 ServerName 127.0.0.1
