4 安装环境

初始化系统
设置软件源
aliyun , remi, mysql

设置aliyun库$ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo# 设置 remi 库, 设置 mysql 库$ yum install http://rpms.famillecollet.com/enterprise/remi-release-7.rpm# 由于mysql 版权方面的限制, centos 7 没有内置mysql 服务器, 必须从mysql 官方进行安装$ yum install http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

设置 nginx 源

源地址: nginx: Linux packages创建 vi/etc/yum.repos.d/nginx.repo
, 并且填充以下内容来安装 yum repository 库
[nginx]name=nginx repobaseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/gpgcheck=0enabled=1

替换OS
为 “rhel” 或 “centos”替换OSRELEASE
为 5”, “6”, 或“7”
更新元数据

更新元数据$ yum makecache

安装软件
常用软件和nmp 软件

更新系统$ yum update# 安装常用软件$ yum install vim git supervisor redis# 安装 php 基于 remi , 所以需要安装 remi 源$ yum install --enablerepo=remi-php70 php php-pdo php-fpm php-mbstring php-mcrypt php-gd php-mysqli php-zip# 安装 nginx$ yum install nginx --enablerepo=nginx# 安装 mysql server$ yum install mysql-server

启动服务

启动服务$ systemctl start php-fpm mysqld nginx supervisord

开机自启动

开机启动$ systemctl enable php-fpm mysqld nginx supervisord

初始化数据库
启动mysql并且获取密码
$ systemctl start mysqld# mysql 5.7 在安装完成的时候会生成一个临时密码, 我们需要找到错误日志 /var/log/mysqld.log来获取这个临时密码# use below command to see the password:$ grep 'temporary password' /var/log/mysqld.log [Note] A temporary password is generated for root@localhost: _ab3BAKulW?r

**初始化 mysql **
$ mysql_secure_installationSecuring the MySQL server deployment.Enter password for user root: ******New password: ******Re-enter new password: ******The 'validate_password' plugin is installed on the server.The subsequent steps will run with the existing configurationof the plugin.Using existing password for root.Estimated strength of the password: 100 Change the password for root ? ((Press y|Y for Yes, any other key for No) : *Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : yBy default, a MySQL installation has an anonymous user,allowing anyone to log into MySQL without having to havea user account created for them. This is intended only fortesting, and to make the installation go a bit smoother.You should remove them before moving into a productionenvironment.Remove anonymous users? (Press y|Y for Yes, any other key for No) : YSuccess.Normally, root should only be allowed to connect from'localhost'. This ensures that someone cannot guess atthe root password from the network.Disallow root login remotely? (Press y|Y for Yes, any other key for No) : N... skipping.By default, MySQL comes with a database named 'test' thatanyone can access. This is also intended only for testing,and should be removed before moving into a productionenvironment.Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N ... skipping.Reloading the privilege tables will ensure that all changesmade so far will take effect immediately.Reload privilege tables now? (Press y|Y for Yes, any other key for No) : YSuccess.All done!

设置密码的方法
$ mysql -uroot -p******mysql> set password for 'root'@'localhost' = password('markzhao123456');mysql> exit
