搭建版本

安装NGINX

wget http://nginx.org/download/nginx-1.8.1.tar.gz
yum install pcre pcre-devel openssl openssl-devel -y        #安装依赖；
yum install zlib zlib-devel gcc gcc-c++ autoconf automake
useradd -s /sbin/nologin nginx -M
tar -zxvf nginx-1.8.1.tar.gz 
cd nginx-1.8.1
./configure --prefix=/opt/nginx181/            #指定安装目录；
make && make install
ln -s /opt/nginx181/sbin/nginx /usr/local/bin/nginx        #做软连接，可直接通过命令启动；
nginx         #启动
nginx -t         #检查配置
ngins -s reload  #重新加载
netstat -ntlup|grep nginx
ps -aux |grep nginx

验证：

安装mysql：

yum -y install https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
yum -y install yum-utils
yum-config-manager --disable mysql57-community
yum-config-manager --enable mysql55-community
yum repolist enabled | grep mysql
yum -y install mysql-community-client

rpm -e MariaDB-common-10.1.41-1.el7.centos.x86_64 --nodeps    #移除mariadb，没有报错则跳过此步骤；
yum install -y mysql-community-server

systemctl start mysqld.service

#修改初始密码
#方法1：
mysqladmin -uroot password '123.com'

#方法2：
update user set password=password('456.com') where user='root' and host='localhost';
flush privileges;

#方法3：
set password=password('123.com');
flush privileges;

#优化数据库
mysql -uroot -p
drop database test;
select user,host from mysql.user;
drop user ''@'localhost';
drop user 'root'@'::1';
#注意：grant新建的用户drop删除不了，需要用delete删除。
grant all on *.* to root@'a' identified by '123.com';
delete from mysql.user where user='root' and host='a';
