centos yum 安装php mysql

1 安装php7

查看 centos 版本

# cat /etc/centos-release

删除之前的 php 版本

# yum remove php* php-common

rpm 安装 Php7 相应的 yum源

CentOS/RHEL 7.x:

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

CentOS/RHEL 6.x:
# rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
 
yum安装php7

# yum install php70w php70w-opcache

2 安装mysql

一、检查系统是否安装其他版本的MYSQL数据
#yum list installed | grep mysql
#yum -y remove mysql-libs.x86_64
二、安装及配置
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
# rpm -ivh mysql-community-release-el6-5.noarch.rpm
# yum repolist all | grep mysql
安装MYSQL数据库
# yum install mysql-community-server -y
设置为开机启动(2、3、4都是on代表开机自动启动)
# chkconfig --list | grep mysqld
# chkconfig mysqld on
三、设置远程root启动mysql
# service mysqld start
设置root密码
# mysql_secure_installation
登陆root账号
# mysql -uroot -p 
建立远程root用户
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION;
mysql> flush privileges;
四、设置utf-8编码

查看mysql原本编码：
mysql> show variables like 'character%';
设置编码
# vi /etc/my.cnf
如下(少补)：utf8
centos yum 安装php mysql
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
sql_mode='NO_ENGINE_SUBSTITUTION'
[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8

[mysqld_safe]
default-character-set = utf8

[client]
default-character-set = utf8
centos yum 安装php mysql

utf8bm4

[client]
default-character-set=utf8mb4  

[mysqld]
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
skip-character-set-client-handshake = true  

[mysql]
default-character-set = utf8mb4

重启mysql

# service mysqld restart

再次查看编码：

centos yum 安装php mysql
     # mysql -uroot -p
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
