在/etc/my.cnf文件里边，把下边的内容写到[mysqld]下边：

character_set_server=utf8
init_connect='SET NAMES utf8'

/etc/my.cnf文件里边的整体内容如下：

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
character_set_server=utf8
init_connect='SET NAMES utf8'

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

systemctl start mariadb.service打开mariadb服务，systemctl status mariadb.service查看mariadb服务状态是active (running)，正常启动。

然后输出mysql这个命令按下回车键，之后在mysql提示符输入show variables like '%character_set%';按下回车键，之后就可以看到输出结果。quit可以退出mariadb命令行。

Nginx配置

我当前工作目录是/usr/local/openresty，若你现在不是的话，可以使用cd /usr/local/openresty切换工作目录。

把原有文件内容的两处修改了一下，首先有一处改成了如下所示：

location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

其次改成了listen 8084;，因为在天翼云上，80、8080、443端口都需要额外申请才能在安全组里边打开，所以我就把监听端口改成了8084，8084端口在安全组里边打开。

/usr/local/openresty/nginx/conf/nginx.conf里边的修改后整体内容如下：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
