WordPress 安装和配置
环境
- 腾讯云
- CentOS 7.4
- 1C + 1G（最低配置）
- IP：193.112.211.201
- 推荐按此文章进行安装的时候可以把该 IP 替换成你的，方便直接复制
更新系统可更新软件
yum clean all
yum -y update
安装 Apache
yum install -y httpd
systemctl start httpd.service
systemctl enable httpd.service
安装 MySQL
先检查是否已经安装了 Mariadb
- 检查：
rpm -qa | grep mariadb
- 卸载：
rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
MySQL 5.5 安装和配置（内存 1G 推荐）
MySQL 5.6 安装和配置（如果内存没有大于 2G，请不要使用）
MySQL 5.7（推荐）
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum localinstall -y mysql57-community-release-el7-8.noarch.rpm
yum install mysql-community-server
systemctl enable mysqld.service
systemctl restart mysqld.service
MySQL 5.7 配置
- 默认 MySQL 5.7 安装完有一个随机密码生成，位置在：
/var/log/mysqld.log，里面有这样一句话：A temporary password is generated for root@localhost: 随机密码
- 如果初次要连上去需要填写该密码
- 我们也可以选择重置密码：
systemctl stop mysqld.service/usr/sbin/mysqld --skip-grant-tables --user=mysql
- 在启动一个终端：
mysql -u root mysql
UPDATE user SET authentication_string=PASSWORD('新密码') where USER='root';FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '上一步的新密码' WITH GRANT OPTION;systemctl restart mysqld.service
- 试一下：
mysql -h localhost -u root -p 然后输入密码，在 MySQL 终端输入：select 1;
- 如果报：
You must reset your password using ALTER USER statement before executing this statement，解决办法：
set global validate_password_policy=0; #密码强度设为最低等级
set global validate_password_length=6; #密码允许最小长度为6
set password = password('新密码');
FLUSH PRIVILEGES;
- YUM 安装的 MySQL 默认配置文件在：
vim /etc/my.cnf，默认有如下信息，会自己配置的可以改下。
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
