Ubuntu下使用apt方式安装Mysql8.0版本 以及 使用ppa搭建nginx+PHP+redis+mysql环境记录_ubuntu apt mysql8

一、Ubuntu下使用apt方式安装Mysql8.0版本

    在Ubuntu上使用apt-get install mysql会自动安装5.7版本(repositories上MySQL的版本是5.7，)。可以试试# apt search mysql8发现找不到任何内容，而搜索# apt search mysql能看到有5.7版本。因此我们不通过直接执行apt-get install mysql-server命令来安装我们要安装的MySQL8版本。mysql8.0版本的下载地址：MySQL :: Download MySQL Community Server

    安装方式可以自己手动下载一个一个包，然后按照一定顺序逐个安装，但那样真的很麻烦，要下载的包很多，而且顺序还不能错，直接安装mysql-community-server-core-dbgsym还会报错。比如下面：

#下载MYSQL 服务包
root@test:~# wget https://cdn.mysql.com//Downloads/MySQL-8.0/libmysqlclient21-dbgsym_8.0.25-1ubuntu18.04_amd64.deb
root@test:~# wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-community-server-core-dbgsym_8.0.25-1ubuntu18.04_amd64.deb
root@test:~# wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-community-client-dbgsym_8.0.25-1ubuntu18.04_amd64.deb
root@test:~# wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-community-client-core-dbgsym_8.0.25-1ubuntu18.04_amd64.deb
......
#直接安装mysql-community-server-core-dbgsym报错如下：
# dpkg -i mysql-community-server-core-dbgsym_8.0.25-1ubuntu18.04_amd64.deb 
mysql-community-server-core-dbgsym depends on mysql-community-server-core (= 8.0.25-1ubuntu18.04); however:
Package mysql-community-server-core is not installed.
dpkg: error processing package mysql-community-server-core-dbgsym (--install):

  所以建议的安装方式是通过下载apt来安装： MySQL :: Download MySQL APT Repository

# apt-get update
# wget https://repo.mysql.com//mysql-apt-config_0.8.17-1_all.deb
# dpkg -i mysql-apt-config_0.8.17-1_all.deb
# apt-get update
# apt-get install mysql-server
Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
# apt --fix-broken install
Processing triggers for libc-bin (2.27-3ubuntu1.3) ...
Processing triggers for man-db (2.8.3-2ubuntu0.1) ...
# apt-get install mysql-server
success 

    在执行dpkg -i mysql-apt-config_0.8.17-1_all.deb的时候会提示你选择MYSQL版本。执行apt-get install mysql-server会提示输入初始化root密码。安装前apt-get update不要有问题，我在dpkg安装时一直不能成功，因为apt-get update报错。有个package不能验证通过。

# apt-get update
Reading package lists... Done 
W: GPG error: http://repo.y.. main/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C8F1E19FE0C56BD4  
E：The repository 'http://repo.y.." main/ Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

    可以通过编辑/etc/apt/sources.list 去掉有问题的包后再尝试apt-get update，也可以试试网上提供的通用方法。我这里使用这个通用方法并没有成功，不过列在这里当个记录。
#网上提示可用的方法
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys　425956BB3E31DF51

二、Ubuntu下使用ppa搭建nginx+PHP+redis+mysql环境记录

ubuntu下使用ppa搭建nginx+PHP+redis+mysql环境的执行记录，以待后续留用。

    安装mysql的时候会要求输入2次root密码完成mysql初始密码设定，ppa安装的php默认是使用sock文件通信,一般会改成tcp使用默认的9000端口。可以使用以下两种启动命令，
systemctl restart/start/stop/status php7.1-fpm
service php7.1-fpm restart/start/stop/status
service nginx restart等

    另外在ubuntu上使用ondrej/php这个PPA安装php时，如果出现类似下面的报错：UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 92: ordinal not in range(128) 原因是当前系统不是UTF-8的locales，可以通过LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php命令解决。LC_ALL=C 是为了去除所有本地化的设置，让命令能正确执行。
