Swift Perfect 服务器配置（Ubuntu16.0.4 主机、虚拟机）

Mac 开发环境

brew install mysql@5.7 && brew link mysql@5.7 --force
mysql.server start
mysql_secure_installation mysql -uroot -p (默认密码为空，直接回车)
alter user 'root'@'localhost' identified by '新密码'；(MySQL 5.7. and later)

Ubuntu 16.0.4 Swift环境配置 (下载对应环境 https://swift.org/download/ Toolchain)

#.bashrc

export SWIFT_HOME=/opt/swift
export PATH=$SWIFT_HOME/usr/bin:$PATH

# source .bashrc

sudo apt-get install mysql-server mysql-client libmysqlclient-dev clang libcurl3 openssl libssl-dev uuid-dev libpython2.7-dev supervisor pkg-config libcurl4-openssl-dev

Ubuntu 16.0.4 MySQL数据库配置

基础命令：service mysql restart | service mysql start | service mysql stop

sudo mysql_secure_installation

配置项较多，如下所示：

#
VALIDATE PASSWORD PLUGIN can be used to test passwords...
Press y|Y for Yes, any other key for No: N (我的选项)

#
Please set the password for root here...
New password: (输入密码)
Re-enter new password: (重复输入)

#
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them...
Remove anonymous users? (Press y|Y for Yes, any other key for No) : N (我的选项)

#
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network...
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y (我的选项)

#
By default, MySQL comes with a database named 'test' that
anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (我的选项)

#
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y (我的选项) 

检查mysql服务状态：

systemctl status mysql.service

显示如下结果说明mysql服务是正常的：

● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: en
   Active: active (running) since Tue -- :: CST; 13min ago
 Main PID:  (mysqld)
    Tasks:  (limit: )
   CGroup: /system.slice/mysql.service
           └─ /usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pi

May  :: fileplay-ecs- systemd[]: Starting MySQL Community Server...
May  :: fileplay-ecs- systemd[]: Started MySQL Community Server.

在Ubuntu下MySQL缺省是只允许本地访问的，使用workbench连接工具是连不上的； 
如果你要其他机器也能够访问的话，那么需要改变/etc/mysql/my.cnf配置文件；

首先用根用户进入：直接回车

sudo mysql -uroot -p

mysql> use mysql;
mysql> flush privileges;

以root进入mysql后也可用命令给root设置密码：

GRANT ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY "";

新建数据库和用户 
用root用户新建数据和用作远程访问的用户

## 创建数据库weixx
CREATE DATABASE weixx;
## 创建用户wxx(密码654321) 并赋予其weixx数据库的所有权限
GRANT ALL PRIVILEGES ON weixx.* TO wxx@localhost IDENTIFIED BY ""; 

进行远程访问或控制配置

## 允许wxx用户可以从任意机器上登入mysql
GRANT ALL PRIVILEGES ON weixx.* TO wxx@"%" IDENTIFIED BY ""; 

$sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

这里我们注释掉这一行 #bind-address = 127.0.0.1

重启mysql
service mysql restart

mysql增大超时时间（24小时，需重启）

interactive_timeout=
wait_timeout=

mysql插入数据支持中文

#
[client]
default-character-set=utf8

[mysql]
no-auto-rehash
default-character-set=utf8

[mysqld]
character-set-server=utf8
init_connect='SET NAMES utf8'

Mysql频繁出现 Mysql mysql lost connection to server during query（同时解决设置utf8后，异端无法用utf8查看数据库【中文乱码】）

[mysqld]
skip-name-resolve

Supervisor让服务器项目后台运行

apt-get install supervisor

#没有/etc/supervisor/supervisord.conf文件，可按此方法生成

echo_supervisord_conf > /etc/supervisor/supervisord.conf 
#修改supervisor配置文件 /etc/supervisor/supervisord.conf #移至文件内容结尾 去掉 [include] 前面;
files = /etc/supervisor/conf.d/*.conf

 # script.sh 执行脚本,进入代码路径，执行命令

 cd /root/Code/PerfectTemplate
 .build/debug/PerfectTemplate 

# cd /etc/supervisor/conf.d, 创建并编辑 vim swiftServer.conf, swiftServer是我的文件名和program名
# ; 一定一定不能少

[program:swiftServer] ; //  program name
file=/tmp/supervisor.sock ;
command=sh script.sh ; // script name
process_name=%(program_name)s ;
directory=/opt ; // script path
autorestart=unexpected ; //当进程意外被kill或出现异常时，Supervisor会自动重启该进程。
user=root ; // user name 
[supervisord]
[supervisorctl]

输入supervisord -c /etc/supervisord.conf让你刚刚的配置生效.

输入supervisorctl start swiftServer启动并后台运行

输入supervisorctl status查询状态

supervisor 自启动

创建/usr/lib/systemd/system/supervisord.service文件；
写入：

# dservice for systemd (CentOS 7.0+)
# by ET-CS (https://github.com/ET-CS)
[Unit]
Description=Supervisor daemon

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl shutdown
ExecReload=/usr/bin/supervisorctl reload
KillMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

systemctl enable supervisord

验证一下是否为开机启动：systemctl is-enabled supervisord

supervisor 定期启动应用
