MySQL

1. 安装（略，或直接安装LNMP）

2. 配置外网访问

$ vim /etc/my.cnf
+ [mysqld]
+ port = 3306
+ bind-address = 0.0.0.0

$ cd /usr/local/rocketmq/bin/

$ vim runserver.sh
- JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
+ JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx128m -Xmn128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m"

$ vim runbroker.sh
- JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
+ JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx128m -Xmn128m"

Tomcat

1. 安装

$ wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.30/bin/apache-tomcat-9.0.30.tar.gz

# 修改端口
$ vim /etc/sysconfig/iptables
# 重启端口
$ service iptables restart
# 查看端口
$ iptables -L -n

Spring Security

Filter -> Interceptor -> Aspect -> Controller
OncePerRequestFilter 重复执行的filter只需要一次执行

1. AbstractUserDetailsAuthenticationProvider.java
     private class DefaultPostAuthenticationChecks implements UserDetailsChecker
         -> isAccountNonLocked() -> isEnabled() -> isAccountNonExpired()
2. DaoAuthenticationProvider.java
     protected void additionalAuthenticationChecks
         -> check username and password
3. AbstractUserDetailsAuthenticationProvider.java
     private class DefaultPreAuthenticationChecks implements UserDetailsChecker
         -> isCredentialsNonExpired()

USERNAME_NOT_FOUND(1004, "认证失败：用户名不存在"),
BAD_CREDENTIALS(1005, "认证失败：密码错误"),
ACCOUNT_DISABLED(1006, "认证失败：用户不可用"),
ACCOUNT_LOCKED(1007, "认证失败：用户锁定"),
ACCOUNT_EXPIRED(1008, "认证失败：用户过期"),
CREDENTIALS_EXPIRED(1009, "认证失败：证书过期"),
