因为是测试环境，故
systemctl stop firewalld
yum remove firewalld
setenforce 0
首先是搭建tomcat
tomcat服务器运行时是需要JDK支持的，所以必须配置好相关的
依赖环境
我的yum源是阿里云的，所以JDK的包直接yum安装就可以了
yum –y install java-1.8.0-openjdk
yum -y install java-1.8.0-openjdk-headless
java -version 检查安装版本是否一致
依赖环境安装好之后就开始安装tomcat
因事先有准备好tar，所以直接解压即可
tar -xf apache-tomcat-8.0.30.tar.gz
mv移动解压出来的目录并改名到 /usr/local/tomcat
查改目录下子目录或文件齐全
ls /usr/local/tomcat
bin/ //主程序目录
lib/ //库文件目录
logs/ //日志目录
temp/ //临时目录
work/ //自动编译目录jsp代码转换servlet
conf/ //配置文件目录
webapps/ //页面目录
/usr/local/tomcat/bin/startup.sh 启动tomcat即可
因业务需要，需要添加多一个9090端口
vim /usr/local/tomcat/conf/server.xml
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="9090" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
接着就是./shutdown.sh
./startup.sh
netstat -anput | grep java
接下来是nginx
老规矩，安装依赖环境
yum -y install gcc pcre-devel openssl-devel zlib-devel
因为公司要求需要到ssl，所以还需要下载相对应的ssl的版本
wget ftp://ftp.openssl.org/source/old/1.0.1/openssl-1.0.1-beta2.tar.gz
接着就是解压，放到你想放到的目录上，本人是比较喜欢放到/usr/local，故：
tar zxvf openssl-1.0.1-beta2.tar.gz
mv openssl-1.0.1-beta2 /usr/local/openssl
然后给nginx创建一个不能登陆的用户
useradd -s /sbin/nologin nginx
解压nginx包
tar zxvf nginx-1.12.2.tar.gz
进入到生成的目录里
./configure --prefix=/usr/local/nginx1.10.3
--with-openssl=/usr/include/openssl
--with-openssl=/usr/local/openssl # 刚才已经是openssl放到了/usr/local/openssl了，这里指定一下
--with-http_ssl_module
--with-http_v2_module
--with-pcre
--with-http_stub_status_module
模块也可以按照自身需求进行更改，接下来是编译了
make&&make install
创建nginx的软连接
ln -s /usr/local/nginx/sbin/nginx /sbin/
如果想要nginx支持PHP文件，则需要修改配置nginx.conf让其支持PHP文件（两处地方）：
location / {
root html;
index index.php index.html index.htm;
}
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi.conf;
}
nginx 启动
netstat -anput | grep 80
接下来MySQL,同上，准备好了tar包

yum -y install perl-JSON 安装依赖环境
tar zxvf mysql-5.7.17.tar
rpm -Uvh mysql-community-*.rpm
ls /var/lib/mysql 查看数据库目录
systemctl start mysql
systemctl enable mysql
netstat -anput | grep 3306
ls /var/run/mysqld/mysqld.pid
ls /var/log/mysqld.log
ls /var/lib/mysql
与数据库服务相关的信息
主配置文件 日志文件 socket文件 PID文件 数据库目录的位置 进程所有 者和组 数据目录所有者和组
grep password /var/log/mysqld.log 查看数据库初始化密码
mysql -uroot -p'xxxxxxxxxx'
首次使用原密码登入需要修改密码后才能操作
mysql>alter user root@"localhost" identified by "qwer!@1234"; 重置新密码
额外：
show variables like "%password%";
set global validate_password_policy=0; //降低策略
set global validate_password_length=6; //修改密码长度
```
永久设置
```vim /etc/my.cnf
[mysqld]
validate_password_policy=0
validate_password_length=6
Systemctl restart mysqld
补充一个tomcat的配置文件server.xml多实例的

然后在修改好的路径上创建相对应的文件即可，然后把原本的webapps里面的所有目录文件cp到webapps1里面即可
