[root@nginx-200 ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

二、部署Tomcat服务器并Tomcat集群
## 解压jdk ：
[root@tomcat-202 /usr/local]# tar xf jdk-8u201-linux-x64.tar.gz
[root@tomcat-202 /usr/local]# ls
## 创建 jdk 软连接
[root@tomcat-202 /usr/local]# ln -s /usr/local/jdk1.8.0_201 /usr/local/jdk
## 解压 Tomcat
[root@tomcat-202 /usr/local]# tar xf apache-tomcat-8.5.60.tar.gz
## 创建tomcat软连接
[root@tomcat-202 /usr/local]# ln -s /usr/local/apache-tomcat-8.5.60 /usr/local/tomcat
[root@tomcat-202 /usr/local]# ls
########### 修改环境变量配置文件
[root@tomcat-202 ~]# vim /etc/profile
按G跳转至最后一行
按o 新起一行进入模式
粘贴以下内容
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib:/test
export PATH=$JAVA_HOME/bin:$PATH
export TOMCAT_HOME=/usr/local/tomcat
#按ESC退出插入模式，输入 :wq 退出
## 当前shell进程重新读取 /etc/profile 配置文件
[root@tomcat-202 ~]# source /etc/profile
[root@tomcat-202 /]# java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Tomcat started.
root@tomcat-202 /]# netstat -ntl
Active Internet connections (only servers)

upstream tomcat-apps {

}
server {

access_log /usr/local/nginx/logs/class1.com.access.log main;
location / {

}
}
server {
listen 80;
server_name www.class2.com;
access_log /usr/local/nginx/logs/class2.com.access.log main;
location / {
root /data/web-data/class2.com;
index index.html;
}
}
}
## 保存退出，重载nginx 服务器
[root@nginx-200 /usr/local/nginx]# /usr/local/nginx/sbin/nginx -s reload
三、admin跳板机：配置Ansible自动化运维
[root@admin-199 ~]# ssh-keygen -t rsa
[root@admin-199 ~]# ssh-copy-id 192.168.10.200
[root@admin-199 ~]# ssh-copy-id 192.168.10.202
[root@admin-199 ~]# ssh-copy-id 192.168.10.203
[root@admin-199 ~]# ssh-copy-id 192.168.10.204
[root@admin-199 ~]# ssh 192.168.10.200 hostname
nginx-200
[root@admin-199 ~]# ssh 192.168.10.202 hostname
tomcat-202
[root@admin-199 ~]# ssh 192.168.10.203 hostname
tomcat-203
[root@admin-199 ~]# ssh 192.168.10.204 hostname
tomcat-204
[root@admin-199 ~]# yum install ansible -y
[root@admin-199 ~]# ansible --version
ansible 2.9.27
## 创建主机清单
[root@admin-199 ~]# vim /etc/ansible/hosts
[nginx]
192.168.10.200
[tomcat]
192.168.10.202
192.168.10.203
192.168.10.204
[root@admin-199 ~]# ansible tomcat -m command -a "hostname"

四、安装部署mysql数据库服务器
## 安装 mariadb工具包，和服务器包
[root@mysql-225 ~]# yum install mariadb mariadb-server
.... .... ...
作为依赖被升级:
mariadb-libs.x86_64 1:5.5.68-1.el7
完毕！
####### 初始化数据库
[root@mysql-225 ~]# cd /var/lib/mysql/
[root@mysql-225 /var/lib/mysql]# mysql_install_db --datadir=/var/lib/mysql --user=mysql
[root@mysql-225 /var/lib/mysql]# ls
aria_log.00000001 aria_log_control mysql performance_schema test
### 启动mysql服务，监听3306 端口
[root@mysql-225 /var/lib/mysql]# systemctl start mariadb
[root@mysql-225 ~]# netstat -lntat
Active Internet connections (servers and established)

tcp6 0 0 :::22 :::* LISTEN
五、部署主从数据库
#主数据库：
[root@mysql-225 ~]# vim /etc/my.cnf
log_bin = mysql-bin
binlog_ignore_db = mysql
server_id = 225
MariaDB [(none)]> grant all privileges on *.* to root@'%' identified by "000000";
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant replication slave on *.* to 'user'@'192.168.10.226' identified by '000000';
Query OK, 0 rows affected (0.00 sec)
#从数据库
[root@mysql-226 ~]# vim /etc/my.cnf
log_bin = mysql-bin
binlog_ignore_db = mysql
server_id = 226
MariaDB [(none)]> change master to master_host='mysql-225',master_user='user',master_password='000000';
MariaDB [(none)]> start slave;
MariaDB [(none)]> show slave status\G;
