Docker分离部署MySQL、Nginx+Tomcat复制共享

防伪码：失去只是一种姿势,得到并不等同于幸福

项目需求：

1、nginx容器作为整个架构中前端服务器监听80端口接收用户的jsp页面请求，并将用户的jsp请求分发给tomcat
web容器，tomcat容器需要连接mysql数据库容器。

2、nginx容器做为前端服务器可以直接响应用户的静态页面请求，jsp动态页面请求交给tomcat容器处理（静动分离）

3、通过session复制共享：session replication，实现tomcat服务器之间同步session，使session保持一致。

注：http://yw666.blog.51cto.com/11977292/1888747，session复制共享在前文详细讲解过，此处不再赘述。

如图所示：

制作nginx镜像

from docker.io/centos:centos6

add nginx-1.6.0 /nginx-1.6.0

run yum -y install gcc pcre pcre-devel zlib-devel make

run useradd nginx -s /sbin/nologin

run cd /nginx-1.6.0 && ./configure --prefix=/nginx --user=nginx --group=nginx && make &&
make install

run echo "daemon off;" >> /nginx/conf/nginx.conf

run echo ‘ip1=$(cat /etc/hosts | grep tomcat1 | awk ‘"‘{print "‘$1‘"}‘"‘)‘ >>
/7.sh

run echo ‘ip=$(cat /etc/hosts | grep tomcat2 | awk ‘"‘{print "‘$1‘"}‘"‘)‘ >>
/7.sh

run echo "sed -i -e ‘33 i"‘\u‘"pstream backend {‘ -e ‘33 i"‘\s‘"erver ""‘"‘$ip‘"‘"":8080
weight=1;‘ -e ‘33 i"‘\s‘"erver ""‘"‘$ip1‘"‘"":8080 weight=1;}‘ -e ‘46 i"‘\p‘"roxy_pass http://backend;‘ /nginx/conf/nginx.conf" >> /7.sh

run echo "/nginx/sbin/nginx" >> /7.sh

cmd source /7.sh

用docker build 生成nginx镜像

制作tomcat镜像

from docker.io/centos:centos6

add apache-tomcat-7.0.54 /apache-tomcat-7.0.54

add jdk1.7.0_65 /jdk1.7.0_65

add 123.sh /123.sh

add profile /profile

run mv /jdk1.7.0_65 /java

run mv /apache-tomcat-7.0.54 /tomcat7

add server.xml /tomcat7/conf/server.xml

add context.xml /tomcat7/conf/context.xml

run cp -rf /profile /etc/profile

run echo ‘ip1=$(ifconfig | grep Bcast | awk ‘"‘{print "‘$2‘"}‘"‘ | awk -F : ‘"‘{print
"‘$2‘"}‘)" >> /8.sh

run echo ‘ip2=$(cat /etc/hosts | grep mysql | awk ‘"‘{print "‘$1‘"}‘"‘)‘ >> /8.sh

run echo "sed -i ‘118 "‘i\a‘"ddress="‘"‘"‘"‘$ip1‘"‘"‘"‘"‘""
/tomcat7/conf/server.xml" >> /8.sh

run echo "sed -i ‘23 i"‘\u‘"rl="‘"‘jdbc:mysql://"‘"‘$ip2‘"‘":3306/javatest‘"‘"/>‘
/tomcat7/conf/context.xml" >> /8.sh

add mysql-connector-java-5.1.22-bin.jar /tomcat7/lib/mysql-connector-java-5.1.22-bin.jar

add 456.sh /456.sh

cmd source /456.sh

编写tomcat守护进程脚本

program="/tomcat7/bin/startup.sh"

progress="tomcat"

while true;

sleep 10

progremflag=`ps -ef |grep $progress|wc -l`

echo $progremflag

if [ $progremflag -le 10 ];then

$program >/dev/null 2>&1 &

done

编写cmd启动时要执行的脚本

用docker build 生成tomcat镜像

制作mysql镜像

from docker.io/centos:centos6

add cmake-2.8.12 /cmake-2.8.12

add mysql-5.5.38 /mysql-5.5.38

run yum -y install ncurses-devel gcc gcc-c++

run cd /cmake-2.8.12 && ./configure && gmake && gmake install

run cd /mysql-5.5.38 && cmake -DCMAKE_INSTALL_PREFIX=/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
-DWITH_EXTRA_CHARSETS=all -SYSCONFDIR=/etc && make && make install

run rm -rf /etc/my.cnf

run cp /mysql-5.5.38/support-files/my-medium.cnf /etc/my.cnf

run cp /mysql-5.5.38/support-files/mysql.server /mysqld

run chmod 777 /mysqld

run groupadd mysql

run useradd -M -s /sbin/nologin mysql -g mysql

run chown -R mysql:mysql /mysql

run /mysql/scripts/mysql_install_db --user=mysql --basedir=/mysql/ --datadir=/mysql/data/

run ./mysqld start && cd /mysql/bin && echo "grant all privileges on *.* to ‘root‘@‘%.%.%.%‘
identified by ‘123456‘;" | ./mysql -u root && echo "create database javatest;" | ./mysql -u root && echo "create table javatest.yw(id int);" | ./mysql -u root

cmd cd /mysql/bin && ./mysqld_safe
