==============安装centos 7.0=======================
选择最小安装，将相关的"调试工具"、“兼容性程序库”、“开发工具”选中。
此操作是为了减少后期安装或编译相关服务时出现依赖、或环境的问题。
硬盘分区，可根据个人的习惯而定，不清楚的可以直接选择系统自动分区，
由于个人的习惯，本人的分区如下，仅供参考：
/boot 500M 用于启动Linux的核心文件
swap 5120M(5G) Linux下的交换分区，又称为虚拟内存，一般是物理内存的2倍，但不建议超过8G
/ 51200M(50G) 所有系统的文件等，都在该分区下
/home 剩下的空间 用户主目录，新建的用户的目录将会出现在这里
================关闭不需要的安全设置，使用其他的安全管理================
vi /etc/selinux/config //关闭Selinux
SELINUX=disabled //原为enforcing改为disabled
------------------------或使用以下命令关闭SELINUX---------------------------------------
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
setenforce 0
systemctl stop firewalld //停止系统默认的防火墙
systemctl mask firewalld //屏蔽服务(让它不能启动)
reboot //重启让selinux配置生效
=================管理工具安装======================
安装ifconfig、ntsysv、updatedb、lrzsz(上传下载)、wget(远程http下载)功能
yum install -y chkconfig net-tools telnet ntsysv mlocate lrzsz wget lsof setuptool system-config-securitylevel-tui system-config-network-gui system-config-network-tui system-config-date tcpdump
yum install -y vim nano //安装编辑器
==============更新Centos 7.0 repo源=====================
yum install -y epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum clean all
yum makecache
yum install -y python-pip
pip install --upgrade pip
pip install requests
=====安装nginx yum安装的第三方repo源文件(使用编译安装则不需要)=======
mkdir /root/software
cd /root/software
wget https://mirrors.ustc.edu.cn/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
rpm -ivh epel-release-7-11.noarch.rpm
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
=====安装mysql yum安装的第三方repo源文件(使用编译安装则不需要)=======
cd /root/software //进入源文件集中文件夹
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm //下载
yum localinstall -y mysql57-community-release-el7-8.noarch.rpm //通过rpm安装得到repo源
yum repolist enabled | grep "mysql.-community." //检查mysql源是否安装成功
=================各种环境的预装======================
yum install -y make cmake gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers gd gd-devel perl expat expat-devel nss_ldap unixODBC-devel libxslt-devel libevent-devel libtool-ltdl bison libtool zip unzip gmp-devel //安装各种环境所需要的插件
yum install -y pcre pcre-devel //安装PCRE(可与预装环境同步进行)
yum update -y //升级补丁
=======================安装mysql及初始设置mysql=======================
yum install -y bison-devel libaio-devel //预装mysql环境
yum install -y perl-Data-Dumper //预装mysql所需环境
yum install -y mysql-server //安装mysqld
service mysqld start //启动mysql
systemctl enable mysqld.service //开机自启动
grep 'temporary password' /var/log/mysqld.log //mysql5.7版本后，初始密码不再为空，默认随机生成，可通过该命令查询
mysql -u root -p //进入mysql
alter user root@localhost identified by '三种或以上的八位字符'; 默认需要先修改密码，才能其他操作
exit; //退出mysql管理
----------------------------设置mysql 不分大小写----------------------
vi /etc/my.cnf
[mysqld]

service mysqld restart //重启mysql
=================MySQL运维小知识======================
MySQL高占用CPU、内存，有可能是由于进程未能及时释放，可以通过简单的设置，可以有效的解决这个问题。
mysql -uroot -p
mysql> show global variables like '%timeout';
mysql> set global interactive_timeout=100;
-----------------上述的，在重启mysqld.service后失效-----------------------------------
vi /etc/my.cnf
[mysqld]
interactive_timeout=20
wait_timeout=20
------------------------------上述，任何时候都生效-------------------------
-----------------------------mysql创建远程用户并授权---------------------------
mysql -uroot -p
mysql> create user root identified by '123456';
mysql> grant all privileges on . to 'root'@'%'identified by '123456' with grant option;
mysql> flush privileges;
-----------------------------mysql创建数据库-----------------------------
mysql> CREATE DATABASE lottery DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
----------------------------mysql修改指定用户的密码-------------------------------
update mysql.user set password=password('新密码') where User="test" and Host="localhost";
---------------------------mysql删除指定用户-------------------------------------

====================tomcat日志分割定期删除catalina.out=============
每天晚上11点50切割日志文件，同时删除超过30天的日志
log_path=/opt/tomcat/logs
d=date +%Y-%m-%d
d90=date -d'30 day ago' +%Y-%m-%d
cd ${log_path} && cp catalina.out $log_path/cron/catalina.out.$d.log
echo > catalina.out
rm -rf $log_path/cron/catalina.out.${d90}.log
添加权限
chmod 777 /shell/log.sh
编辑crontab
crontab -e
50 23 * sh /shell/log.sh
----------------------另一种方法---------------------------
crontab -e
- 5 find /usr/logs/ -name ".20" -ctime +7 -exec rm -rf {} \;
systemctl start tomcat7.service
===============配置访问同一个项目下不同的文件夹===========
先将原本的<host>配置注释掉，然后新增如下内容：
<Host name="hhcp.itrxm.com" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="/data/tomcat/tomcat/webapps/ROOT" debug="0" reloadable="true" />
</Host>
<Host name="hhcphb.itrxm.com" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="/data/tomcat/tomcat/webapps/HBH5" debug="0" reloadable="true" />
</Host>
================SSL环境搭建==================================
在nginx的conf中，进行做对应的修改
server {
listen 80;
server_name 域名地址;
rewrite ^(.*)$ https://$host$1 permanent;
}
server {
listen 443;
server_name x;
ssl on;
ssl_certificate /etc/nginx/vhost/ssl/certificate.crt;
ssl_certificate_key /etc/nginx/vhost/ssl/private.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location / {
client_max_body_size 16m;
client_body_buffer_size 128k;
proxy_pass http://IP地址:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_next_upstream off;
proxy_connect_timeout 30;
proxy_read_timeout 300;
proxy_send_timeout 300;
}
}在tomcat 中的server.xml中修改：
<!--
<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />
-->
修改为：
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150"
SSLEnabled="true"
scheme="https"
secure="true"
keystoreFile="/opt/tomcat/tomcat/conf/cert/201802031124.pfx" //绝对路径，否则容易出错
keystoreType="PKCS12"
keystorePass="201802031124"
clientAuth="false"
SSLProtocol="TLSv1+TLSv1.1+TLSv1.2"
ciphers="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA256"/>
并新加节点：
<Valve className="org.apache.catalina.valves.RemoteIpValve"
remoteIpHeader="x-forwarded-for"
remoteIpProxiesHeader="x-forwarded-by"
protocolHeader="x-forwarded-proto"/>
重启tomcat服务
systemctl restart tomcat.service
注：没有若只有key及crt文件的证书，可以进入
https://www.myssl.cn/tools/merge-pfx-cert.html
中进行生成一个pfx文件的证书，并设置一个密码。
=================通过VisualVM对Tomcat性能监控==================
JMX下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/extras/catalina-jmx-remote.jar
catalina-jmx-remote.jar包下载完成后放到Tomcat的lib目录下
vim catalina.sh
----------------------------------在注释下面添加如下内容------------------------------------
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=7090
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=被监控的服务器IP地址
-Dcom.sun.management.jmxremote.authenticate=true
-Dcom.sun.management.jmxremote.password.file=/var/tomcat/tomcat/conf/jmxremote.password
-Dcom.sun.management.jmxremote.access.file=/var/tomcat/tomcat/conf/jmxremote.access"
cd /var/tomcat/tomcat/conf
vim jmxremote.access
monitorRole readonly
controlRole readwrite
vim jmxremote.password //要与运行tomcat的权限一致
monitorRole 25DWdl2&D^W
controlRole 25DWdl2&D^W
chmod 0400 jmxremote.password //密码文件应该是只读的，只能由Tomcat运行用户
systemctl restart tomcat.service
至此，整套环境及系统搭建部署完毕。
