篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了centos7安装jdk+tomcat+nginx+mysql相关的知识，希望对你有一定的参考价值。

公司新项目要在linux下部署，搭建一下java运行环境，记录一下。

1去官网下载mysql，下载后并解压，我把mysql安装在/usr/local/mysql路径下

tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local/mysql

2进入mysql目录，建立data文件夹

[root@localhost local]# cd /usr/local/mysql
[root@localhost mysql]# mkdir data

3新建不能登陆的mysql用户

useradd -r -M -s /sbin/nologin mysql

4修改mysql目录所有者为mysql用户和mysql组

chown -R mysql.mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql

5进入/usr/local/mysql目录，初始化mysql，后面那个是初始密码，要记住

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

6复制my.cnf文件，并修改/etc/my.cnf

cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character-set-server=utf8
collation-server=utf8_general_ci
default-storage-engine=INNODB
#server_id = .....
# socket = .....

7进行mysql.support-files目录，复制mysql.server到/etc/init.d/mysqld，加入开机运行

[root@localhost mysql]# cd support-files/
[root@localhost support-files]# cp mysql.server /etc/init.d/mysqld
[root@localhost support-files]# chmod +x /etc/init.d/mysqld
[root@localhost support-files]# chkconfig --add mysqld

查看是否成功

chkconfig --list mysqld

8mysql加入环境变量

vi /etc/profile #把mysql服务加入系统环境变量：在最后添加下面这一行
export PATH=$PATH:/usr/local/mysql/bin
:wq! #保存退出
source /etc/profile  #使配置立刻生效

9登录后修改密码

[root@localhost tmp]# service mysqld start
Starting MySQL. SUCCESS!
[root@localhost tmp]# mysql -uroot -p
Enter password:
mysql> SET PASSWORD = PASSWORD(\'123456\');
mysql> flush privileges;

二jdk安装

1下载jdk，解压并移动到安装路径

tar -zxvfjdk-8u73-linux-x64.tar.gz -C /usr/local/jdk8

2加入环境变量

vi /etc/profile
# 在export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL下添加
export JAVA_HOME=/usr/local/jdk8
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
#保存后，执行source /etc/profile使其生效

3验证是否成功java -vsersion

三安装tomcat

1解压并安装到指定路径

# 创建用户
groupadd tomcat
useradd -s /bin/bash -g tomcat tomcat
 
# 下载：
wget http://apache.opencas.org/tomcat/tomcat-7/v7.0.68/bin/apache-tomcat-7.0.68.tar.gz
# 解压：
tar -zxvf apache-tomcat-7.0.68.tar.gz
# 复制：
cp -R ./apache-tomcat-7.0.68 /usr/local
cd /usr/local/apache-tomcat-7.0.68
# 修改权限：
chown -R tomcat:tomcat apache-tomcat-7.0.68
# 启动：
sh ./bin/startup.sh

2将8080端口添加到防火墙例外并重启

1 2	`firewall-cmd --zone=public --add-port=8080/tcp` `--permanent` `firewall-cmd --reload`

3访问http://ip/8080

四安装nginx

安装nginx前，前提是安装了gcc-c++,还要安装一些依赖库

1安装perl

mkdir /usr/local/perl
cd perl5.22
./Configure -des -Dprefix=/usr/local/ perl -Dusethreads -Uversiononly
make
make test
make install

2安装pcre

mkdir /usr/local/pcre
tar zxvf pcre-8.35.tar.gz
cd pcre-8.35
./configure --prefix=/usr/local/pcre
make
make install

3安装openssl

mkdir /usr/local/openssl
tar zxvf openssl-1.0.1h.tar.gz
cd openssl-1.0.1h
./config --prefix=/usr/local/openssl
make
make install
vi /etc/profile
export PATH=$PATH:/usr/local/openssl/bin
:wq!
source /etc/profile

4安装zlib

mkdir /usr/local/zlib
tar zxvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure --prefix=/usr/local/lib/zlib
make
make install

5安装nginx

#添加用户和用户级
groupadd nginx
useradd -g nginx nginx -s /bin/false
mkdir /usr/local/nginx
tar zxvf nginx-1.6.0.tar.gz
cd nginx-1.6.0
./configure --prefix=/usr/local/nginx --without-http_memcached_module --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/root/tool/openssl-1.0.2g/ --with-zlib=/root/tool/zlib-1.2.8/ --with-pcre=/root/tool/pcre-8.37
#注意：--with-openssl=/usr/local/src/openssl-1.0.1h --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.35指向的是源码包解压的路径，而不是安装的路径，否则会报错
make
make install

#添加80端口到防火墙
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
#启动nginx
/usr/local/nginx/sbin/nginx

nginx -s reload ：修改配置后重新加载生效
nginx -s reopen ：重新打开日志文件
nginx -t -c /path/to/nginx.conf 测试nginx配置文件是否正确

关闭nginx：
nginx -s stop :快速停止nginx
quit ：完整有序的停止nginx

其他的停止nginx 方式：

ps -ef | grep nginx

kill -QUIT 主进程号：从容停止Nginx
kill -TERM 主进程号：快速停止Nginx
pkill -9 nginx ：强制停止Nginx

启动nginx:
nginx -c /path/to/nginx.conf

平滑重启nginx：
kill -HUP 主进程号

7设置nginx开机启动

vi /etc/init.d/nginxd  #编辑启动文件添加下面内容
!/bin/bash

chkconfig: - 85 15
description: Nginx is a World Wide Web server.
processname: nginx
nginx=/usr/local/nginx/sbin/nginx

conf=/usr/local/nginx/conf/nginx.conf
case $1 in

$nginx -c $conf

echo " done"

   ;;  

esac
:wq! #保存退出

注意(centos7没有killall命令，要先安装，yum install psmisc)

chmod +x /etc/init.d/nginxd #赋予文件执行权限

chkconfig --add nginxd#添加到服务

chkconfig nginxd on #设置开机启动

/etc/init.d/nginxd restart #重启

8nginx和tomcat整合，修改nginx配置文件

        {
                listen       80;
                server_name  localhost;
