PHP gd库增加jpeg支持

wget http://www.ijg.org/files/jpegsrc.v9b.tar.gz
tar zxvf jpegsrc.v9b.tar.gz
cd jpeg-9b
./configure –prefix=/usr/local/jpeg –enable-shared –enable-static
make && make install

cd /alidata/server/temp/php-5.6.30/ext/gd
make clean
/alidata/server/php56/bin/phpize
./configure –with-php-config=/alidata/server/php56/bin/php-config –with-png-dir –with-freetype-dir=/usr/local/freetype.2.1.10 –with-jpeg-dir=/usr/local/jpeg –with-zlib-dir –with-gd
make && make install
/etc/init.d/php56-fpm restart

如果仍然不行,重新编译PHP。

如果重新编译仍然不行,那么就先不加gd选项编译PHP,然后再加上gd选项编译一次。

CentOS6.5 下Nginx 的安装与配置

原文链接:https://www.cnblogs.com/DanBrown/p/8005184.html

1.安装必须环境

nginx的编译需要c++,同时prce(重定向支持)和openssl(https支持)也需要安装。

请顺序安装依赖

1  yum install gcc-c++  
2  yum -y install pcre*  
3  yum -y install openssl*

2.,下载nginx-1.9.9.tar.gz,可放在 /usr/local/ 目录下   ps:我这里使用的老本你可以尝试新版

1  [root@admin ~]# cd /usr/local/  
2  [root@admin local]# wget http://nginx.org/download/nginx-1.9.9.tar.gz

3.解压及编译

1 [root@admin local]# tar -zxvf nginx-1.9.9.tar.gz

4.进入nginx目录

1 [root@admin local]# cd nginx-1.9.9

5.设置安装目录为 /usr/local/nginx

1 [root@admin nginx-1.9.9]# ./configure --prefix=/usr/local/nginx

开始编译安装

1  [root@admin nginx-1.9.9]# make  
2  [root@admin nginx-1.9.9]# make install

我这里是阿里服务器在(控制台)实例中配置一下端口,,本机中再开放一下80端口(不知道请查我的博客中有讲过如何开放指定端口);

 

 

 

启动nginx服务

进入安装目录 /usr/local/nginx

1 [root@admin ~]# cd /usr/local/nginx  
2 [root@admin sbin]# ./nginx

查看进程,可以看到nginx的master和worker进程

1     [root@admin sbin]# ps -ef | grep nginx  
2     root     32150     1  0 13:28 ?        00:00:00 nginx: master process ./nginx  
3     nobody   32151 32150  0 13:28 ?        00:00:00 nginx: worker process  
4     root     32154 28494  0 13:28 pts/1    00:00:00 grep nginx

可以通过访问ip:80测试,看到页面这样的提示就说明安装成功

重启的命令:

1 [root@admin sbin]# ./nginx -s reload

最后可以配置一下命令 添加nginx为系统服务(service nginx start/stop/restart)

1、在/etc/init.d/目录下编写脚本,新建名为nginx的文件然后把脚本代码粘贴进去 注意:配置 文件位置我的在usr/local/下若果不是这个路径你需要修改)

脚本代码

然后执行

2 [root@example ~]# chmod 755 /etc/init.d/nginx
3 [root@example ~]# chkconfig --add nginx

nginx启动、停止、无间断服务重启

1 [root@example ~]# service nginx start
2 
3 [root@example ~]# service nginx stop
4 
5 [root@example ~]# service nginx reload

好了蕾丝(@.@)

注补充:

  停止服务  查进程号之后 kill -9 进程号 即可.

CentOS6.5安装Zookeeper

原文地址:https://www.cnblogs.com/duenboa/articles/6665169.html

1. 下载安装文件zookeeper-3.4.6.tar.gz
2. 还是copy到虚拟机的centos系统桌面
3. 新建/usr/loca/zookeeper文件夹
[root@localhost ~]# mkdir -pv /usr/local/zookeeper
4.拷贝文件到指定文件夹
[root@localhost ~]# cd /root/Desktop/
[root@localhost ~]# cp ./zookeeper-3.4.6.tar.gz /usr/local/zookeeper
5. 解压
[root@localhost ~]# tar -zxvf jdk-8u121-linux-x64.tar.gz
6. 配置环境变量
[root@localhost ~]#cd /etc/
[root@localhost ~]#cp ./profile ./profile.bak — 把文件备份一下
[root@localhost ~]#vi /etc/profile — 编辑此配置文件
在文件末尾添加此段内容: — 开始和–中间的一段.(注意,尽量保持环境变量名全大写,下划线隔开. 保持规范)
— 开始
export ZOOKEEPER_INSTALL=/usr/local/zookeeper/zookeeper-3.4.6/
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
— 结束
7. 配置文件修改
[root@localhost zookeeper-3.4.6]# cd /usr/local/zookeeper/zookeeper-3.4.6/conf/ — 进入文件所在路径
[root@localhost conf]# cp zoo_sample.cfg zoo.cfg — 将zoo.sample.cfg拷贝出一份zoo.cfg出来. 文件名强制
8. 文件内容如下:
[root@localhost conf]# vi zoo.cfg — 按i进入编辑模式. 修改完成之后, esc退出编辑模式, 大写字母Z双击即可保存.
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper — 这里要设置一下文件路径 路径必须存在,不存在的话就新建一个呗
dataLogDir=/tmp/zookeeper/log — 日志路径 路径必须存在,不存在的话就新建一个呗
# the port at which the clients will connect
clientPort=2181 — 如果是多机器的话,在clientPort处添加服务器的ip
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to “0” to disable auto purge feature
#autopurge.purgeInterval=1
修改完之后 通过 > # cat zoo.cfg 查看.
9. 开启服务,关闭服务, 查看
[root@localhost bin]# cd /usr/local/zookeeper/zookeeper.3.4.6/bin/
[root@localhost bin]# ./zkServer.sh stop — 停止服务
JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED
[root@localhost bin]# ./zkServer.sh start — 开启服务
JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper … STARTED
[root@localhost bin]# ./zkServer.sh status — 查看状态
JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: standalone
[root@localhost bin]#
[root@localhost bin]# ./zkCli.sh — 客户端启动, 可以查看启动状态和日志

云通讯访问报错:172001网络错误

172001,错误信息=网络错误
172001是无法连接我们的服务器,请求不到或者发不出请求,sdk本地打印的故障报错。需要按如下顺序排查:
a.先打印请求url确认serverIP是否传错; 
b.Linux系统试用:curl -l  https://app.cloopen.com:8883 测试下,看是否是通的,windows系统,在浏览器输入 https://app.cloopen.com:8883看是否正常; 
c.如果是在Linux下 centos版本大于6.0并且使用java开发,用java -version确认下jdk版本(在此环境下需要使用sunjdk,openjdk不行);
d. 在 /etc/hosts 文件里添加" 42.121.254.126  app.cloopen.com",重启服务器。

Linux免密码登录设置

原文地址:https://blog.csdn.net/furzoom/article/details/79139570

假设要登录的机器为192.168.1.100,当前登录的机器为192.168.1.101。

首先在101的机器上生成密钥(如果已经生成可以跳过):

$ ssh-keygen -t rsa

一路回车即可。

然后在将生成的公钥复制到机器100上的~/.ssh/authorized_keys中,使用如下命令:

$ ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.1.100

root为需要登录到机器100上的身份,需要替换成需要的用户名。

最后,测试免密码登录:

$ ssh root@192.168.1.100
