1. 准备安装介质

安装介质下载:

mongodb的安装方式,我通常使用二进制包的方式,内网不能配置连接外网的yum源;

官方建议的mongodb下载地址为: Downloads.mongodb.org

但实际上,这个地址,很难找到下载表,正常下载,通常可以用下面的下载地址选择下载:

https://www.mongodb.org/dl/linux/x86_64

我这里下载的是: 3.2.5 版本对应的 mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz

如果将整个mongodb安装过程已经编写了脚本,可以获取安装脚本,用脚本执行安装;

如果手动安装,则可跳过此步;

手工安装mongodb的脚步的执行过程,一般如下:

mkdir -p /root/{software,scripts}
wget -q http://ptmaster.test.cn/files/init/mongodb_install.sh -O /root/scripts/mongodb_install.sh
cd /root/scripts
./mongodb_install.sh -p 27117

2. 添加mongodb用户和环境变量,修改系统设置

添加用户:

groupadd mongodb 
useradd -g mongodb mongodb

创建mongodb脚本目录

mkdir -p /home/mongodb/scripts/

修改目录权限:

chown -R mongodb:mongodb /home/mongodb/scripts/

在 /etc/profile 中添加 mongodb 用户的环境变量:

# MongoDB Environment Variables
export PATH=$PATH:$HOME/bin:/usr/local/mongodb/bin:/home/mongodb/scripts/

是上面的变量生效:

source /etc/profile

实际操作过程如下:

[root@yq-mapp-otadb248 etc]# id mongodb 
id: mongodb: No such user 
[root@yq-mapp-otadb248 etc]# 
[root@yq-mapp-otadb248 etc]# 
[root@yq-mapp-otadb248 etc]# groupadd mongodb 
useradd -g mongodb mongodb[root@yq-mapp-otadb248 etc]# useradd -g mongodb mongodb 
[root@yq-mapp-otadb248 etc]# 
[root@yq-mapp-otadb248 etc]# 
[root@yq-mapp-otadb248 etc]# id mongodb 
uid=801(mongodb) gid=801(mongodb) groups=801(mongodb) 
[root@yq-mapp-otadb248 etc]#

mongodb要求hugepage设置为禁用,soft limit设置足够大,可以在一开始修改,也可以到后面修改;

cat /etc/security/limits.d/90-nproc.conf

修改这个文件中下列的值

* soft nproc 2048

确保: soft nproc 的值至少是 soft nofile 值的一半;

修改后,退出当前用户,重新进入一下,设置就可以生效了;

禁用 hugepage 的值:

# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

备注:上面两个警告,现在不修改也不影响安装过程,后面会提示。

3. 安装mongodb软件

上传并解压软件:

cd /usr/local
rz mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz
tar -zxvf mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8.tgz
ln -sv mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8 /usr/local/mongodb

修改文件权限:

chown -R mongodb:mongodb mongodb-linux-x86_64-rhel62-3.2.5-20-g07e21d8
chown -R mongodb:mongodb /usr/local/mongodb

实际操作过程如下:

4. 创建mongodb实例所需的目录和配置文件

创建mongodb实例所需目录:

mkdir -p /data/mongo_27117/{db,log,tmp}

创建mongodb实例配置文件所需目录和文件:

mkdir -p /etc/mongodb
touch /etc/mongodb/mongo_27117.conf

根据需要配置mongodb的启动参数,我的启动参数配置内容如下:

vim /etc/mongodb/mongo_27117.conf

dbpath=/data/mongo_27117/db 
logpath=/data/mongo_27117/log/mongo_27117.log 
pidfilepath = /data/mongo_27117/tmp/mongo_27117.pid 
storageEngine = wiredTiger 
wiredTigerCacheSizeGB = 2 
syncdelay = 30 
wiredTigerCollectionBlockCompressor = zlib 
port=27117 
auth = true 
directoryperdb = true 
oplogSize=2048 
logappend=true 
fork=true 
#rest=true 
journal = true 
journalCommitInterval = 50 
slowms = 200

修改目录、文件的权限和属组:

chown -R mongodb:mongodb /data/mongo_27117/
chown -R mongodb:mongodb /etc/mongodb

确认目录和配置文件都已经准备完毕:

ls -l /data/mongo_27117/
ls -l /etc/mongodb
cat /etc/mongodb/mongo_27117.conf

该步骤实际操作过程如下:

[root@yq-mapp-otadb248 local]# 
[root@yq-mapp-otadb248 local]# mkdir -p /data/mongo_27117/{db,log,tmp} 
[root@yq-mapp-otadb248 local]# mkdir -p /etc/mongodb

5. 启动mongodb实例,修改管理员密码

使用下面的命令启动mongodb服务:

/usr/local/mongodb/bin/mongod --config /etc/mongodb/mongo_27117.conf

确认密码,mongodb的管理员密码,可以根据各自的规则设置:

echo $MONGODB_ROOT_PASS
mongodb_020248_Pass

修改管理员密码,注意 mongodb 3.2要对admin授予三个角色,这点与之前的版本不同:

/usr/local/mongodb/bin/mongo --port=27117
db.createUser({user:'useradmin',pwd:'mongodb_020248_Pass',roles:[ { "role" : "clusterAdmin", "db" : "admin" }, { "role" : "userAdminAnyDatabase", "db" : "admin" }, { "role" : "dbAdminAnyDatabase", "db" : "admin" } ] })
db.auth("useradmin","mongodb_020248_Pass")
db.system.users.find();

生成密码后,使用新用户和密码登陆mongo,确认状态:

/usr/local/mongodb/bin/mongo --port=27117 -u useradmin -p mongodb_020248_Pass --authenticationDatabase admin

该步骤操作过程如下;

[root@yq-mapp-otadb248 local]# 
[root@yq-mapp-otadb248 local]# ps -ef|grep mongo 
root 32295 30115 0 12:12 pts/0 00:00:00 grep mongo

6. 为应用创建业务账号

创建一个 admin / admin 用户,具有可以自行创建用户和数据库的权限,密码业务自己再修改:

db.createUser({user:'admin',pwd:'admin',roles:[{role:'userAdminAnyDatabase',db:'admin'},{role:'dbAdminAnyDatabase',db:'admin'}]})

验证业务账号登陆:

/usr/local/mongodb/bin/mongo --port=27117 -u admin -p admin --authenticationDatabase admin

该步骤,实际操作过程如下:

> 
> db.system.users.find().pretty() 
{ 
"_id" : "admin.useradmin", 
"user" : "useradmin", 
"db" : "admin", 
"credentials" : {

7. 实例启动时的报警处理

在mongodb启动过程中,有时会提示一些警告,其中常见的两类警告处理过程如下:

警告1:

提示:

2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 2048 processes, 8192 files. Number of processes should be at least 4096 : 0.5 times number of files.

处理方式,根据提示,将 processes 值,由现在的 2048,修改为4096,甚至更高的值。

ps -ef|grep mongod
cat /proc/32321/limits
cat /etc/security/limits.d/90-nproc.conf 
vim /etc/security/limits.d/90-nproc.conf

2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] 
2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.
2016-10-19T12:12:59.097+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'

确认:

cat /sys/kernel/mm/transparent_hugepage/enabled
cat /sys/kernel/mm/transparent_hugepage/defrag

处理:

echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

该步骤,实际操作过程如下:

[root@yq-mapp-otadb248 limits.d]# cat /sys/kernel/mm/transparent_hugepage/enabled 
[always] madvise never 
[root@yq-mapp-otadb248 limits.d]# cat /sys/kernel/mm/transparent_hugepage/defrag 
[always] madvise never 
[root@yq-mapp-otadb248 limits.d]# 
[root@yq-mapp-otadb248 limits.d]# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled 
[root@yq-mapp-otadb248 limits.d]# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag 
[root@yq-mapp-otadb248 limits.d]# 
[root@yq-mapp-otadb248 limits.d]# cat /sys/kernel/mm/transparent_hugepage/enabled 
always madvise [never] 
[root@yq-mapp-otadb248 limits.d]# cat /sys/kernel/mm/transparent_hugepage/defrag 
always madvise [never] 
[root@yq-mapp-otadb248 limits.d]# 
[root@yq-mapp-otadb248 limits.d]#

8. 创建mongodb实例服务管理脚本

为了方便对mongodb实例的启动和停止,可以先创建mongodb的启动脚本,停止脚本,然后在 /etc/init.d/ 目录下创建一个服务脚本,这样就可以用 service 进行实例管理了。

脚本1:启动脚本:

vim /home/mongodb/scripts/mongodb_start.sh

#!/bin/sh 
# the scripts is used to start mongodb instance with port 27117. 
# created by zhaofx on 20161019. 
echo -n "Starting MongoDB port 27117 ... " 
/usr/local/mongodb/bin/mongod --config /etc/mongodb/mongo_27117.conf &

脚本二:停止脚本:

vim /home/mongodb/scripts/mongodb_stop.sh

#!/bin/bash 
# the scripts is used to stop mongodb instance with port 27117. 
# created by zhaofx on 20161019. 
echo -n "Stopping MongoDB port 27117" 
pid=`ps -o pid,command ax | grep mongod | awk '!/awk/ && !/grep/ {print $1}'`; 
if [ "${pid}" != "" ]; then 
kill -2 ${pid}; 
fi

脚本三:服务脚本:

vim /etc/init.d/mongodb

vim /etc/init.d/mongodb 
#! /bin/sh 
# the scripts is used to mange mongodb service with linux service type. 
# created by zhaofx on 20161019. 
PATH=/usr/local/mongodb/bin:/sbin:/bin:/usr/sbin:/usr/bin 
NAME=mongodb 
start(){ 
/home/mongodb/scripts/mongodb_start.sh 
} 
stop(){ 
/home/mongodb/scripts/mongodb_stop.sh 
} 
test -x $DAEMON || exit 0 
set -e 
case "$1" in 
start) 
start 
;; 
stop) 
stop 
;; 
*) 
N=/etc/init.d/$NAME 
echo "Usage: $N {start|stop}" >&2 
exit 1 
;; 
esac 
exit 0

修改脚本的属组,添加执行权限:

chown -R mongodb:mongodb /home/mongodb/scripts/ 
chown mongodb:mongodb /etc/init.d/mongodb 
chmod +x /home/mongodb/scripts/mongodb_start.sh 
chmod +x /home/mongodb/scripts/mongodb_stop.sh 
chmod +x /etc/init.d/mongodb

最后服务启动和停止mongodb实例的过程为:

[root@yq-mapp-otadb248 ~]# 
[root@yq-mapp-otadb248 ~]# service mongodb stop 
Stopping MongoDB port 27117 
[root@yq-mapp-otadb248 ~]# 
[root@yq-mapp-otadb248 ~]# 
[root@yq-mapp-otadb248 ~]# 
[root@yq-mapp-otadb248 ~]# service mongodb start 
Starting MongoDB port 27117 ... [root@yq-mapp-otadb248 ~] 
about to fork child process, waiting until server is ready for connections. 
forked process: 36088 
child process started successfully, parent exiting 
[root@yq-mapp-otadb248 ~]#

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
